What the stress test is trying to measure
Mortgage qualification can include an affordability test at a rate above the actual contract rate. The purpose is to test whether the borrower could still carry the mortgage under a more demanding payment assumption.
That does not mean one generic percentage is the correct qualifying rate for every borrower or every transaction. Current rules, lender requirements, insured or uninsured status, transaction type, debt obligations, property costs, income treatment, and other underwriting assumptions can matter.
Why FairRate does not publish a live-looking generic qualifying rate here
A common online shortcut is to take a representative mortgage rate, add a fixed spread, compare it with a floor, and present the result as a current qualifying rate. That can create false precision because the starting contract rate and the rule that applies to a specific transaction may differ.
FairRate therefore does not use configured fallback mortgage rates to manufacture a current qualifying-rate figure on this page. Verify the current requirement and assumptions for your exact transaction before acting.
Transactions should not be treated as identical
- Same-lender renewal: Ask what documentation or qualification review applies to the renewal being offered.
- Lender switch: Verify the current qualification rule, documentation, timing, fees, transfer requirements, and product restrictions for the exact switch.
- Refinance or increased borrowing: Additional borrowing or other material changes can alter qualification and documentation requirements.
- Amortization change: Extending or otherwise changing amortization can affect payment and qualification assumptions.
- Other material changes: Borrower, property, product, or security changes may matter and should be verified directly.
Questions to ask before relying on a qualification estimate
- Which current qualifying rule applies to this exact transaction?
- What contract rate or benchmark input is being used?
- What income is included and how is variable or self-employed income treated?
- Which debts and housing costs are included?
- What amortization and payment frequency are assumed?
- Are there lender-specific overlays or documentation requirements?
- Does changing lenders, balance, amortization, or borrowers change the analysis?
Province guides are context, not province-priced qualification
Mortgage qualification is not created by a FairRate province-specific pricing model. Province pages can help organize local context, terminology, and review questions, but they should not be read as proof that a borrower in one province has a different guaranteed benchmark or qualifying rate solely because of location.

FairRate limitation
FairRate is not a lender, mortgage broker, mortgage agent, underwriter, law firm, or financial advisor. It does not determine whether a borrower qualifies and does not issue mortgage approvals. For a high-stakes qualification question, verify the current requirements with the relevant lender and, where appropriate, a licensed mortgage professional.

Frequently asked questions
What is the Canadian mortgage stress test?
The mortgage stress test is a qualification concept that can require a borrower to demonstrate affordability at a rate above the contract rate. The exact qualifying rule and whether it applies can depend on the transaction, lender, mortgage type, and current requirements.
What qualifying rate should I use?
Do not rely on a generic website estimate as your actual qualifying rate. Ask the relevant lender or a licensed mortgage professional which current qualifying rule applies to your exact transaction and request the assumptions used.
Does the stress test affect renewals?
Renewals should not be treated as one uniform category. A same-lender renewal, a lender switch, a refinance, increased borrowing, an amortization change, and other material changes can involve different requirements. Verify the current rule for the exact transaction.
Can FairRate tell me whether I qualify?
No. FairRate does not provide mortgage approval, underwriting, or qualification decisions. It provides educational comparison context only.
