| Accounting Policies [Abstract] | |
| Basis of preparation | These unaudited interim condensed consolidated financial statements for the period ended March 31, 2026 (Q1 2026 Interim Financial Statements) have been prepared in accordance with generally accepted accounting principles in the United States (GAAP) for interim financial reporting, and the instructions to Form 10-Q and Article 10 of Regulation S-X. Certain information or footnote disclosures, normally included in annual financial statements prepared in accordance with GAAP, have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission for interim financial reporting. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The Q1 2026 Interim Financial Statements, in the opinion of management, reflect all normal and recurring adjustments necessary to present fairly our financial position, operating results and cash flows for the periods presented. Results for interim periods are not necessarily an indication of results to be expected for the year. The three months ended March 31, 2026 are referred to herein as Q1 2026. The Q1 2026 Interim Financial Statements should be read in conjunction with our 2025 annual consolidated financial statements and related notes (2025 AFS) which are included in our Annual Report on Form 10-K for the year ended December 31, 2025. The Q1 2026 Interim Financial Statements are presented in United States (U.S.) dollars, which is also Celestica's functional currency. Unless otherwise noted, all financial information is presented in millions of U.S. dollars (except percentages and per share/per unit amounts). |
| Basis of consolidation | These consolidated financial statements include our subsidiaries, all of which are wholly owned. Any subsidiaries that are formed or acquired during the year are consolidated from their respective dates of formation or acquisition. Inter-company transactions and balances are eliminated on consolidation. |
| Use of estimates and judgments | The preparation of financial statements requires management to make judgments, estimates and assumptions that affect the application of accounting policies, the reported amounts of assets, liabilities, revenue and expenses, and related disclosures with respect to contingent assets and liabilities. We base our judgments, estimates and assumptions on current facts, historical experience and various other factors that we believe are reasonable under the circumstances. The economic environment also impacts certain estimates and discount rates necessary to prepare our consolidated financial statements, including significant estimates and discount rates applicable to the determination of the fair values used in the impairment testing of our non-financial assets. Our assessment of these factors forms the basis for our judgments on the carrying values of our assets and liabilities, and the accrual of our costs and expenses. Actual results could differ materially from our estimates and assumptions. We review our estimates and underlying assumptions on an ongoing basis and make revisions as determined necessary by management. Revisions are recognized in the period in which the estimates are revised and may also impact future periods. Our review of the estimates, judgments and assumptions used in the preparation of the Q1 2026 Interim Financial Statements included those relating to, among others: our determination of the timing of revenue recognition, the determination of whether indicators of impairment existed for our assets and reporting units, our measurement of deferred tax assets and liabilities, our estimated inventory write-downs and expected credit losses, and customer creditworthiness. Any revisions to estimates, judgments or assumptions may result in, among other things, write-downs, accelerated depreciation or amortization, or impairments of our assets or our reporting units, any of which could have a material impact on our financial performance and financial condition. Due to global economic conditions, including the impact of ongoing trade conflicts, tariffs, and geopolitical conflicts, there has been and we expect there will continue to be uncertainty in the global economy. Management has made estimates and assumptions based on information available as of the date of issuance of the Q1 2026 Interim Financial Statements taking into consideration certain possible impacts due to the foregoing factors. These estimates may change, as new events occur, and additional information is obtained.

| Recently issued accounting pronouncements not yet adopted | Recently issued accounting pronouncements not yet adopted: In November 2024, the FASB issued ASU 2024-03 Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires public business entities to provide more detailed disclosures of certain costs and expenses in the notes to the financial statements. Specifically, the guidance mandates a tabular disaggregation of relevant expense captions into categories including inventory purchases, employee compensation, depreciation, and intangible asset amortization. The accounting standard update is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. In November 2025, the FASB issued ASU 2025-09 Derivatives and Hedging (Topic 815): Hedge Accounting Improvements, which expands the hedged risks permitted to be aggregated in a group of individual forecasted transactions in a cash flow hedge, provides a model to facilitate the application of cash flow hedge accounting to forecasted interest payments on variable-rate debt instruments and expands hedge accounting for forecasted purchases and sales of non-financial assets. ASU 2025-09 is effective for annual reporting periods beginning after December 15, 2026, with early adoption permitted. In December 2025, the FASB issued ASU 2025-12 Codification Improvements, which provides narrow-scope amendments to clarify, correct errors, and improve the consistency of various topics within the Accounting Standards Codification. The update addresses several technical issues, including refining diluted earnings per share calculations during loss periods, clarifying lease receivable disclosures, and removing obsolete Master Glossary terms to enhance the overall usability of the guidance. ASU 2025-12 is effective for annual periods beginning after December 15, 2026, with early adoption permitted. In December 2025, the FASB issued ASU 2025-11 Interim Reporting (Topic 270): Narrow-Scope Improvements, which clarifies interim disclosure requirements. ASU 2025-11 is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. We are currently evaluating the impact that the updated standards will have on our consolidated financial statements and related disclosures. We believe that other recently issued accounting standards will either not have a material impact on the consolidated financial statements or will not apply to our operations. |
