Organization Consolidation And Presentation Of Financial Statements [Abstract]
BASIS OF PRESENTATION	2. BASIS OF PRESENTATION The accompanying unaudited interim condensed consolidated financial statements (the “Financial Statements”) have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X and, accordingly, the Financial Statements do not include all of the information and notes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of the Company, the Financial Statements contain all adjustments necessary, consisting of only normal recurring adjustments, for a fair statement of its financial position as of March 31, 2021, and its results of operations and cash flows for the three months ended March 31, 2021 and 2020. The condensed balance sheet at December 31, 2020, was derived from audited annual financial statements but does not contain all of the footnote disclosures from the annual financial statements. These Financial Statements should be read in conjunction with the audited consolidated financial statements as of December 31, 2020 and 2019 and for each of the three years in the period ended December 31, 2020 included in the Annual Report on Form 10-K of the Company as filed with the U.S. Securities and Exchange Commission. As described in Note 4, the Company adopted a new accounting standard relating to convertible debentures effective January 1, 2021. Further information on this standard and the impact on the Company of this standard is described in Note 4. In these Financial Statements, unless otherwise indicated, all dollar amounts are expressed in United States (“U.S.”) dollars. DIRTT’s financial results are consolidated in Canadian dollars, the Company’s functional currency, and the Company has adopted the U.S. dollar as its reporting currency. All references to US$ or $ are to U.S. dollars and references to C$ are to Canadian dollars. Principles of consolidation The Financial Statements include the accounts of DIRTT and its subsidiaries. All intercompany balances, income and expenses, unrealized gains and losses and dividends resulting from intercompany transactions have been eliminated on consolidation. Basis of measurement These Financial Statements have been prepared on the historical cost convention except for certain financial instruments and certain components of stock-based compensation that are measured at fair value. Historical cost is generally based on the fair value of the consideration given in exchange for assets. The Company’s quarterly tax provision is based upon an estimated annual effective tax rate. Seasonality Sales of the Company’s products are driven by consumer and industrial demand for interior construction solutions. The timing of customer’s construction projects can be influenced by a number of factors including the prevailing economic climate and weather.

COVID-19

Accounting Changes And Error Corrections [Abstract]
COVID-19	3. COVID-19 On March 11, 2020, COVID-19 was declared a global pandemic by the World Health Organization and has had extraordinary and rapid negative impacts on global societies, workplaces, economies and health systems. The resulting adverse economic conditions have negatively impacted construction activity and consequently DIRTT’s business, with potential significant negative impacts extending to the first half of 2021 and beyond. While many construction sites remain open and re-opening strategies have been implemented across North America, certain projects have experienced delays, impacted by both the implementation of social distancing and other safety-related measures and the re-emergence of COVID-19 in certain geographic areas. It is not possible to predict the timing and pace of economic recovery, or the resumption of delayed construction activity and related demand, nor is it possible to predict the impact of such developments on the Company’s ability to achieve its business objectives. COVID-19 has increased the complexity of estimates and assumptions used to prepare the Company’s consolidated financial statements and the following key sources of estimation uncertainty: Credit risk COVID-19 may cause DIRTT’s Distribution Partners and customers to experience liquidity issues and this may result in higher expected credit losses or slower collections. Management estimated the impact of expected credit losses and increased the provision by $0.6 million in the first quarter of 2020 (see Note 5). Management has continued to reassess the impact of COVID-19 on our Distribution Partners. The estimation of such credit losses is complex because of limited historical precedent for the current economic situation. In addition, the Company acquired trade credit insurance effective April 1, 2020. Liquidity risk The Company may have lower cash flows from operating activities available to service debts due to lower sales or collections. To address this risk and the uncertainty around the timing of a recovery, the Company issued convertible unsecured subordinated debentures in January 2021, for net proceeds of $29.5 million, and has credit facilities available as described in Note 6. Government subsidies As part of the Canadian federal government’s COVID-19 Economic Response Plan, the Canadian government established the Canadian Emergency Wage Subsidy (“CEWS”). The CEWS provides the Company with a taxable subsidy in respect of a specific portion of wages paid to Canadian employees during qualifying periods extending from March 15, 2020 to June 5, 2021 (with an extension to September 25, 2021 having been announced in the 2021 Canadian federal budget), based on the percentage decline of the Company in certain of its Canadian-sourced revenues during each qualifying period. Pursuant to proposed changes announced in the 2021 Canadian federal budget, the Company may be required to repay all or a portion of the CEWS amounts for any qualifying period commencing after June 5, 2021 where the aggregate compensation for specified executives during the 2021 calendar year exceeds the aggregate compensation for specified executives during the 2019 calendar year. The Company’s eligibility for the CEWS may change for each qualifying period and is reviewed by the Company for each qualifying period. On November 19, 2020, the Canadian government also implemented the Canada Emergency Rent Subsidy (“CERS”). The CERS provides a taxable subsidy to cover eligible expenses for qualifying properties, subject to certain maximums, starting on September 27, 2020 to June 5, 2021 (with an extension to September 25, 2021 having been announced in the 2021 Canadian federal budget), with the amount of the subsidy based on the percentage decline of the Company in certain of its Canadian-sourced revenues in each qualifying period. The Company’s eligibility for the CERS may change for each qualifying period and is reviewed by the Company for each qualifying period. Impairment At March 31, 2021, management determined an impairment provision was not required as our outlook is consistent with the assumptions used in our impairment test undertaken at December 31, 2021. In future periods, if our results or outlook are less than our forecast, this conclusion may need to be revisited.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
ADOPTION OF NEW AND REVISED ACCOUNTING STANDARDS	4. ADOPTION OF NEW AND REVISED ACCOUNTING STANDARDS On August 5, 2020, the Financial Accounting Standards Board issued Accounting Standards Update No. 2020-06, “Debt – Debt with Conversion and other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40)” The Company early adopted this standard on January 1, 2021. The Company had no convertible debt instruments outstanding at December 31, 2020 and the convertible unsecured subordinated debentures issued in January 2021 have been evaluated under this new guidance and there were no other transitional impacts to consider. Although there are several other new accounting standards issued or proposed by the Financial Accounting Standards Board, which the Company has adopted or will adopt, as applicable, the Company does not believe any of these accounting pronouncements has had or will have a material impact on its Financial Statements.

TRADE AND OTHER RECEIVABLES

Receivables [Abstract]
TRADE AND OTHER RECEIVABLES	5. TRADE AND OTHER RECEIVABLES Accounts receivable are recorded at the invoiced amount, do not require collateral and do not bear interest. The Company estimates an allowance for credit losses using the lifetime expected credit loss at each measurement date taking into account historical credit loss experience as well as forward-looking information in order to establish rates for each class of financial receivable with similar risk characteristics. Adjustments to this estimate are recognized in the statement of operations. In order to manage and assess our risk, management maintains credit policies that include regular review of credit limits of individual receivables and systematic monitoring of aging of trade receivables and the financial wellbeing of our customers. At March 31, 2021, approximately 85% of our trade accounts receivable are insured, relating to accounts receivables from counterparties deemed creditworthy by the insurer and excluding accounts receivable from government entities, that have arisen since April 1, 2020 when the trade credit insurance became effective. Our trade balances are spread over a broad Distribution Partner base, which is geographically dispersed. For the three months ended March 31, 2021, one Distribution Partner (2020 – none) accounted for $3.6 million of revenue, which is greater than 10% of total revenue. In addition, and where possible, we collect a 50% deposit on sales, excluding government and certain other clients. The Company’s aged receivables were as follows : As at March 31, December 31, 2021 2020 Current 12,362 12,500 Overdue 1,074 1,211 13,436 13,711 Less: expected credit losses (588 ) (588 ) 12,848 13,123 Sales tax receivable 302 242 Government subsidies receivable 2,254 1,743 Income tax receivable 3,845 3,845 19,249 18,953 Due to the uncertainties associated with the COVID-19 pandemic as well as the disruption to businesses in North America, the overall credit quality of certain receivables declined at March 31, 2020 compared to January 1, 2020. As a result of this consideration and the Company’s ongoing review of the credit quality of receivables, expected credit losses were increased by $0.6 million during the quarter ended March 31, 2020. No adjustments to our expected credit losses were required at March 31, 2021. During the first quarters of 2021 and 2020, no receivables were written off. Receivables are generally considered to be past due when over 60 days old unless there is a separate payment arrangement in place for the collection of the receivable.

Under the RBC Facility, the Company is able to borrow up to a maximum of 90% of investment grade or insured accounts receivable plus 85% of eligible accounts receivable plus the lesser of 75% of the book value of eligible inventory and 85% of the net orderly liquidation value of eligible inventory less any reserves for potential prior ranking claims (the “Borrowing Base”). At March 31, 2021, available borrowings are C$9.4 million ($7.5 million), of which no amounts have been drawn. Interest is calculated at the Canadian or U.S. prime rate plus 30 basis points or at the Canadian Dollar Offered Rate or LIBOR plus 155 basis points. Under the RBC Facility, if the Aggregate Excess Availability, defined as the Borrowing Base less any loan advances or letters of credit or guarantee and if undrawn including unrestricted cash, is less than C$5.0 million, the Company is subject to a fixed charge coverage ratio (“FCCR”) covenant of 1.10:1 on a trailing twelve month basis. Additionally, if the FCCR has been below 1.10:1 for the 3 immediately preceding months, the Company is required to maintain a reserve account equal to the aggregate of one year of payments on outstanding loans on the Leasing Facilities (defined below). The Company did not me e t the 3 month FCCR requirement during the first quarter of 2021 which result ed in requiring the restriction of $ 1.1 million of cash . Should an event of default occur or the Aggregate Excess Availability be less than C $ 6.25 million for 5 consecutive business days, the Company would enter a cash dominion period whereby the Company’s bank accounts would be blocked by RBC and daily balances will set-off any borrowings and any remaining amounts made available to the Company. Leasing Facilities The Company has a C$5.0 million equipment leasing facility in Canada (the “Canada Leasing Facility”) and a $14.0 million equipment leasing facility in the United States (the “U.S. Leasing Facility” and, together with the Canada Leasing Facility, the “Leasing Facilities”) with RBC, and one of its affiliates, which are available for equipment expenditures and certain equipment expenditures already incurred. The Leasing Facilities, respectively, have seven and five-year six-year During the first quarter of 2021, the Company received $nil (twelve months ended December 31, 2020: $3.5 million) of cash consideration under the U.S. Leasing Facility. Subsequent to March 31, 2021, we completed a $7.2 million Convertible Debentures On January 25, 2021, the Company completed a C$35.0 million bought-deal financing of convertible unsecured subordinated debentures (the “Debentures”) with a syndicate of underwriters. On January 29, 2021, the Company issued a further C$5.25 million of Debentures under the terms of an overallotment option granted to the underwriters. The Debentures will mature and be repayable on January 31, 2026 (the “Maturity Date”), unless earlier redeemed, repurchased or converted. The Debentures accrue interest at the rate of 6.00% per annum payable semi-annually in arrears on the last day of January and July of each year commencing on July 31, 2021. The Debentures are convertible into common shares of DIRTT, at the option of the holder, at any time prior to the close of business on the business day prior to the earlier of the Maturity Date and the date specified by the Company for redemption of the Debentures at a conversion price of C$4.65 per common share, being a ratio of approximately 215.0538 common shares per C$1,000 principal amount of Debentures. The conversion rate is subject to adjustment if certain corporate events occur prior to the Maturity Date. The net proceeds from the sale of the Debentures were C$37.6 million ($29.5 million), after deducting C$2.7 million of transaction costs which includes the underwriters’ commission and directly attributable professional fees. The Company accounted for the Debentures as a liability as the Debentures meet the definition of traditional convertible debt and there are no embedded derivatives requiring bifurcation. The Debentures are shown on the consolidated balance sheet in long-term debt. Interest expense was determined using the effective interest rate method with an effective interest rate of 7.5%. The contractual interest expense for the Debentures during the three months ended March 31, 2021 The Debentures are not redeemable by the Company before January 31, 2024 , except in certain limited circumstances following a change of control. On and after January 31, 2024 and prior to January 31, 2025, provided that the current market price of our common shares at the time at which notice of redemption is given is at least 125 % of the conversion price, the Debentures may be redeemed by the Company, in whole or in part from time to time, at our option on not more than 60 days ’ and not less than 30 days ’ prior written notice, for an amount equal to the principal amount thereof plus accrued and unpaid interest thereon . On and after January 31, 2025 and prior to the Maturity Date, the Debentures may be redeemed by the Company, in whole or in part from time to time, at our option on not more than 60 days ’ and not less than 30 days ’ prior written notice, for an amount equal to the principal amount thereof plus accrued and unpaid interest thereon .

INCOME TAXES	10. INCOME TAXES As at March 31, 2021, the Company recorded a valuation allowance of C$3.6 million ($2.8 million) against deferred tax assets (“DTAs”) incurred during the quarter in its Canadian entity as the Company’s Canadian entity has experienced cumulative losses in recent years (December 31, 2020 – C$6.6 million or $5.2 million). Although earnings were positive in 2019, ongoing near-term uncertainties on the business caused by the COVID-19 pandemic and the related decline in business activity impacted the Canadian entity’s ability to generate earnings. Accordingly, it is not more likely than not that the Canadian entity’s DTAs will be utilized in the near term.
