How the mortgage stress test works in Alberta

Short answer: If you are getting a new mortgage in Calgary, Edmonton, Red Deer or elsewhere in Alberta, federally regulated lenders generally do not qualify you at the rate you will pay. They use a stress test, which the Office of the Superintendent of Financial Institutions (OSFI) calls the minimum qualifying rate. For most new mortgages, that rate is the higher of your contract rate plus 2%, or 5.25%. You still pay the contract rate. The higher qualifying rate is a buffer, so the payment you are tested on is one you could still meet if rates or household costs rise (OSFI, Minimum qualifying rate for uninsured mortgages).

What the stress test is

The stress test is a qualification check, not a second interest rate on your mortgage. Lenders look at whether you can afford the payment at the qualifying rate, together with your other housing costs and debts. If you are approved, your actual payment is based on the contract rate you agree to with the lender.

OSFI describes two parts of the minimum qualifying rate for uninsured mortgages:

• The buffer, currently 2 percentage points above the contract rate, as a safety margin for a change in your finances.
• The floor, currently 5.25%, which is meant to account for risks in the broader economy.

OSFI reviews both the floor and the buffer at least once a year, so the figures can change. This article reflects the rule as published on November 10, 2026.

How the qualifying rate is calculated

Lenders take the higher of:

• your contract rate plus 2%, or
• 5.25%.

If the contract rate is below 3.25%, the 5.25% floor is the higher number. If the contract rate is 3.25% or more, the qualifying rate is the contract rate plus 2%. In either case, the rate used to test you is not the rate you pay.

For context on today’s posted figures, see current mortgage rates in Alberta. Posted rates change, and a posted rate is not a quote or a promise of the rate you may be offered.

Who has to pass it

According to the Financial Consumer Agency of Canada (FCAC), you need to pass a stress test to qualify for a mortgage loan at a bank, including when you do not need mortgage loan insurance (FCAC, Mortgage Qualifier Tool). Banks must use the higher of 5.25% or the interest rate you negotiate plus 2%.

OSFI’s guideline covers uninsured mortgages at federally regulated lenders, and it expects those lenders to apply the minimum qualifying rate to most newly underwritten residential mortgages. The FCAC says banks must use the same qualifying rate — the higher of 5.25% or the negotiated rate plus 2% — for insured and uninsured mortgages (FCAC, Preparing to get a mortgage).

Credit unions and other lenders that are not federally regulated are not required to use this federal stress test (FCAC). Some still apply a similar check under their own policies, so do not assume a provincially regulated lender will skip a qualifying-rate test.

When it applies, and when it may not

The stress test generally applies to a new purchase mortgage. The FCAC also notes that if you already have a mortgage, you will need to pass the stress test if you refinance your home or take out a home equity line of credit (FCAC). See refinancing in Alberta and how a HELOC works.

A common exception is a straight switch at renewal. OSFI does not expect federally regulated lenders to apply the minimum qualifying rate when a borrower switches an uninsured mortgage from one federally regulated lender to another, with no increase to the amortization period or the loan amount. Insured mortgages that switch at renewal are generally not re-qualified under the minimum qualifying rate either, provided the switch stays within the rules. If you borrow more, extend the amortization, or otherwise change the loan in a way that is not a straight switch, you should expect to be qualified again. More on renewing a mortgage in Alberta.

What it means in Calgary, Edmonton and across Alberta

• The rule is the same across the province. Whether you are buying a condo in Calgary, a starter home in Edmonton or Red Deer, or a place in a smaller Alberta community, the federal qualifying rate does not change by city.
• Your budget is more than the rate on a rate sheet. Lenders also weigh income, existing debts, property tax, heating and, for condos, a portion of the condo fees, against the payment at the qualifying rate. That is why the mortgage you may qualify for can be smaller than the contract-rate payment would suggest. First-time buyers can start with the first-time home buyer guide and how the minimum down payment works in Alberta. If you are looking at a Calgary condo, see the Calgary condo mortgage guide.
• A pre-approval builds the test in. A mortgage pre-approval is a practical way to see a realistic range before you shop, including the stress test. Many pre-approvals include a rate hold for a set period; holds vary by lender and are not a final approval. More detail is in how a pre-approval rate hold works in Alberta.

How to prepare

1. Gather recent income documents, a list of debts and a clear down-payment source. Lenders will want to see where the money comes from.
2. Keep your job, credit and debts steady while you shop and wait for closing. A new loan or a large new balance can change the picture.
3. Use posted rates for context, then talk through a qualifying scenario rather than treating a posted figure as the payment you will be tested on.
4. If you are renewing, ask whether your plans are a straight switch or a refinance, because the stress test treatment can differ.
