How much mortgage can I afford in Canada?

Mortgage affordability in Canada depends on the share of income going to housing, a stress-test rate, and extra monthly costs. Here's a worked example.

Mortgage affordability in Canada is the largest mortgage a lender will approve based on your income, debts, down payment, and a stress-test rate that's higher than the rate you'll actually pay. Start with the share of income going to housing, then check the result against the stress test and your down payment.

What affordability means and how the ratios work

Most Canadians spend 35% to 50% of their income on housing and utilities. That covers mortgage payments, heating, electricity, phone service, and water.

A common benchmark from the Canada Mortgage and Housing Corporation is 30% of gross income for housing costs. It's usually applied to rent, so treat it as a rough starting point rather than a mortgage rule. If you carry student loans or credit card debt, or you're saving for a down payment, aim closer to 25%.

Going higher can make sense if you have no consumer debt, a fully funded emergency fund, and low transportation costs.

The stress test and why it shrinks your limit

Applicants must show they could still afford the mortgage under the higher of two rates:

The rate offered by the lender, plus 2%.
The Minimum Qualifying Rate, currently 5.25%.

A higher qualifying rate means a higher test payment, so the mortgage size you qualify for goes down. The average stress test rate, based on a typical five-year fixed mortgage, has been reported at 6.54%. Your own result depends on the rate you're offered.

Costs beyond the mortgage payment

Property tax and household insurance add to your monthly cost. Condo buyers pay other fees as well, so those belong in your housing budget.

Your down payment matters too. Most banks ask for at least 10% of the home's cost from your own money. Insured mortgage rules set a minimum of 5% on the first $500,000 and 10% on the portion above that.

A worked example of the income gap

Price, income, and the qualifying rate all interact. In Toronto, an income of $232,000 is needed to afford a $1,061,900 home, the average price in the city. The typical Toronto family only qualifies for a maximum mortgage of $574,000. That calculation used a 6.7% qualifying rate.

To run your own numbers, work through these steps:

Take your gross monthly income.
Multiply it by 30% to get a housing budget.
Subtract monthly property tax, household insurance, and any condo fees.
Test what's left as a mortgage payment at a higher qualifying rate, such as your offered rate plus 2%.

Say your gross income is $6,000 a month. At 30%, that gives $1,800. If property tax and insurance come to $400, about $1,400 is left for the mortgage payment. Tested at a higher rate, that payment supports a smaller mortgage than it would at your actual rate. With consumer debt, use 25% and the figure drops further.
