Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Reporting for Consolidated Financial Statements	1. Basis of Reporting for Consolidated Financial Statements The accompanying unaudited condensed consolidated financial statements of CECO Environmental Corp. and its subsidiaries (the “Company”, “we”, “us”, or “our”) have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in annual financial statements have been condensed or omitted pursuant to those rules and regulations. In the opinion of management, the accompanying unaudited condensed consolidated financial statements of the Company contain all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the financial position as of March 31, 2020 and the results of operations, cash flows and shareholders’ equity for the three-month periods ended March 31, 2020 and 2019. The results of operations for the three-month period ended March 31, 2020 are not necessarily indicative of the results to be expected for the full year. The balance sheet as of December 31, 2019 has been derived from the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 as filed with the SEC. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. These financial statements and accompanying notes should be read in conjunction with the audited financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 filed with the SEC. Unless otherwise indicated, all balances within tables are in thousands, except per share amounts. COVID-19 On January 30, 2020, the World Health Organization (“WHO”) announced a global health emergency because of a new strain of coronavirus (“COVID-19”) originating in Wuhan, China and the risks to the international community as the virus spreads globally beyond its point of origin. On March 11, 2020, the WHO classified the COVID-19 outbreak as a pandemic, based on the rapid increase in exposure globally. The pandemic has had a significant impact on macroeconomic conditions and the end markets of our business. The Company has instituted some and may take additional temporary precautionary measures to comply with government directives and guidelines and minimize business disruption. The Company considered the impact of COVID-19 on the assumptions and estimates used and determined that there were no material adverse impacts on the Company’s results of operations and financial position at March 31, 2020. On March 27, 2020, President Trump signed into law the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”). The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer side social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. It is currently unclear if and how the Company will benefit from the CARES Act in the future, but we continue to examine the impacts the CARES Act may have on our business, results of operations, financial condition or liquidity. The full impact of the COVID-19 outbreak continues to evolve as of the date of this filing. As such, it is uncertain as to the full magnitude that the pandemic will have on the Company’s financial condition, liquidity, and future results of operations. Management is actively monitoring the impact of the global situation on its financial condition, liquidity, operations, suppliers, industry, and workforce. Given the daily evolution of the COVID-19 outbreak and the global responses to curb its spread, the Company is not able to estimate the effects of the COVID-19 outbreak on its results of operations, financial condition, or liquidity for fiscal year 2020.

Accounting Changes And Error Corrections [Abstract]
New Financial Accounting Pronouncements	2. New Financial Accounting Pronouncements Accounting Standards adopted in Fiscal 2020 None. Accounting Standards Yet to be Adopted In August 2018, the FASB issued ASU 2018-14, “Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans,” that makes minor changes to the disclosure requirements for employers that sponsor defined benefit pension and/or other postretirement benefit plans. The new guidance eliminates requirements for certain disclosures that are no longer considered cost beneficial and requires new ones that the FASB considers pertinent. ASU 2018-14 is effective for the Company January 1, 2021. The Company is evaluating the impact of the adoption of ASU 2018-14 on its consolidated financial statements.

Amortization over the next five years for finite life intangibles is expected to be $5.1 million for the remainder of 2020, $5.7 million in 2021, $4.8 million in 2022, $4.0 million in 2023, and $3.4 million in 2024. During the three-month period ended March 31, 2019, the Company reassessed the useful lives of certain tradenames and determined that $3.9 million of their tradenames would have useful lives of 10 years now versus indefinite. The Company completes an annual (or more often if circumstances require) goodwill and indefinite life intangible asset impairment assessment on October 1. As a part of its impairment assessment, the Company first qualitatively assesses whether current events or changes in circumstances lead to a determination that it is more likely than not (defined as a likelihood of more than 50 percent) that the fair value of a reporting unit or indefinite life intangible asset is less than its carrying amount. If there is a qualitative determination that the fair value is more likely than not greater than carrying value, the Company does not need to quantitatively test for impairment. If this qualitative assessment indicates a more likely than not potential that the asset may be impaired, the estimated fair value is calculated. If the estimated fair value is less than carrying value, an impairment charge is recorded. In 2019, we performed a quantitative assessment and concluded each of our reporting units and indefinite life intangible assets had excess fair value over their carrying value. However, as of March 31, 2020, we observed negative macroeconomic indicators resulting from the COVID-19 pandemic, which could have a direct impact on our business. We determined this constituted a triggering event that required an assessment to determine if an impairment loss may have occurred. Therefore, we qualitatively assessed whether it was more likely than not that goodwill and indefinite life intangible assets were impaired as of March 31, 2020. We reviewed our previous forecasts and assumptions based on our current projections, which are subject to various risks and uncertainties, including projected revenue, projected operational profit, terminal growth rates, and the cost of capital. Based on our interim impairment assessment as of March 31, 2020, we have determined that our goodwill and indefinite life intangible assets are not impaired. The Company’s assumptions about future conditions important to its assessment of potential impairment of its goodwill and indefinite life intangible assets, including the impacts of the COVID-19 pandemic, are subject to uncertainty, and the Company will continue to monitor these conditions in future periods as new information becomes available, and will update its analyses accordingly.

The fair value of the restricted stock units was determined by using the value of stock in the open market on the date of grant. The fair value of the stock-based awards granted is recorded as compensation expense on a straight-line basis over the vesting periods of the awards.

Compensation And Retirement Disclosure [Abstract]
Pension and Employee Benefit Plans	1 0 . Pension and Employee Benefit Plans We sponsor a non-contributory defined benefit pension plan for certain union employees. The plan is funded in accordance with the funding requirements of the Employee Retirement Income Security Act of 1974. We also sponsor a postretirement health care plan for office employees retired before January 1, 1990. The plan allowed retirees who attained the age of 65 to elect the type of coverage desired. We present the components of net periodic benefit cost (gain) within “Other income (expense), net” on the Condensed Consolidated Statements of Income. Retirement and health care plan expense is based on valuations performed by plan actuaries as of the beginning of each fiscal year. The components of the expense consisted of the following: Three months ended March 31, (table only in thousands) 2020 2019 Pension plan: Interest cost $ 258 $ 326 Expected return on plan assets (350 ) (313 ) Amortization of net actuarial loss 65 65 Net periodic benefit (gain) cost $ (27 ) $ 78 Health care plan: Interest cost $ 1 $ 1 Amortization of loss 2 2 Net periodic benefit cost $ 3 $ 3 We made contributions to our defined benefit plans of approximately $0.1 million during the three-months ended March 31, 2020 and 2019, respectively. For the remainder of 2020, we have elected to defer further contributions to fund the pension plan and the retiree health care plan until January 2021. The unfunded liability of the plans of $8.7 million and $8.9 million as of March 31, 2020 and December 31, 2019, respectively, is included in “Other liabilities” on our Condensed Consolidated Balance Sheets.

Income Tax Disclosure [Abstract]
Income Taxes	1 1 . Income Taxes We file income tax returns in various federal, state and local jurisdictions. Tax years from 2016 forward remain open for examination by Federal authorities. Tax years from 2014 forward remain open for all significant state and foreign authorities. We account for uncertain tax positions pursuant to ASC Topic 740, “Income Taxes.” As of March 31, 2020 and December 31, 2019, the liability for uncertain tax positions totaled approximately $0.2 million and $0.3 million, respectively, which is included in “Other liabilities” on our Condensed Consolidated Balance Sheets. We recognize accrued interest related to uncertain tax positions and penalties, if any, in income tax expense within the Condensed Consolidated Statements of Income. Certain of the Company’s undistributed earnings of our foreign subsidiaries are not permanently reinvested. Since foreign earnings have already been subject to United States income tax in 2017 as a result of the 2017 Tax Cuts and Jobs Act, we intend to repatriate foreign-held cash as needed. We record deferred income tax attributable to foreign withholding taxes that would become payable should we decide to repatriate cash held in our foreign operations. As of March 31, 2020 and December 31, 2019, we have recorded deferred income taxes of approximately $0.8 million and $0.7 million, respectively, on the undistributed earnings of our foreign subsidiaries. A significant portion of the previously undistributed earnings to which the deferred income taxes were attributable were repatriated in 2019. Income tax expense was $0.8 million for both the first quarter of 2020 and 2019. The effective income tax rate for the first quarter of 2020 was 18.6% compared with 31.1% for first quarter of 2019. The effective income tax rate for the first quarter of 2020 is lower than the United States federal statutory rate. Our effective tax rate is affected by certain other permanent differences, including state income taxes, non-deductible incentive stock-based compensation, the Global Intangible Low-Taxed Income inclusion and Foreign-Derived Intangible Income deduction, tax credits, and differences in tax rates among the jurisdictions in which we operate.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies - Legal Matters	1 3 . Commitments and Contingencies – Legal Matters Asbestos cases Our subsidiary, Met-Pro Technologies LLC (“Met-Pro”), beginning in 2002, began to be named in asbestos-related lawsuits filed against a large number of industrial companies including, in particular, those in the pump and fluid handling industries. In management’s opinion, the complaints typically have been vague, general and speculative, alleging that Met-Pro, along with the numerous other defendants, sold unidentified asbestos-containing products and engaged in other related actions which caused injuries (including death) and loss to the plaintiffs. Counsel has advised that more recent cases typically allege more serious claims of mesothelioma. The Company’s insurers have hired attorneys who, together with the Company, are vigorously defending these cases. Many cases have been dismissed after the plaintiff fails to produce evidence of exposure to Met-Pro’s products. In those cases, where evidence has been produced, the Company’s experience has been that the exposure levels are low and the Company’s position has been that its products were not a cause of death, injury or loss. The Company has been dismissed from or settled a large number of these cases. Cumulative settlement payments from 2002 through March 31, 2020 for cases involving asbestos-related claims were $3.1 million, of which, together with all legal fees other than corporate counsel expenses, $2.9 million has been paid by the Company’s insurers. The average cost per settled claim, excluding legal fees, was approximately $35,000. Based upon the most recent information available to the Company regarding such claims, there were a total of 187 cases pending against the Company as of March 31, 2020 (with Illinois, New York, Pennsylvania and West Virginia having the largest number of cases), as compared with 209 cases that were pending as of December 31, 2019. During the three-months ended March 31, 2020, 21 new cases were filed against the Company, and the Company was dismissed from 41 cases and settled two cases. Most of the pending cases have not advanced beyond the early stages of discovery, although a number of cases are on schedules leading to or scheduled for trial. The Company believes that its insurance coverage is adequate for the cases currently pending against the Company and for the foreseeable future, assuming a continuation of the current volume, nature of cases and settlement amounts. However, the Company has no control over the number and nature of cases that are filed against it, nor as to the financial health of its insurers or their position as to coverage. The Company also presently believes that none of the pending cases will have a material adverse impact upon the Company’s results of operations, liquidity or financial condition. Other The Company is also a party to routine contract and employment-related litigation matters, warranty claims and routine audits of state and local tax returns arising in the ordinary course of its business. The final outcome and impact of open matters, and related claims and investigations that may be brought in the future, are subject to many variables, and cannot be predicted. In accordance with ASC 450, “Contingencies”, and related guidance, we record accruals for estimated losses relating to claims and lawsuits when available information indicates that a loss is probable and the amount of the loss, or range of loss, can be reasonably estimated. The Company expenses legal costs as they are incurred. We are not aware of any pending claims or assessments, other than as described above, which may have a material adverse impact on our liquidity, financial position, results of operations, or cash flows.
