Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated balance sheet as of March 31, 2016 , the unaudited condensed consolidated statements of operations and comprehensive income for the three months ended March 31, 2016 and 2015 , and the unaudited condensed consolidated statements of cash flows for the three months ended March 31, 2016 and 2015 , have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by generally accepted accounting principles in the U.S. ("GAAP") can be condensed or omitted. The condensed consolidated balance sheet as of December 31, 2015 has been derived from the Company’s audited financial statements, which are included in its 2015 Annual Report on Form 10-K, filed with the SEC on February 26, 2016 . The unaudited condensed consolidated interim financial statements should be read in conjunction with the Company’s audited consolidated financial statements in its Annual Report on Form 10-K, for the year ended December 31, 2015 . The unaudited condensed consolidated interim financial statements include all adjustments necessary for the fair presentation of its consolidated results of operations, financial position, comprehensive income and cash flows. Results for the interim periods are not necessarily indicative of results to be expected for the full year or any other future periods. The unaudited condensed consolidated interim financial statements include Core-Mark and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in the unaudited condensed consolidated interim financial statements. Concentration of Credit Risks Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash investments, accounts receivable and other receivables. The Company places its cash and cash equivalents in short-term instruments with high quality financial institutions and limits the amount of credit exposure in any one financial instrument. The Company pursues amounts and incentives due from vendors in the normal course of business and is often allowed to deduct these amounts and incentives from payments made to vendors. A credit review is completed for new customers and ongoing credit evaluations of each customer’s financial condition are performed periodically, with reserves maintained for potential credit losses. Credit limits given to customers are based on a risk assessment of their ability to pay and other factors. Accounts receivable are typically not collateralized, but the Company may require prepayments or other guarantees whenever deemed necessary. Alimentation Couche-Tard, Inc. (“Couche-Tard”), the Company’s largest customer, accounted for approximately 12.4% and 14.5% of the Company’s total net sales in the three months ended March 31, 2016 and March 31, 2015 , respectively. Couche-Tard accounted for approximately 12.6% of the Company's total net accounts receivable as of March 31, 2016 . No single customer accounted for 10% or more of the Company’s accounts receivables as of December 31, 2015 . Recent Accounting Standards or Updates Not Yet Effective On May 28, 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09 ("ASU 2014-09"), Revenue from Contracts with Customers: Topic 606 (“ASU 2014-09”), to supersede nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. This standard is effective for the Company beginning in 2018 and allows for either full retrospective adoption or modified retrospective adoption with cumulative effect recognized at the date of initial adoption. Earliest adoption of this standard is permitted for Core-Mark beginning in 2017. The Company is currently evaluating the impact of the adoption of ASU 2014-09 on its consolidated financial statements. On January 5, 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities: Subtopic 825-10 (“ASU 2016-01”). The new guidance enhances the reporting model for financial instruments, which includes amendments to address aspects of recognition, measurement, presentation and disclosure. ASU 2016-01 is effective for annual periods beginning after December 15, 2017. The Company is currently evaluating the impact ASU 2016-01 will have on its consolidated financial statements. On February 25, 2016, the FASB issued ASU No. 2016-02, Leases: Topic 842 (“ASU 2016-02”), which supersedes existing lease guidance. The new guidance increases transparency by requiring lessees to recognize right-of-use assets and corresponding lease liabilities on the balance sheet. This standard is effective for annual periods beginning after December 15, 2018, although early adoption is permitted. The Company is currently evaluating the impact ASU 2016-02 will have on its consolidated financial statements. On March 30, 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation: Improvements to Employee Share-Based Payment Accounting: Topic 718 (“ASU 2016-09”). The new guidance simplifies several aspects of how companies account for share-based compensation, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statements of cash flows. ASU 2016-09 is effective for annual periods beginning after December 15, 2016, although early adoption is permitted. The Company is currently evaluating the impact ASU 2016-09 will have on its consolidated financial statements.

Inventories

Inventory Disclosure [Abstract]
Inventories	Inventories Inventories consist of the following (in millions): March 31, December 31, Inventories at FIFO, net of reserves $ 509.9 $ 524.6 Less: LIFO reserve (120.6 ) (117.2 ) Total inventories at LIFO, net of reserves $ 389.3 $ 407.4 Cost of goods sold reflects the application of the last-in, first-out (“LIFO”) method of valuing inventories in the U.S. based upon estimated annual producer price indices. Inventories in Canada are valued on a first-in, first-out (“FIFO”) basis, as LIFO is not a permitted inventory valuation method in Canada. During periods of rising prices, the LIFO method of costing inventories generally results in higher current costs being charged against income while lower costs are retained in inventories. Conversely, during periods of decreasing prices, the LIFO method of costing inventories generally results in lower current costs being charged against income and higher stated inventories. If the FIFO method had been used for valuing inventories in the U.S., inventories would have been approximately $120.6 million and $117.2 million higher for the period ended March 31, 2016 and December 31, 2015, respectively. The Company recorded LIFO expense of $3.4 million and $2.4 million for the three months ended March 31, 2016 and 2015 , respectively.

Debt Disclosure [Abstract]
Long-term Debt	Long-term Debt Long-term debt consists of the following (in millions): March 31, December 31, Amounts borrowed (Credit Facility) $ 15.0 $ 47.0 Obligations under capital leases 13.0 13.4 Total long-term debt $ 28.0 $ 60.4 The Company has a revolving credit facility (“Credit Facility”) with a capacity of $300 million , as of March 31, 2016 . The Credit Facility has an expansion feature which can be increased up to an additional $100 million limited by a borrowing base primarily consisting of eligible accounts receivable and inventories. All obligations under the Credit Facility are secured by first priority liens on substantially all of the Company’s present and future assets. The terms of the Credit Facility permit prepayment without penalty at any time (subject to customary breakage costs with respect to LIBOR or CDOR based loans prepaid prior to the end of an interest period). On May 21, 2015 , the Company entered into a sixth amendment to the Credit Facility (the "Sixth Amendment"), which extended the term of the Credit Facility from May 2018 to May 2020 . The Sixth Amendment fixed the unused facility fee at 25 basis points and provided for quarterly borrowing base reporting. The margin added to the LIBOR or CDOR rate remains at a range of 125 to 175 basis points. In addition, the Sixth Amendment raised and reset the baskets for stock repurchases in aggregate of $75.0 million , not to exceed $20.0 million in any year, an aggregate of $100.0 million for dividends and up to $150.0 million for permitted acquisitions. As of March 31, 2016 , the remaining balances under the Credit Facility for stock repurchases, dividends, and permitted acquisitions were $70.1 million , $86.6 million , and $150.0 million , respectively. On January 11, 2016 , the Company entered into a seventh amendment to the Credit Facility (the "Seventh Amendment"), which increased its Credit Facility from $200 million to $300 million . The Seventh Amendment also includes an expansion feature that gives the Company the option to increase the size of the Credit Facility to a total of $400 million , if exercised. The Company incurred fees of approximately $0.3 million in connection with the Seventh amendment. Amounts borrowed, outstanding letters of credit and amounts available to borrow, net of certain reserves required under the Credit Facility, were as follows (in millions): March 31, December 31, Amounts borrowed $ 15.0 $ 47.0 Outstanding letters of credit 17.4 18.5 Amounts available to borrow (1) 254.7 123.9 ______________________________________________ (1) Excluding $100 million expansion feature. Average borrowings during the three months ended March 31, 2016 and March 31, 2015 , were $78.1 million and $30.4 million , respectively, with amounts borrowed at any one time outstanding ranging from $10.0 million to $200.0 million . The weighted-average interest rate on the revolving credit facility for the three months ended March 31, 2016 was 1.8% compared to 1.7% for the same period in 2015 . The weighted-average interest rate is calculated based on the daily cost of borrowing, reflecting a blend of prime and LIBOR rates. The Company paid fees for unused facility and letter of credit participation, which are included in interest expense, of $0.2 million during the three months ended March 31, 2016 , and 2015 , respectively. The Company recorded charges related to amortization of debt issuance costs, which are included in interest expense, of less than $0.1 million for each of the three months ended March 31, 2016 and 2015 . Unamortized debt issuance costs were $1.5 million and $1.2 million as of March 31, 2016 and December 31, 2015 , respectively.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Litigation On March 18, 2016 , the Company and its insurers entered into a settlement agreement terminating appeals and ending the lawsuit against Sonitrol Corporation, which arose from the December 21, 2002 arson fire at the Denver warehouse, in which Sonitrol failed to detect and respond to a four-hour burglary and subsequent arson. On April 11, 2014 a jury awarded $2.75 million plus interest in favor of the Company and its insurers, which was subsequently upheld by the Appellate Court. In accordance with the settlement, the Company recognized a gain of $2.0 million , net of legal fees, which is included in selling general and administrative expenses for the quarter ended March 31, 2016. The Company is subject to certain legal proceedings, claims, investigations and administrative proceedings in the ordinary course of its business. The Company records a provision for a liability when it is both probable that the liability has been incurred and the amount of the liability can be reasonably estimated. These provisions, if any, are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case. In the opinion of management, the outcome of pending litigation is not expected to have a material effect on the Company’s results of operations or financial condition.

Income Taxes

Income Taxes	3 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s effective tax rate was 38.0% for the three months ended March 31, 2016 , compared to 39.6% for the same period in 2015 . The March 31, 2016 effective tax rate is lower than the comparable period in 2015 due primarily to tax credits claimed in the current year that were not available until the fourth quarter of last year. The total gross amount of unrecognized tax benefits related to federal, state and foreign taxes was approximately $0.4 million at both March 31, 2016 and December 31, 2015 , all of which would impact the Company’s effective tax rate, if recognized. The expiration of the statute of limitations for certain tax positions in future years could impact the total gross amount of unrecognized tax benefits by $ 0.2 million through March 31, 2017. The Company files U.S. federal, state and foreign income tax returns in jurisdictions with varying statutes of limitations. The 2012 to 2015 tax years remain subject to examination by federal and state authorities. The 2011 tax year is still open for certain state tax authorities. The 2008 to 2015 tax years remain subject to examination by the tax authorities in Canada.

Compensation and Retirement Disclosure [Abstract]
Employee Benefit Plans	Employee Benefit Plans The Company sponsored a qualified defined-benefit pension plan and a post-retirement benefit plan (collectively, “the Pension Plans”). The plans were frozen as of September 30, 1986, and since then there have been no new entrants to the Pension Plans. The following table provides the components of the net periodic benefit cost (income) of the qualified defined-benefit pension plan (in millions): Three Months Ended March 31, 2016 2015 PENSION BENEFITS Interest cost $ 0.3 $ 0.4 Expected return on plan assets (0.5 ) (0.5 ) Amortization of net actuarial loss 0.2 0.1 Net periodic benefit cost (income) $ — $ — The Company incurred less than $0.1 million in net periodic benefit costs related to the post-retirement benefit plan for the three months ended March 31, 2016 and 2015 . The Company made no contributions to the Pension Plans during the three months ended March 31, 2016 and March 31, 2015. No minimum contribution to the defined-benefit pension plan is required in 2016 . During the remainder of 2016 , the Company expects to contribute a total of $0.2 million to the post-retirement benefit plan. The Company offers certain plan participants the option to receive a lump sum payment in lieu of future annuity pension benefits. As a result, the Company expects that it will remeasure its pension plan obligation and record a settlement charge once the lump sum payments exceed thresholds calculated under GAAP. The Company expects to recognize settlement charges ranging between $0.8 million and $1.7 million in 2016 related to lump sum payments and other pension settlement activities.

Subsequent Events [Abstract]
Subsequent Event	Subsequent Event Acquisition of Pine State Convenience On April 22, 2016 , the Company signed a definitive agreement to acquire substantially all of the assets of Pine State Convenience, a division of Pine State Trading Company ("Pine State"), located in Gardiner, Maine. The purchase price is expected to be approximately $112.0 million predicated on the value of certain assets to be determined at closing. The closing is subject to regulatory approvals, including Hart-Scott-Rodino Act and applicable state licensing requirements for the sale of tobacco and other regulated products. The Company expects to incur approximately $3.1 million in start-up, due diligence and conversion costs in connection with the transaction. In the event the transaction is not completed due to the inability to obtain antitrust clearance, the Company could be required to pay Pine State a termination fee of approximately $4.0 million in certain circumstances.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting	Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated balance sheet as of March 31, 2016 , the unaudited condensed consolidated statements of operations and comprehensive income for the three months ended March 31, 2016 and 2015 , and the unaudited condensed consolidated statements of cash flows for the three months ended March 31, 2016 and 2015 , have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by generally accepted accounting principles in the U.S. ("GAAP") can be condensed or omitted. The condensed consolidated balance sheet as of December 31, 2015 has been derived from the Company’s audited financial statements, which are included in its 2015 Annual Report on Form 10-K, filed with the SEC on February 26, 2016 . The unaudited condensed consolidated interim financial statements should be read in conjunction with the Company’s audited consolidated financial statements in its Annual Report on Form 10-K, for the year ended December 31, 2015 . The unaudited condensed consolidated interim financial statements include all adjustments necessary for the fair presentation of its consolidated results of operations, financial position, comprehensive income and cash flows. Results for the interim periods are not necessarily indicative of results to be expected for the full year or any other future periods.
Principles of Consolidation	The unaudited condensed consolidated interim financial statements include Core-Mark and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in the unaudited condensed consolidated interim financial statements.
Concentration of Credit Risk	Concentration of Credit Risks Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash investments, accounts receivable and other receivables. The Company places its cash and cash equivalents in short-term instruments with high quality financial institutions and limits the amount of credit exposure in any one financial instrument. The Company pursues amounts and incentives due from vendors in the normal course of business and is often allowed to deduct these amounts and incentives from payments made to vendors. A credit review is completed for new customers and ongoing credit evaluations of each customer’s financial condition are performed periodically, with reserves maintained for potential credit losses. Credit limits given to customers are based on a risk assessment of their ability to pay and other factors. Accounts receivable are typically not collateralized, but the Company may require prepayments or other guarantees whenever deemed necessary.
Recent Accounting Standards or Updates Not Yet Effective	Recent Accounting Standards or Updates Not Yet Effective On May 28, 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09 ("ASU 2014-09"), Revenue from Contracts with Customers: Topic 606 (“ASU 2014-09”), to supersede nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. This standard is effective for the Company beginning in 2018 and allows for either full retrospective adoption or modified retrospective adoption with cumulative effect recognized at the date of initial adoption. Earliest adoption of this standard is permitted for Core-Mark beginning in 2017. The Company is currently evaluating the impact of the adoption of ASU 2014-09 on its consolidated financial statements. On January 5, 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities: Subtopic 825-10 (“ASU 2016-01”). The new guidance enhances the reporting model for financial instruments, which includes amendments to address aspects of recognition, measurement, presentation and disclosure. ASU 2016-01 is effective for annual periods beginning after December 15, 2017. The Company is currently evaluating the impact ASU 2016-01 will have on its consolidated financial statements. On February 25, 2016, the FASB issued ASU No. 2016-02, Leases: Topic 842 (“ASU 2016-02”), which supersedes existing lease guidance. The new guidance increases transparency by requiring lessees to recognize right-of-use assets and corresponding lease liabilities on the balance sheet. This standard is effective for annual periods beginning after December 15, 2018, although early adoption is permitted. The Company is currently evaluating the impact ASU 2016-02 will have on its consolidated financial statements. On March 30, 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation: Improvements to Employee Share-Based Payment Accounting: Topic 718 (“ASU 2016-09”). The new guidance simplifies several aspects of how companies account for share-based compensation, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statements of cash flows. ASU 2016-09 is effective for annual periods beginning after December 15, 2016, although early adoption is permitted. The Company is currently evaluating the impact ASU 2016-09 will have on its consolidated financial statements.
