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,” “CECO,” “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 financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) 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 June 30, 2022 and the results of operations, cash flows and shareholders’ equity for the three-month and six-month periods ended June 30, 2022 and 2021. The results of operations for the three-month and six-month periods ended June 30, 2022 are not necessarily indicative of the results to be expected for the full year. The balance sheet as of December 31, 2021 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, 2021 as filed with the SEC on March 14, 2022 (the “Form 10-K”). The preparation of financial statements in conformity with 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 Form 10-K. Unless otherwise indicated, all balances within tables are in thousands, except per share amounts. COVID-19 A novel strain of coronavirus (“COVID-19”) surfaced in late 2019 and has spread around the world, including to the United States. In March 2020, the World Health Organization characterized COVID-19 as a pandemic. As of June 30, 2022, the virus, including new emerging variants, continues to spread and has had a significant impact on worldwide economic activity, on macroeconomic conditions and the end markets of our business. The outbreak and a continued spread of COVID-19 has resulted in a substantial curtailment of business activities worldwide and has caused weakened economic conditions, both in the United States and abroad. Although vaccines are available in various countries where we operate, it is possible the COVID-19 pandemic may continue to have a negative impact on the Company's ongoing operations and the end markets in which it serves. However, the full impact of the COVID-19 pandemic continues to evolve as of the date of this filing, and as such, it is uncertain as to the full magnitude or lasting impact 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 pandemic on its financial condition, liquidity, operations, suppliers, industry, and workforce.

New Financial Accounting Pronouncements	2. New Financial Accounting Pronouncements Accounting Standards adopted in Fiscal 2022 None. Accounting Standards to be Adopted In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which addresses how an acquirer should recognize and measure revenue contracts acquired in a business combination. This ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position and/or results of operations.

Amortization over the next five years for finite life intangibles is expected to be $ 3.9 million for the remainder of 2022, $ 6.5 million in 2023, $ 5.6 million in 2024, $ 4.5 million in 2025, and $ 3.2 million in 2026 . 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 the 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. As of June 30, 2022, 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. The Company did not identify any triggering events during the three-month period ended June 30, 2022 that would require an interim impairment assessment of goodwill or intangible assets. 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 analysis accordingly.

Income Taxes	11. Income Taxes We file income tax returns in various federal, state and local jurisdictions. Tax years from 2018 forward remain open for examination by Federal authorities. Tax years from 2016 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 June 30, 2022 and December 31, 2021, the liability for uncertain tax positions totaled approximately $ 0.1 million, 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 Operations. 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 June 30, 2022 and December 31, 2021, we have recorded deferred income taxes of approximately $ 1.5 million and $ 1.1 million, respectively, on the undistributed earnings of our foreign subsidiaries. Income tax expense was $ 1.9 million for the second quarter of 2022 and $ 3.0 million for the first six months of 2022 compared with income tax expense of $ 0.2 million for the second quarter of 2021 and $ 0.8 million for the first six months of 2021. The effective income tax rate for the second quarter of 2022 was 28.3 % compared with 34.3 % for the second quarter of 2021. The effective income tax rate for the first six months of 2022 was 28.3 % compared with 30.9 % for the first six months of 2021. The effective income tax rate for the three and six months ended June 30, 2022 is higher than the United States federal statutory rate. Our effective rate is affected by certain other permanent differences, including state income taxes, non-deductible incentive stock-based compensation and differences in tax rates among jurisdictions in which we operate.

Investments, All Other Investments [Abstract]
Financial Instruments	12. Financial Instruments Our financial instruments consist primarily of investments in cash and cash equivalents, receivables and certain other assets, foreign debt and accounts payable, which approximate fair value at June 30, 2022 and December 31, 2021, due to their short-term nature or variable, market-driven interest rates. The fair value of the debt issued under the Credit Facility and joint venture term loan was $ 97.6 million and $ 65.5 million at June 30, 2022 and December 31, 2021, respectively. The fair value was determined considering market conditions, our credit worthiness and the current terms of our debt, which is considered Level 2 on the fair value hierarchy. At June 30, 2022 and December 31, 2021, the Company had cash and cash equivalents of $ 34.4 million and $ 29.9 million, respectively, of which $ 26.5 million and $ 22.6 million, respectively, was held outside of the United States, principally in the Netherlands, United Kingdom, China, and Canada.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies - Legal Matters	13. 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 June 30, 2022 for cases involving asbestos-related claims were $ 5.7 million, of which, together with all legal fees other than corporate counsel expenses, $ 5.6 million has been paid by the Company’s insurers. The average cost per settled claim, excluding legal fees, was approximately $ 44,000 . Based upon the most recent information available to the Company regarding such claims, there were a total of 256 cases pending against the Company as of June 30, 2022 (with Illinois, New York, Pennsylvania and West Virginia having the largest number of cases), as compared with 223 cases that were pending as of December 31, 2021. During the six-months ended June 30, 2022, 79 new cases were filed against the Company, and the Company was dismissed from 36 cases and settled 10 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.
