Benchmark Rate
A published reference rate — such as the Bank of Canada's policy rate or prime rate — that other interest rates are quoted against..
A benchmark rate is a published reference rate that other interest rates are quoted against. Rather than pricing every loan from scratch, Canadian lenders and borrowers anchor pricing to a shared, publicly observable rate and then add or subtract a spread. Common examples include the Bank of Canada's policy interest rate, the prime rate banks post, CORRA in short-term funding markets, and Government of Canada bond yields used to price fixed mortgages.
Common benchmark rates in Canada
Each benchmark anchors a different part of the mortgage market:
- Policy interest rate — set by the Bank of Canada; changes flow through to the prime rate and therefore to variable-rate mortgages and home equity lines of credit.
- Prime rate — the base lenders use to quote variable products, described as "prime plus" or "prime minus".
- CORRA — the Canadian Overnight Repo Rate Average, a market-based reference for short-term funding.
- Government of Canada bond yields — medium-term yields, especially the five-year, shape fixed mortgage pricing.
A benchmark is not the rate a borrower pays. It is the starting point, and the lender's spread reflects funding costs, competition, the property, and the borrower's profile.
Why a benchmark rate matters to a borrower
Benchmarks explain why mortgage rates move when nothing about your own finances has changed. When the policy interest rate shifts, prime rate usually follows, which moves payments on adjustable-rate variable mortgages and lines of credit. When bond yields rise or fall, fixed mortgage rates tend to follow. Benchmarks also matter at qualification: the federal mortgage stress test requires borrowers to qualify at a rate above their contract rate — either the contract rate plus a buffer or a posted floor rate, whichever is higher.

Benchmark rate vs a lender's posted rate
These are related but not identical. A posted rate is a lender's own published list rate; it can act as a benchmark for discounts and contractual wording, but it is set by that lender. A market benchmark such as the policy rate or a bond yield is set independently of any single lender. Understanding how mortgage rates work in Canada helps borrowers see which benchmark drives the product they are choosing.
Frequently asked questions
What is Canada's benchmark interest rate?
There is no single one. The Bank of Canada's policy interest rate is the main benchmark for short-term borrowing and flows through to prime rate. Government of Canada bond yields, especially the five-year, are the benchmark behind fixed mortgage pricing, while CORRA anchors short-term funding markets. Different products reference different benchmarks.
Is the Bank of Canada policy rate the same as prime rate?
No. The policy interest rate is set by the Bank of Canada. Prime rate is set by each commercial lender and typically moves in step with changes to the policy rate, but it is a separate published number. Variable mortgage rates are usually quoted as prime plus or minus a spread.
Does the benchmark rate affect mortgage stress test qualification?
Yes. The federal stress test requires borrowers to qualify at a rate above their mortgage contract rate — generally the contract rate plus a buffer or a posted floor rate, whichever is higher. That qualifying rate is a type of benchmark, so benchmark movements can change how much a borrower may qualify for.
