Canada Transfer Pricing Updates and Changes 2026

Canada has delivered its biggest transfer pricing change in a generation. With Bill C-15, the rules in section 247 of the Income Tax Act have been rewritten, the documentation regime has been tightened, and a Supreme Court decision has reshaped how downward adjustments are litigated. On top of that, the first global minimum tax filings fall due in 2026. For any group with Canadian operations, the compliance burden and the audit risk have both stepped up. Here is what changed, who is affected, and what to do about it.

A rewritten section 247: from form to substance

For years, Canada's transfer pricing rule worked in two parts: a pricing adjustment, and a separate, hard-to-meet test for recharacterising a transaction. Following the government's loss in the Cameco case and a 2023 consultation, that structure is gone. Bill C-15, which received Royal Assent on 26 March 2026, replaces it with a single operative adjustment rule that applies to taxation years beginning after 4 November 2025. For a company with a December year-end, the first affected year is 2026.

The new rule is delineation-first. Before any pricing question, the tax authority works out what the transaction actually is by reference to its economically relevant characteristics: the contractual terms to the extent they match actual conduct, the functions performed, assets used and risks assumed, the characteristics of the property or services, and the economic circumstances and business strategies. It then compares the actual conditions of the transaction with arm's length conditions. Where they differ, the Canada Revenue Agency adjusts to arm's length and, where appropriate, can treat the transaction as one that would not have occurred or replace it with the transaction that would have. The analysis weighs the options realistically available to each party, including the option of not transacting at all.

A new interpretation rule ties section 247 to the OECD Transfer Pricing Guidelines, anchored to the version approved on 7 January 2022. The practical effect is a shift from legal form to economic substance and actual conduct, and that is a real break from the case law many Canadian structures were built on.

What to do: Re-run your transfer pricing analysis for material related-party dealings under the new delineation and arm's length conditions test, and make sure your intercompany agreements reflect what the parties actually do. Positions that relied on the old, form-driven, high-recharacterisation-threshold approach are the most exposed.

Broader Transfer Pricing documentation and a 30-day clock

The documentation rules changed alongside the adjustment rule. Contemporaneous documentation must now follow the same delineation logic: it has to describe the property or services and the contractual terms, the participants and their relationships, the functional analysis based on actual conduct, the method selection under the OECD Guidelines, and the economic circumstances and strategies. It also reaches wider, to transactions with other group members, how the taxpayer's functions contribute to the group's overall value, and industry practice.

Two changes bite hardest. The deadline to hand documentation to the Canada Revenue Agency on request drops from three months to 30 days. And the penalty threshold rises from a $5 million net adjustment to $10 million, with the alternative 10 percent of gross revenue test retained; the penalty itself remains 10 percent of the relevant adjustment. There is no new stand-alone master file requirement, and a simplified documentation option is expected to arrive by regulation.

What to do: Prepare fuller, delineation-aligned documentation by your filing due date, and build a process that can produce it within 30 days. The old three-month cushion is gone, and thin or template-only files now carry more penalty risk on larger adjustments.

Dow Chemical: two courts for downward adjustments

In Dow Chemical Canada ULC v Canada (2024 SCC 23, decided 28 June 2024), the Supreme Court of Canada ruled, by a four to three majority, on where downward transfer pricing adjustments are contested. Where the Minister uses the discretion in subsection 247(10) to refuse a taxpayer's requested downward adjustment, that decision is reviewed by the Federal Court on judicial review, not by the Tax Court on an appeal of the assessment. The result is that a taxpayer may have to run two separate proceedings, in two different courts, to challenge an upward adjustment and to pursue the matching downward adjustment.

What to do: If you have, or expect, a downward adjustment position in Canada, set your dispute strategy around this split jurisdiction from the outset. Identify the right forum and the applicable deadlines early, and coordinate the two tracks so a procedural gap does not leave relief stranded.

The first global minimum tax filings fall due in 2026

Separately from the transfer pricing changes, Canada's Global Minimum Tax Act now brings a live filing deadline. Qualifying multinational groups, broadly those with consolidated revenue of EUR 750 million or more, face their first GloBE Information Return and Canadian global minimum tax return for fiscal years beginning on or after 31 December 2023. For most groups the first filing is due on 30 June 2026, being 15 months after the year end, with up to 18 months in the first year where conditions are met. Filing runs through the Canada Revenue Agency's digital interface rather than paper forms, and no extension to the 30 June 2026 date is on the table.

This is a minimum tax obligation rather than a transfer pricing rule, but the two are linked: transfer pricing outcomes drive the jurisdictional profits and effective tax rates that the global minimum tax calculation depends on.

What to do: Confirm whether your group is in scope and whether you are ready to file by 30 June 2026, and check that your transfer pricing data lines up with what the global minimum tax return will report.

The common thread

Canada's 2026 message is consistent: transfer pricing will be judged on economic substance and actual conduct, documented in more depth, produced faster, and defended through a more demanding process. The groups most exposed are those whose Canadian positions look settled on paper but were built on the old form-driven rules, or whose documentation cannot be produced, in full, within 30 days. The time to test those positions is before the Canada Revenue Agency does.
