The Canada Revenue Agency is changing how it handles some advance income tax ruling requests, giving priority to proposed investments of $1 billion or more in Canada.
The federal agency announced the measure on September 14, 2026, ahead of the Canada Investment Summit. The change is intended to provide major investors with earlier tax certainty about how Canadian income tax law would apply to a proposed transaction.

What the Canada Revenue Agency announced
Under the updated approach, the Canada Revenue Agency will prioritize advance income tax ruling requests connected to investments of at least $1 billion.
An advance income tax ruling is a binding decision from the agency on how tax rules will apply to a proposed transaction. Businesses can seek a ruling before committing capital, helping them assess potential tax treatment before a project moves forward.
The measure applies to qualifying requests related to major investments. It does not create a new tax rate, a new tax credit or an automatic approval process for projects.
Why tax rulings matter for major projects
Large investments often involve complex corporate structures, financing arrangements, acquisitions, reorganizations and cross-border transactions. The tax consequences can affect whether a project proceeds, how it is financed and where related business activity is located.
A ruling can reduce uncertainty by giving an investor the Canada Revenue Agency’s view before a transaction is completed. That does not remove every commercial or regulatory risk, but it can provide more predictability during the planning stage.
For a proposed project worth $1 billion or more, even a small difference in expected tax treatment can represent a substantial financial amount. Faster access to a ruling may therefore help companies make investment decisions sooner.
Existing service standard remains for other requests
The Canada Revenue Agency said requests that do not qualify for priority treatment will continue to be handled under the established 90-business-day service standard, or another service target agreed upon with the applicant.
The agency’s latest published results cited in the announcement show that 91 per cent of advance income tax rulings were issued within the 90-business-day standard, or within a mutually agreed target date, during the fiscal year from April 1, 2024, to March 31, 2025.
The priority process therefore adds a faster track for certain large investments without replacing the existing service approach for other applicants.
How the change fits into broader investment policy
The Canada Revenue Agency described the update as an expansion of measures announced in the 2026 Spring Economic Update. Those measures included priority consideration for large-scale projects considered important to Canada’s economic priorities, including productivity-enhancing investments and clean-economy initiatives.
The new $1-billion threshold creates a clearer benchmark for one category of priority requests. It also signals that tax administration is being used as part of the federal government’s effort to improve certainty for major capital projects.
That approach may be relevant to companies considering energy, infrastructure, manufacturing, technology and other capital-intensive investments. The tax ruling process, however, remains separate from environmental approvals, provincial permits, competition reviews, financing decisions and other requirements.
What businesses should know
The priority applies to advance income tax ruling requests linked to investments of $1 billion or more.
A ruling provides the agency’s binding tax position on a proposed transaction, based on the facts and documentation submitted.
Priority treatment does not guarantee that a project will receive a favourable tax result.
Projects must still meet other federal, provincial and municipal requirements.
Requests outside the priority category remain subject to the regular service standard or an agreed target date.
What happens next
Companies planning to seek an advance income tax ruling will need to provide the agency with detailed information about the proposed transaction and its expected tax treatment.
The practical effect of the announcement will depend on how many requests qualify, how the Canada Revenue Agency applies the priority criteria and whether faster rulings lead to investment decisions that might otherwise have been delayed.
For individuals, the measure does not change personal income tax filing rules, benefit payment dates or access to the agency’s online services. It is directed at large commercial investment proposals and the tax treatment of complex transactions.
