How Mortgages Work in Canada

A mortgage is a loan secured against the property you’re buying. The lender registers a legal claim (lien) on the home, and you make regular payments of principal and interest until the loan is paid off or you sell the property. In Canada, mortgages have several features that differ from other countries.

Mortgage Terms vs. Amortization

One of the most commonly misunderstood concepts in Canadian mortgages is the difference between term and amortization:

At the end of each term, you renew your mortgage — often at a different interest rate. This means Canadian homeowners renegotiate their mortgage multiple times over the life of the loan, unlike the US where 30-year fixed rates lock in for the full amortization.

The Stress Test (B-20 Guidelines)

Since 2018, all Canadian mortgage applicants must pass the federal stress test. You must qualify at the higher of:

• Your contracted mortgage rate plus 2%, or
• The Bank of Canada’s qualifying rate (floor of 5.25%)

This means even if you’re offered a 4.5% rate, you must prove you can afford payments at 6.5%. The stress test limits how much Canadians can borrow and is designed to protect against future rate increases.

Down Payment Rules

Canadian down payment requirements are based on the purchase price:

If your down payment is less than 20%, you must purchase mortgage default insurance from CMHC, Sagen, or Canada Guaranty. This premium (ranging from 2.8% to 4% of the mortgage amount) protects the lender if you default.

Fixed vs. Variable Rates

Historically, variable rates have saved borrowers money over time, but fixed rates offer peace of mind — especially during periods of rising rates.

Semi-Annual Compounding

Canadian fixed-rate mortgages use semi-annual compounding, which is unique compared to the monthly compounding used in the US. This means interest is calculated and compounded twice per year rather than twelve times, resulting in slightly lower effective rates. Variable-rate mortgages in Canada compound monthly.

Key Canadian Mortgage Programs

• First-Time Home Buyer Incentive — Shared equity program through CMHC
• First-Time Home Buyers’ Tax Credit — $1,500 non-refundable federal tax credit
• GST/HST New Housing Rebate — Partial rebate of sales tax on newly built homes

Mortgage Costs Beyond the Monthly Payment

The monthly mortgage payment is just one part of the cost of homeownership:

Understanding these costs is essential for determining true affordability — qualifying for a mortgage doesn’t necessarily mean you can comfortably afford the home.
