DESCRIPTION OF BUSINESS	'
	DESCRIPTION OF BUSINESS
	Rand Logistics, Inc. (the “Company”) is a shipping company that, through its operating subsidiaries, is engaged in the operation of bulk carriers on the Great Lakes. Rand Acquisition Corporation was incorporated in Delaware on June 2, 2004 as a blank check company whose objective was to acquire an operating business. On March 3, 2006, the Company, through its wholly-owned subsidiary, LL Acquisition Corp., acquired all of the outstanding shares of capital stock of Lower Lakes Towing Ltd. (“Lower Lakes Towing”) from the shareholders of Lower Lakes Towing, in accordance with the terms of the Stock Purchase Agreement, dated September 2, 2005, by and among the Company, LL Acquisition Corp. and the stockholders of Lower Lakes Towing, as amended. Immediately following completion of the acquisition, and in conjunction therewith, LL Acquisition Corp. and Lower Lakes Towing were amalgamated under Canadian law and the shares of capital stock of Grand River Navigation Company, Inc. (“Grand River”) and Lower Lakes Transportation Company (“Lower Lakes Transportation”) owned by Lower Lakes Towing at the time of the amalgamation were transferred to the Company's wholly-owned subsidiary, Rand LL Holdings Corp. (“Rand LL Holdings”). Upon completion of such transfer, the outstanding shares of Grand River not owned by Rand LL Holdings were redeemed in accordance with the terms of the Redemption Agreement, dated September 2, 2005, between Grand River and GR Holdings, Inc. Following completion of the foregoing transactions, as of March 3, 2006, each of Lower Lakes Towing, Grand River and Lower Lakes Transportation became indirect, wholly-owned subsidiaries of the Company. In conjunction with the foregoing transactions, as of March 3, 2006, the Company, formerly known as Rand Acquisition Corporation, changed its name to Rand Logistics, Inc.
	On February 4, 2011, Black Creek Shipping Company, Inc. (“Black Creek”), an indirect wholly-owned subsidiary of the Company, and Black Creek Shipping Holding Company, Inc. (“Black Creek Holdings”), a wholly-owned subsidiary of the Company and the parent corporation of Black Creek, were incorporated to acquire certain assets discussed in Note 11.
	On December 27, 2012, Lower Lakes Ship Repair Company Ltd. ("Lower Lakes Ship Repair"), a wholly-owned subsidiary of Lower Lakes Towing was incorporated under the laws of Canada. This subsidiary provides ship repair services exclusively for the Company.
	On March 11, 2014, Lower Lakes Towing (17) Ltd. ("Lower Lakes (17)"), a wholly-owned subsidiary of Lower Lakes Towing, was incorporated under the laws of Canada.

Accounting Policies [Abstract]	'
SIGNIFICANT ACCOUNTING POLICIES	'
	SIGNIFICANT ACCOUNTING POLICIES
	Basis of presentation and consolidation
	The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America and include the accounts of Rand Finance Corp. (“Rand Finance”), Rand LL Holdings and Black Creek Holdings, wholly-owned subsidiaries of the Company, the accounts of Lower Lakes Towing, Lower Lakes Transportation and Grand River, each of which is a wholly-owned subsidiary of Rand LL Holdings, Black Creek, which is a wholly owned subsidiary of Black Creek Holdings, Lower Lakes Ship Repair and Lower Lakes (17), each of which is a wholly-owned subsidiary of Lower Lakes Towing.
	The consolidated financial statements include the accounts of the Company and all of its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated.
	Cash and cash equivalents
	The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents.
	2	SIGNIFICANT ACCOUNTING POLICIES (continued)
	Accounts receivable and concentration of credit risk
	The majority of the Company’s accounts receivable are amounts due from customers and other accounts receivable, including insurance and Harmonized Sales Tax refunds.  The majority of accounts receivable are due within 30 to 60 days and are stated at amounts due from customers net of an allowance for doubtful accounts. The Company extends credit to its customers based upon its assessment of their creditworthiness and past payment history. Accounts outstanding longer than the contractual payment terms are considered past due. The Company has historically had no significant bad debts. Interest is not accrued on outstanding receivables.
	Revenue and operating expenses recognition
	The Company generates revenues from freight billings under contracts of affreightment (voyage charters) generally on a rate per ton basis based on origin-destination and cargo carried. Voyage revenue is recognized ratably over the duration of a voyage based on the relative transit time in each reporting period when the following conditions are met: the Company has a signed contract of affreightment, the contract price is fixed or determinable and collection is reasonably assured.  Included in freight billings are other fees such as fuel surcharges and other freight surcharges, which represent pass-through charges to customers for toll fees, lockage fees and ice breaking fees paid to other parties.  Fuel surcharges are recognized ratably over the duration of the voyage, while freight surcharges are recognized when the associated costs are incurred. Freight surcharges are less than 5% of total revenue.
	Marine operating expenses such as crewing costs, fuel, tugs and insurance are recognized as incurred or consumed and thereby are recognized ratably in each reporting period. Repairs and maintenance and certain other insignificant costs are recognized as incurred.
	The Company subcontracts excess customer demand to other freight providers.  Service to customers under such arrangements is transparent to the customer and no additional services are provided to customers.  Consequently, revenues recognized for customers serviced by freight subcontractors are recognized on the same basis as described above.  Costs for subcontracted freight providers, presented as “outside voyage charter fees” in the consolidated statements of operations, are recognized as incurred and therefore are recognized ratably over the voyage.
	The Company accounts for sales taxes imposed on its services on a net basis in the consolidated statements of operations.
	In addition, all revenues are presented on a gross basis.
	Vessel acquisitions
	Vessels are stated at cost, which consists of the purchase price and any material expenses incurred upon acquisition, such as initial repairs, improvements, delivery expenses and other expenditures to prepare the vessel for its initial voyage. Subsequent expenditures for conversions and major improvements are also capitalized when they appreciably extend the life, increase the earnings capacity or improve the efficiency or safety of the vessels. Significant financing costs incurred during the construction period of the vessels are also capitalized and included in the vessels' cost.
	Fuel and lubricant inventories
	Raw materials, fuel and certain operating supplies are accounted for on a first-in, first-out cost method (based on monthly averages). Raw materials and fuel are stated at the lower of actual cost (first-in, first-out method) or market. Operating supplies are stated at actual cost or average cost.
	2	SIGNIFICANT ACCOUNTING POLICIES (continued)
	Intangible assets and goodwill
	Intangible assets consist primarily of goodwill, deferred financing costs, trademarks, trade names and customer relationships and contracts. Intangible assets are amortized as follows:
	Trademarks and trade names	10 years straight-line
	Customer relationships and contracts	15 years straight-line
	Deferred financing costs are amortized on a straight-line basis over the term of the related debt, which approximates the effective interest method.
	Property and equipment
	Property and equipment are recorded at cost.  Depreciation methods for property and equipment are as follows:
	Vessels	5 - 25 years straight-line
	Leasehold improvements	7 - 11 years straight-line
	Vehicles	20% declining-balance
	Furniture and equipment	20% declining-balance
	Computer equipment	45% declining-balance
	Communication equipment	20% declining-balance
	Impairment of fixed assets
	Fixed assets (e.g. property and equipment) and finite-lived intangible assets (e.g. customer lists) are tested for impairment upon the occurrence of a triggering event that indicates the carrying value of such an asset or asset group (e.g. tugs and barges), might be no longer recoverable. Examples of such triggering events include a significant disposal of a portion of such assets, an adverse change in the market involving the business employing the related asset(s), a significant decrease in the benefits realized from an acquired business, difficulties or delays in integrating the business, and a significant change in the operations of an acquired business.
	Once a triggering event has occurred, the recoverability test employed is based on whether the intent is to hold the asset(s) for continued use or to hold the asset(s) for sale. If the intent is to hold the asset(s) for continued use, the recoverability test involves a comparison of undiscounted cash flows excluding interest expense, against the carrying value of the asset(s) as an initial test. If the carrying value of such asset(s) exceeds the undiscounted cash flow, the asset(s) would be deemed to be impaired. Impairment would then be measured as the difference between the fair value of the fixed or amortizing intangible asset and the carrying value of such asset(s). The Company generally determines fair value by using the discounted cash flow method. If the intent is to hold the asset(s) for sale and certain other criteria are met (i.e. the asset(s) can be disposed of currently, appropriate levels of authority have approved the sale and there is an actively pursuing buyer), the impairment test is a comparison of the asset’s carrying value to its fair value less costs to sell. To the extent that the carrying value is greater than the asset’s fair value less costs to sell, an impairment loss is recognized for the difference. The Company has determined that there were no adverse changes in our markets or other triggering events that could affect the valuation of our assets during the twelve month period ended March 31, 2014.
	2	SIGNIFICANT ACCOUNTING POLICIES (continued)
	Impairment of goodwill
	The Company annually reviews the carrying value of goodwill to determine whether impairment may exist. Accounting Standards Codification (“ASC”) 350 “Intangibles-Goodwill and Other” and Accounting Standards Update (“ASU”) 2011-08 Intangibles—Goodwill and Other (Topic 350) - Testing Goodwill for Impairment requires that goodwill and certain intangible assets be assessed annually for impairment using fair value measurement techniques. Specifically, goodwill impairment is determined using a three-step process. The first step of the goodwill impairment test is to perform a qualitative assessment before calculating the fair value of the reporting unit when testing goodwill for impairment. If the fair value of the reporting unit is determined, based on qualitative factors, to be more likely than not less than the carrying amount of the reporting unit, then entities are required to perform the two-step goodwill impairment test. The second step of the goodwill impairment test is used to identify potential impairment by comparing the fair value of a reporting unit with its carrying amount, including goodwill. The estimates of fair value of the Company’s two reporting units, which are the Company’s Canadian and US operations (excluding the parent), are determined using various valuation techniques with the primary techniques being a discounted cash flow analysis and peer analysis. A discounted cash flow analysis requires various judgmental assumptions, including assumptions about future cash flows, growth rates, and discount rates. The assumptions about future cash flows and growth rates are based on the Company’s forecast and long-term estimates. Discount rate assumptions are based on an assessment of the risk inherent in the respective reporting units. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired and the second step of the impairment test is unnecessary. If the carrying amount of a reporting unit exceeds its fair value, the second step of the goodwill impairment test is performed to measure the amount of impairment loss, if any. The third step of the goodwill impairment test compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. If the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination. That is, the fair value of the reporting unit is allocated to all of the assets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination and the fair value of the reporting unit was the purchase price paid to acquire the reporting unit.  As of March 31, 2014, the Company conducted the qualitative assessment and determined that the fair value of its two reporting units exceeded their carrying amounts and the remaining two-step impairment testing was therefore not necessary.  The Company has determined that there were no adverse changes in our markets or other triggering events that indicated that it is more likely than not that the fair value of our reporting units was less than the carrying value of our reporting units during the twelve month period ended March 31, 2014.
	Drydock costs
	Drydock costs incurred during statutory Canadian and United States certification processes are capitalized and amortized on a straight-line basis over the benefit period, which is generally 60 months. Drydock costs include costs of work performed by third party shipyards and subcontractors and other direct expenses to complete the mandatory certification process.
	Repairs and maintenance
	The Company’s vessels require repairs and maintenance each year to ensure the fleet is operating efficiently during the shipping season.  The majority of repairs and maintenance are completed in January, February, and March of each year when the vessels are inactive.  The Company expenses such routine repairs and maintenance costs.  Significant repairs to the Company’s vessels (whether owned or available to the Company under a time charter), such as major engine overhauls and major hull steel repairs, are capitalized and amortized over the remaining useful life of the upgrade or asset repaired, or the remaining lease term.
	2	SIGNIFICANT ACCOUNTING POLICIES (continued)
	Income taxes
	The Company accounts for income taxes in accordance with ASC 740 “Income Taxes”, which requires the determination of deferred tax assets and liabilities based on the differences between the financial statement and income tax bases of tax assets and liabilities, using enacted tax rates in effect for the year in which the differences are expected to reverse.  A valuation allowance is recognized, if necessary, to measure tax benefits to the extent that, based on available evidence, it is more likely than not that they will be realized.
	The Company classifies interest expense related to income tax liabilities, when applicable, as part of the interest expense in its consolidated statements of operations rather than income tax expense.  To date, the Company has not incurred material interest expenses or penalties relating to assessed taxation amounts.
	There is a current examination taking place by the U.S. taxing authorities for the financial year 2012 with no adjustments proposed as of the date of this Annual Report on Form 10-K. Lower Lakes was examined by the Canadian taxing authority for the tax years 2009 and 2010 and such examination is now complete.  This audit did not result in any material adjustments for such periods. The Company's primary U.S. state income tax jurisdictions are Illinois, Indiana, Michigan, Minnesota, Pennsylvania, Wisconsin and New York and its only international jurisdictions are Canada and its province of Ontario. The following table summarizes the open fiscal tax years for each major jurisdiction:
	Jurisdiction	Open Tax Years
	Federal (USA)	2010 – 2013
	Various states	2010 – 2013
	Federal (Canada)	2009 – 2013
	Ontario	2009 – 2013
	Foreign currency translation
	The Company uses the U.S. Dollar as its reporting currency.  The functional currency of the Company's Canadian subsidiaries is the Canadian Dollar.  The functional currency of the Company’s U.S. subsidiaries is the U.S. Dollar. Assets and liabilities denominated in foreign currencies are translated into U.S. Dollars at the rate of exchange at the balance sheet date, while revenue and expenses are translated at the average exchange rates prevailing during the respective month.  Components of stockholders’ equity are translated at historical exchange rates.  Exchange gains and losses resulting from translation are reflected in accumulated other comprehensive income or loss.
	Advertising costs
	The Company expenses all advertising costs as incurred. These costs are included in general and administrative costs and were insignificant during the periods presented.
	Use of estimates
	The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates used in the preparation of these financial statements include the assumptions used in determining the useful lives of long-lived assets, the assumptions used in determining whether assets are impaired, the assumptions used in determining the valuation allowance for deferred income tax assets and the assumptions used in stock based compensation awards. Actual results could differ from those estimates.
	2	SIGNIFICANT ACCOUNTING POLICIES (continued)
	Benefit plans
	The Company contributes to employee Registered Retirement Savings Plans in Canada and 401(k) plans in the United States.     Contributions are expensed as operating expenses when incurred. The Company made contributions of $1,569 in 2014, $1,533 in 2013 and $1,389 in 2012.
	Stock-based compensation
The Company recognizes compensation expense for all newly granted awards and awards modified, repurchased or cancelled based on fair value at the date of grant.
Financial instruments
The Company accounted for its two expired interest rate swap contracts on its term debt utilizing ASC 815 “Derivatives and Hedging”. All changes in the fair value of such swap contracts were recorded in earnings. The fair value of settlement costs, when the contracts were in place, were included in current liabilities on the consolidated balance sheets. No liability remains. Disclosure requirements of ASC 815 are disclosed in Note 22.
Fair value of financial instruments
ASC 820 “Fair Value Measurements and Disclosures” ("ASC 820") defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and establishes a hierarchy that categorizes and prioritizes the inputs to be used to estimate fair value. The three levels of inputs used are as follows:
Level 1 – Quoted prices in active markets for identical assets or liabilities.
Level 2 – Inputs other than Level 1 that are observable for the asset or liability, either directly or indirectly, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data by correlation or other means.
Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
The disclosure requirements of ASC 820 related to the Company’s financial assets and liabilities are presented in Note 22.

	RECENTLY ISSUED PRONOUNCEMENTS
	Disclosures about offsetting assets and liabilities
	In December 2011, the FASB issued ASU No. 2011-11, "Disclosures about offsetting assets and liabilities" ("ASU 2011-11"). ASU 2011-11 requires entities to disclose information about offsetting and related arrangements to enable users of financial statements to understand the effect of those arrangements on an entity's financial position. ASU 2011-11 requires enhanced disclosure by requiring improved information about financial instruments and derivative instruments that are either (i) offset in accordance with current literature or (ii) subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset in accordance with current literature. ASU 2011-11 is effective for fiscal years, and interim periods within those years, beginning on or after January 1, 2013. The Company adopted ASU 2010-11 as of April 1, 2013. Such adoption had no impact on the Company's consolidated financial statements.
	3.    RECENTLY ISSUED PRONOUNCEMENTS (continued)
	Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity
	In March 2013, the FASB issued ASU 2013-05 Topic 830 - Foreign Currency Matters (“ASU 2013-05”). ASU 2013-05 resolves the diversity in practice about whether Subtopic 810-10, Consolidation-Overall, or Subtopic 830-30, ASU 2013-05 applies to the release of the cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. In addition, the amendments in ASU 2013-05 resolve the diversity in practice for the treatment of business combinations achieved in stages (sometimes referred to as step acquisitions) involving a foreign entity. The amendments in ASU 2013-05 are effective prospectively for fiscal years (and interim reporting periods within those years) beginning after December 15, 2013. The Company does not expect the adoption of ASU 2013-05 to have a material effect on the Company's consolidated financial statements.
	Presentation of Unrecognized Tax Benefits
	In July 2013, the FASB issued ASU 2013-11, "Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss ("NOL") Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists" ("ASU 2013-11"). ASU 2013-11 requires an unrecognized tax benefit to be presented as a reduction to a deferred tax asset in the financial statements for an NOL carryforward, a similar tax loss, or a tax credit carryforward except in circumstances when the carryforward or tax loss is not available at the reporting date under the tax laws of the applicable jurisdiction to settle any additional income taxes or the tax law does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purposes. When those circumstances exist, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The new financial statement presentation provisions relating to this update are prospective and effective for interim and annual periods beginning after December 15, 2013, with early adoption permitted. The Company does not anticipate a material impact to its consolidated financial statements related to this guidance.

	Trade receivables are presented net of an allowance for doubtful accounts. The allowance was $58 as of March 31, 2014 and $49 as of March 31, 2013. The Company manages and evaluates the collectability of its trade receivables as follows: management reviews aged accounts receivable listings and contact is made with customers that have extended beyond agreed upon credit terms. Senior management and operations are notified so that when they are contacted by such customers for a future delivery, they can request that the customer pay any past due amounts before any future cargo is booked for shipment. Customer credit risk is also managed by reviewing the history of payments by the customer, the size and credit quality of the customer, the period of time remaining within the shipping season and demand for future cargos.

	The total provision (recovery) for income taxes differs from that amount which would be computed by applying the U.S. Federal and Canadian income tax rates to income (loss) before provision for income taxes as follows:
			Year ended					Year ended					Year ended
			March 31, 2014					March 31, 2013					March 31, 2012
	Statutory U.S. federal			34	%				34	%				34	%

	Foreign Statutory Rate Change			—	%				(5.7	)%				—	%
	Effective income tax rate			1526.30%					11.40%					-21.30%
	The primary reasons that the effective income tax rate for fiscal 2014 is higher than the statutory U.S. federal tax rate are the recognition of the full federal valuation allowance at March 31, 2014, the mix of income between jurisdictions and the comparative magnitude of the domestic permanent differences.

The Company has net long-term deferred tax liabilities of $638 ($2,203 net long-term deferred assets as of March 31, 2013) in United States federal and state jurisdictions and net long term deferred tax liabilities of $4,496 ($3,532 as of March 31, 2013) in Canadian jurisdictions. The Company establishes a valuation allowance when it is more likely than not that it will not be able to realize the benefit of the deferred tax assets, or when future deductibility is uncertain.  Periodically, the valuation allowance is reviewed and adjusted based on management’s assessment of realizable deferred tax assets.
The Company determined at March 31, 2013 that it was more likely than not that its deferred income tax assets would be realized while in a net deferred tax asset position based on the timing of the expected reversal of the deferred tax liabilities.
However, at March 31, 2014, the Company determined that its U.S. federal net deferred tax assets, including net operating loss carry-forwards, will not be utilized due to a cumulative break-even position over the past three fiscal years, coupled with anticipated cumulative three year losses in the near future. As such, the Company recorded a full valuation allowance against the U.S. Federal net deferred tax assets.
The Company determined that the Canadian deferred income tax asset relating to capital or non-capital losses on Lower Lakes Towing will be realized based on performance of the entity and the expected timing of the reversal of the deferred tax liabilities. The Company also determined that the Canadian deferred income tax assets on Lower Lakes Ship Repair, formed during the fiscal year ended March 31, 2013, will not be realized based on uncertainty of future income. As such, a full valuation allowance was recorded against Lower Lakes Ship Repair’s deferred tax assets.
The valuation allowance against the U.S. state deferred tax assets decreased by $47 for the fiscal year ended March 31, 2014, increased by $4 for the year ended March 31, 2013 and decreased by $37 for the fiscal year ended March 31, 2012.
At March 31, 2014, the Company had unused U.S. federal net operating loss carry-forwards totaling $46,085 that expire between fiscal 2020 and 2044, of which a small portion is subject to Internal Revenue Code section 382 annual limitations.  At March 31, 2014, the Company also had unused Canadian net operating loss carry-forwards totaling CDN $16,876 that expire between fiscal 2025 and 2033.

	CONTINGENCIES
	The Company is not involved in any legal proceedings which are expected to have a material effect on its business, financial position, results of operations or liquidity, nor is the Company aware of any proceedings that are pending or threatened which may have a material effect on the Company’s business, financial position, results of operations or liquidity.  From time to time, the Company may be subject to legal proceedings and claims in the ordinary course of business involving principally commercial charter party disputes, and claims for alleged property damages, personal injuries and other matters. Those claims, even if lacking merit, could result in the expenditure of significant financial and managerial resources.  It is expected that larger claims would be covered by insurance, subject to customary deductibles, if they involve liabilities that may arise from allision, other marine casualty, damage to cargoes, oil pollution, death or personal injuries to crew. The Company evaluates the need for loss accruals under the requirements of ASC 450 – Contingencies.  The Company records an estimated loss for any claim, lawsuit, investigation or proceeding when it is probable that a liability has been incurred and the amount of the loss can reasonably be estimated. If the reasonable estimate of a probable loss is a range, and no amount within the range is a better estimate, then the Company records the minimum amount in the range as the loss accrual. If a loss is not probable or a probable loss cannot be reasonably estimated, no liability is recorded. As of March 31, 2014 an accrual of $138 ($490 as of March 31, 2013) was recorded for various claims.  Management does not anticipate material variations in actual losses from the amounts accrued related to these claims.

	For all share-based compensation, as employees and directors render service over the vesting periods, expense is recorded in general and administrative expenses. Generally this expense is for the straight-line amortization of the grant date fair market value adjusted for expected forfeitures. Other paid-in capital is correspondingly increased as the compensation is recorded. Grant date fair market value for all non-option share-based compensation is the average of the high and low trading prices on the date of grant.
	18.    STOCKHOLDERS’ EQUITY (continued)
	The general characteristics of issued types of share-based awards granted under the LTIP through March 31, 2014 are as follows:
	Stock Awards - All of the shares issued to non-employee outside directors vest immediately.  The first award to non-employee outside directors in the amount of 12,909 shares was made on February 13, 2008 for services through March 31, 2008.  During the fiscal year ended March 31, 2009, the Company awarded 15,948 shares for services from April 1, 2008 through December 31, 2008. The Company awarded 37,144 shares during the fiscal year ended March 31, 2010 for services from January 1, 2009 through March 31, 2010. During the fiscal year ended March 31, 2011, the Company awarded 14,007 shares for services provided from April 1, 2010 through March 31, 2011. During the fiscal year ended March 31, 2012, the Company awarded 10,722 shares for services from April 1, 2011 to March 31, 2012. During the fiscal year ended March 31, 2013, the Company awarded 10,854 shares for services provided from April 1, 2012 to March 31, 2013. During the fiscal year ended March 31, 2014, the Company awarded 19,256 shares for the services rendered from April 1, 2013 to March 31, 2014. Grant date fair market value for all these awards is the average of the high and low trading prices of the Company’s common stock on the date of grant.
	On July 31, 2008, the Company’s Board of Directors authorized management to make payments effective as of that date to the participants in the management bonus program. Pursuant to the terms of the management bonus program, Rand issued 478,232 shares of common stock to such employee participants.
	Stock Options - Stock options granted to management employees vest over three years in equal annual installments. All options issued through March 31, 2014 expire ten years from the date of grant. Stock option grant date fair values are determined at the date of grant using a Black-Scholes option pricing model, a closed-form fair value model based on market prices at the date of grant. At each grant date the Company has estimated a dividend yield of 0%.  The weighted average risk free interest rate within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of the grant, which was 4.14% for the fiscal 2009 (July 2008) grant. Expected volatility for the fiscal 2009 grants was based on the prior 26 week period, which reflected trading and volume after the Company made major announcements on acquisitions and capital investments. Expected volatility was 39.49% for the fiscal 2009 grant. Options outstanding (479,785) at March 31, 2014, had a remaining weighted average contractual life of approximately four years.  The Company recorded compensation expenses of $Nil for the twelve month periods ended March 31, 2014 and March 31, 2013, respectively. All of the stock options granted in February 2008 (243,199) and July 2008 (236,586), had vested as of March 31, 2014.
	Shares issued under Employees’ Retirement Savings Plans - The Company issued an aggregate of 204,336 shares to the individual retirement plans of all eligible Canadian employees under the LTIP from July 1, 2009 through March 31, 2014.  The Canadian employees’ plans are managed by independent brokerages. These shares vested immediately but are subject to the Company’s Insider Trading Policy. The shares were issued using the fair value share price, as defined by the LTIP, as of the first trading day of each month for that previous period’s accrued expense. The Company granted $Nil of equity of such accrued compensation expense for each of the twelve month periods ended March 31, 2014 and March 31, 2013.
	Shares issued in lieu of cash compensation - The Company experienced a decrease in customer demand at the beginning of the 2009 sailing season and in an effort to maximize the Company’s liquidity, the Compensation Committee of the Company’s Board of Directors requested that five of the Company’s executive officers and all of its outside directors receive common stock as compensation in lieu of cash until the Company had better visibility about its outlook. As of November 16, 2009, the Company issued 158,325 shares to such officers and all of its outside directors at the average of the high and low trading prices Company’s common stock on the date of grant. The shares were issued under the LTIP and vested immediately. Beginning the third quarter of the fiscal year ended March 31, 2010, such executives and outside directors’ compensation reverted back to cash.
	18.    STOCKHOLDERS’ EQUITY (continued)
	On September 16, 2010, the Company issued 15,153 shares to a key executive for payment of the fiscal year 2010 bonus at the average of the high and low trading prices of the Company’s common stock on the date of grant. The shares were issued under the LTIP and vested immediately. On February 15, 2013, the Company issued 94,993 shares to eligible Canadian and U.S. employees for a bonus at the average of the high and low trading prices of the Company’s common stock on the date of grant. The shares were issued under the LTIP and vested immediately.

Financial Instruments [Abstract]	'
FINANCIAL INSTRUMENTS	'
	FINANCIAL INSTRUMENTS
	Fair value of financial instruments
	Financial instruments are comprised of cash and cash equivalents, accounts receivable, accounts payable, long-term debts, a deferred payment liability, accrued liabilities and bank indebtedness.  The estimated fair values of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate book values because of the short-term maturities of these instruments.  The estimated fair value of senior debt approximates the carrying value as the debt bears interest at variable interest rates, which are based on rates for similar debt with similar credit rates in the open market.  The subordinated note and deferred payment liabilities are valued based on the interest rate of similar debt in the open market.
	Fair value guidance establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. A financial asset's or liability's classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.
	The contract for two interest rate swaps that was entered into effective February 15, 2008, expired on March 31, 2013. The fair value adjustment of the interest rate swap contract resulted in a gain of $1,087 for the twelve month period ended March 31, 2013 and a gain of $771 for the twelve month period ended March 31, 2012. This gain was included in the Company’s earnings for the twelve month periods ended March 31, 2013 and March 31, 2012.
	Foreign exchange risk
	Foreign currency exchange risk to the Company results primarily from changes in exchange rates between the Company’s reporting currency, the U.S. Dollar, and the Canadian dollar.  The Company is exposed to fluctuations in foreign exchange as a significant portion of revenue and operating expenses are denominated in Canadian dollars.
	22	FINANCIAL INSTRUMENTS (continued)
	Interest rate risk
	The Company is exposed to fluctuations in interest rates as a result of its banking facilities and senior debt bearing variable interest rates.
	In December 2012, the Company entered into two interest rate cap contracts covering 50% of its outstanding term debt on the date of such contracts at a cap of three month Libor at 2.5% on its U.S. Term Debt borrowings and a cap of three month BA rates at 3.0% on its Canadian Term Debt borrowings. The notional amount on each of these instruments will decrease with each scheduled principal payment of the term loan under the Third Amended and Restated Credit Agreement. The interest rate cap contracts will terminate on December 1, 2015. Such contracts cover approximately 65% of first lien term debt as of March 31, 2014.
	The Company did not designate the two expired swap contracts for hedge accounting treatment and therefore changes in fair value of these contracts were recorded in earnings as follows:
	Derivatives not		Location of gain	Year ended March 31, 2014		Year ended March 31, 2013			Year ended March 31, 2012

			earnings
	Interest rate swap		Other (income) and expenses	$	—	$	(1,087	)	$	(771	)
	contracts liability
	Credit risk
	Accounts receivable credit risk is mitigated by the diversification of the Company’s customers among industries and the short shipping season.
	Liquidity risk
	The ongoing tightened credit in financial markets and continued general economic downturn may adversely affect the ability of the Company’s customers and suppliers to obtain financing for significant operations and purchases and to perform their obligations under agreements with the Company.  The tightening of credit could (i) result in a decrease in, or cancellation of, existing business, (ii) limit new business, (iii) negatively impact the Company’s ability to collect accounts receivable on a timely basis and (iv) affect the eligible receivables that are collateral for the Company’s lines of credit.  The Company makes seasonal net borrowings under its revolving credit facility during the first quarter of each fiscal year to fund working capital needed to commence the sailing season. Such borrowings are then reduced during the second half of each fiscal year.

Accounting Policies [Abstract]	'
Cash and cash equivalents	'
	Cash and cash equivalents
	The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents.
Accounts receivable and concentration of credit risk	'
	Accounts receivable and concentration of credit risk
	The majority of the Company’s accounts receivable are amounts due from customers and other accounts receivable, including insurance and Harmonized Sales Tax refunds.  The majority of accounts receivable are due within 30 to 60 days and are stated at amounts due from customers net of an allowance for doubtful accounts. The Company extends credit to its customers based upon its assessment of their creditworthiness and past payment history. Accounts outstanding longer than the contractual payment terms are considered past due. The Company has historically had no significant bad debts. Interest is not accrued on outstanding receivables.
Revenue and operating expenses recognition	'
	Revenue and operating expenses recognition
	The Company generates revenues from freight billings under contracts of affreightment (voyage charters) generally on a rate per ton basis based on origin-destination and cargo carried. Voyage revenue is recognized ratably over the duration of a voyage based on the relative transit time in each reporting period when the following conditions are met: the Company has a signed contract of affreightment, the contract price is fixed or determinable and collection is reasonably assured.  Included in freight billings are other fees such as fuel surcharges and other freight surcharges, which represent pass-through charges to customers for toll fees, lockage fees and ice breaking fees paid to other parties.  Fuel surcharges are recognized ratably over the duration of the voyage, while freight surcharges are recognized when the associated costs are incurred. Freight surcharges are less than 5% of total revenue.
	Marine operating expenses such as crewing costs, fuel, tugs and insurance are recognized as incurred or consumed and thereby are recognized ratably in each reporting period. Repairs and maintenance and certain other insignificant costs are recognized as incurred.
	The Company subcontracts excess customer demand to other freight providers.  Service to customers under such arrangements is transparent to the customer and no additional services are provided to customers.  Consequently, revenues recognized for customers serviced by freight subcontractors are recognized on the same basis as described above.  Costs for subcontracted freight providers, presented as “outside voyage charter fees” in the consolidated statements of operations, are recognized as incurred and therefore are recognized ratably over the voyage.
	The Company accounts for sales taxes imposed on its services on a net basis in the consolidated statements of operations.
	In addition, all revenues are presented on a gross basis.
Vessel acquisitions	'
	Vessel acquisitions
	Vessels are stated at cost, which consists of the purchase price and any material expenses incurred upon acquisition, such as initial repairs, improvements, delivery expenses and other expenditures to prepare the vessel for its initial voyage. Subsequent expenditures for conversions and major improvements are also capitalized when they appreciably extend the life, increase the earnings capacity or improve the efficiency or safety of the vessels. Significant financing costs incurred during the construction period of the vessels are also capitalized and included in the vessels' cost.
Fuel and lubricant inventories	'
	Fuel and lubricant inventories
	Raw materials, fuel and certain operating supplies are accounted for on a first-in, first-out cost method (based on monthly averages). Raw materials and fuel are stated at the lower of actual cost (first-in, first-out method) or market. Operating supplies are stated at actual cost or average cost.
Intangible assets and goodwill	'
	Intangible assets and goodwill
	Intangible assets consist primarily of goodwill, deferred financing costs, trademarks, trade names and customer relationships and contracts. Intangible assets are amortized as follows:
	Trademarks and trade names	10 years straight-line
	Customer relationships and contracts	15 years straight-line
	Deferred financing costs are amortized on a straight-line basis over the term of the related debt, which approximates the effective interest method.
Property and equipment	'
	Property and equipment
	Property and equipment are recorded at cost.  Depreciation methods for property and equipment are as follows:
	Vessels	5 - 25 years straight-line
	Leasehold improvements	7 - 11 years straight-line
	Vehicles	20% declining-balance
	Furniture and equipment	20% declining-balance
	Computer equipment	45% declining-balance
	Communication equipment	20% declining-balance
Impairment of fixed assets	'
	Impairment of fixed assets
	Fixed assets (e.g. property and equipment) and finite-lived intangible assets (e.g. customer lists) are tested for impairment upon the occurrence of a triggering event that indicates the carrying value of such an asset or asset group (e.g. tugs and barges), might be no longer recoverable. Examples of such triggering events include a significant disposal of a portion of such assets, an adverse change in the market involving the business employing the related asset(s), a significant decrease in the benefits realized from an acquired business, difficulties or delays in integrating the business, and a significant change in the operations of an acquired business.
	Once a triggering event has occurred, the recoverability test employed is based on whether the intent is to hold the asset(s) for continued use or to hold the asset(s) for sale. If the intent is to hold the asset(s) for continued use, the recoverability test involves a comparison of undiscounted cash flows excluding interest expense, against the carrying value of the asset(s) as an initial test. If the carrying value of such asset(s) exceeds the undiscounted cash flow, the asset(s) would be deemed to be impaired. Impairment would then be measured as the difference between the fair value of the fixed or amortizing intangible asset and the carrying value of such asset(s). The Company generally determines fair value by using the discounted cash flow method. If the intent is to hold the asset(s) for sale and certain other criteria are met (i.e. the asset(s) can be disposed of currently, appropriate levels of authority have approved the sale and there is an actively pursuing buyer), the impairment test is a comparison of the asset’s carrying value to its fair value less costs to sell. To the extent that the carrying value is greater than the asset’s fair value less costs to sell, an impairment loss is recognized for the difference. The Company has determined that there were no adverse changes in our markets or other triggering events that could affect the valuation of our assets during the twelve month period ended March 31, 2014.
Impairment of goodwill	'
	Impairment of goodwill
	The Company annually reviews the carrying value of goodwill to determine whether impairment may exist. Accounting Standards Codification (“ASC”) 350 “Intangibles-Goodwill and Other” and Accounting Standards Update (“ASU”) 2011-08 Intangibles—Goodwill and Other (Topic 350) - Testing Goodwill for Impairment requires that goodwill and certain intangible assets be assessed annually for impairment using fair value measurement techniques. Specifically, goodwill impairment is determined using a three-step process. The first step of the goodwill impairment test is to perform a qualitative assessment before calculating the fair value of the reporting unit when testing goodwill for impairment. If the fair value of the reporting unit is determined, based on qualitative factors, to be more likely than not less than the carrying amount of the reporting unit, then entities are required to perform the two-step goodwill impairment test. The second step of the goodwill impairment test is used to identify potential impairment by comparing the fair value of a reporting unit with its carrying amount, including goodwill. The estimates of fair value of the Company’s two reporting units, which are the Company’s Canadian and US operations (excluding the parent), are determined using various valuation techniques with the primary techniques being a discounted cash flow analysis and peer analysis. A discounted cash flow analysis requires various judgmental assumptions, including assumptions about future cash flows, growth rates, and discount rates. The assumptions about future cash flows and growth rates are based on the Company’s forecast and long-term estimates. Discount rate assumptions are based on an assessment of the risk inherent in the respective reporting units. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired and the second step of the impairment test is unnecessary. If the carrying amount of a reporting unit exceeds its fair value, the second step of the goodwill impairment test is performed to measure the amount of impairment loss, if any. The third step of the goodwill impairment test compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. If the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination. That is, the fair value of the reporting unit is allocated to all of the assets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination and the fair value of the reporting unit was the purchase price paid to acquire the reporting unit.  As of March 31, 2014, the Company conducted the qualitative assessment and determined that the fair value of its two reporting units exceeded their carrying amounts and the remaining two-step impairment testing was therefore not necessary.  The Company has determined that there were no adverse changes in our markets or other triggering events that indicated that it is more likely than not that the fair value of our reporting units was less than the carrying value of our reporting units during the twelve month period ended March 31, 2014.
Drydock costs	'
	Drydock costs
	Drydock costs incurred during statutory Canadian and United States certification processes are capitalized and amortized on a straight-line basis over the benefit period, which is generally 60 months. Drydock costs include costs of work performed by third party shipyards and subcontractors and other direct expenses to complete the mandatory certification process.
Repairs and maintenance	'
	Repairs and maintenance
	The Company’s vessels require repairs and maintenance each year to ensure the fleet is operating efficiently during the shipping season.  The majority of repairs and maintenance are completed in January, February, and March of each year when the vessels are inactive.  The Company expenses such routine repairs and maintenance costs.  Significant repairs to the Company’s vessels (whether owned or available to the Company under a time charter), such as major engine overhauls and major hull steel repairs, are capitalized and amortized over the remaining useful life of the upgrade or asset repaired, or the remaining lease term.
Income taxes	'
	Income taxes
	The Company accounts for income taxes in accordance with ASC 740 “Income Taxes”, which requires the determination of deferred tax assets and liabilities based on the differences between the financial statement and income tax bases of tax assets and liabilities, using enacted tax rates in effect for the year in which the differences are expected to reverse.  A valuation allowance is recognized, if necessary, to measure tax benefits to the extent that, based on available evidence, it is more likely than not that they will be realized.
	The Company classifies interest expense related to income tax liabilities, when applicable, as part of the interest expense in its consolidated statements of operations rather than income tax expense.  To date, the Company has not incurred material interest expenses or penalties relating to assessed taxation amounts.
	There is a current examination taking place by the U.S. taxing authorities for the financial year 2012 with no adjustments proposed as of the date of this Annual Report on Form 10-K. Lower Lakes was examined by the Canadian taxing authority for the tax years 2009 and 2010 and such examination is now complete.  This audit did not result in any material adjustments for such periods. The Company's primary U.S. state income tax jurisdictions are Illinois, Indiana, Michigan, Minnesota, Pennsylvania, Wisconsin and New York and its only international jurisdictions are Canada and its province of Ontario. The following table summarizes the open fiscal tax years for each major jurisdiction:
	Jurisdiction	Open Tax Years
	Federal (USA)	2010 – 2013

	The Company expenses all advertising costs as incurred. These costs are included in general and administrative costs and were insignificant during the periods presented.
Use of estimates	'
	Use of estimates
	The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates used in the preparation of these financial statements include the assumptions used in determining the useful lives of long-lived assets, the assumptions used in determining whether assets are impaired, the assumptions used in determining the valuation allowance for deferred income tax assets and the assumptions used in stock based compensation awards. Actual results could differ from those estimates.

Financial instruments	'
	Financial instruments
	The Company accounted for its two expired interest rate swap contracts on its term debt utilizing ASC 815 “Derivatives and Hedging”. All changes in the fair value of such swap contracts were recorded in earnings. The fair value of settlement costs, when the contracts were in place, were included in current liabilities on the consolidated balance sheets. No liability remains. Disclosure requirements of ASC 815 are disclosed in Note 22.
	Fair value of financial instruments
	ASC 820 “Fair Value Measurements and Disclosures” ("ASC 820") defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and establishes a hierarchy that categorizes and prioritizes the inputs to be used to estimate fair value. The three levels of inputs used are as follows:
	Level 1 – Quoted prices in active markets for identical assets or liabilities.
	Level 2 – Inputs other than Level 1 that are observable for the asset or liability, either directly or indirectly, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data by correlation or other means.
	Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	The disclosure requirements of ASC 820 related to the Company’s financial assets and liabilities are presented in Note 22.
