Key Takeaway

Fixed-rate mortgages lock your interest rate for the entire term (typically 1 to 5 years), giving you predictable payments but potentially higher initial rates. Variable-rate mortgages fluctuate with the Bank of Canada policy rate, offering lower starting rates but payment uncertainty. Choose fixed if you prioritize budget stability and expect rates to rise; choose variable if you can tolerate payment changes and believe rates will stay flat or decline during your term.

Why Your Rate Type Matters in Canada

When you secure a mortgage in Canada, one of your most important decisions is whether to lock in a fixed rate or accept a variable rate that moves with the market. This choice affects your monthly payment, your total interest cost over the term, and how vulnerable you are to Bank of Canada rate changes.

Unlike a 30-year fixed mortgage common in the United States, Canadian mortgages separate the term (the period your rate contract lasts, often 1 to 5 years) from the amortization (the full payoff period, typically 25 or 30 years). At the end of each term, you renew or renegotiate, making your rate-type decision a recurring one that shapes your borrowing strategy over decades.

What You Will Learn

This guide walks you through how fixed-rate and variable-rate mortgages work in Canada, the trade-offs of each option, and a practical framework for choosing the rate type that aligns with your budget, risk tolerance, and interest-rate outlook.

Understanding Fixed-Rate Mortgages in Canada

A fixed-rate mortgage guarantees the same interest rate for the entire term, regardless of what the Bank of Canada does with the policy rate or how bond markets move. Your monthly principal-and-interest payment stays constant, making budgeting straightforward.

How Fixed Rates Are Set

Lenders price fixed-rate mortgages based on Government of Canada bond yields (especially the 5-year bond for a 5-year term) plus a margin. When bond yields rise, fixed mortgage rates typically follow. According to the Financial Consumer Agency of Canada, fixed rates reflect the lender’s cost of funding the loan for the full term, which is why they tend to be higher than variable rates when the yield curve is normal.

Advantages of Fixed Rates

  • Payment certainty: Your rate and payment do not change, protecting you from rising rates.
  • Easier budgeting: You know exactly what you will pay each month for the term.
  • Peace of mind: No need to monitor Bank of Canada announcements or worry about payment shocks.

Disadvantages of Fixed Rates

  • Higher starting rate: Fixed rates are often 0.25 to 0.75 percentage points higher than variable rates at the time you sign.
  • Prepayment penalties: Breaking a fixed-rate mortgage early (for example, to refinance or sell before the term ends) typically triggers an interest rate differential (IRD) penalty, which can be substantial.
  • No benefit from falling rates: If the Bank of Canada cuts rates during your term, your payment stays the same.

Understanding Variable-Rate Mortgages in Canada

A variable-rate mortgage (also called an adjustable-rate mortgage) has an interest rate that moves in step with the lender’s prime rate, which in turn follows the Bank of Canada policy rate. When the Bank raises or lowers its overnight rate, your mortgage rate adjusts (usually within days), and your payment changes accordingly.

How Variable Rates Are Set

Variable rates are quoted as prime minus (or plus) a discount. For example, prime minus 0.50 per cent means you pay 0.50 percentage points below the lender’s prime rate. As of July 2026, if prime is 5.95 per cent, your rate would be 5.45 per cent. When the Bank of Canada raises the policy rate, lenders raise prime, and your mortgage rate climbs.

Advantages of Variable Rates

  • Lower starting rate: Variable rates typically start lower than fixed rates, reducing your initial payment and total interest cost if rates stay flat or fall.
  • Lower prepayment penalties: Breaking a variable-rate mortgage usually triggers a penalty of three months’ interest, far less severe than the IRD on a fixed mortgage.
  • Benefit from rate cuts: If the Bank of Canada lowers rates, your payment drops automatically.

Disadvantages of Variable Rates

  • Payment uncertainty: Your payment can rise if the Bank of Canada raises rates, straining your budget.
  • Stress and monitoring: You need to watch rate announcements and plan for potential increases.
  • Risk of higher costs: If rates rise sharply during your term, you may end up paying more total interest than you would have with a fixed rate.

How to Choose Between Fixed and Variable Rates

Your choice depends on three factors: your budget flexibility, your interest-rate outlook, and your risk tolerance.

Step 1: Assess Your Budget and Cash Flow

Ask yourself: can you absorb a payment increase of 10 to 20 per cent without financial hardship? If your budget is tight and a rate hike would force you to cut essential expenses, a fixed rate offers safer footing. If you have room in your cash flow and could handle higher payments, a variable rate gives you the chance to save when rates are stable or falling.

Step 2: Consider the Rate Environment and Your Forecast

Look at the current spread between fixed and variable rates and the direction of Bank of Canada policy. If fixed rates are only marginally higher than variable (say, 0.25 percentage points), locking in may be worthwhile for the certainty. If the spread is wide (0.75 percentage points or more) and you believe the Bank is done raising rates or may cut soon, variable offers better value.

Keep in mind that forecasting rates is difficult. Historically, variable-rate borrowers in Canada have paid less total interest over long periods, but individual outcomes vary by term.

Step 3: Evaluate Your Risk Tolerance and Time Horizon

If the thought of a rising payment keeps you awake at night, choose fixed and accept the higher starting rate as the cost of peace of mind. If you are comfortable with uncertainty and can adjust your spending as rates move, variable may deliver lower costs. Also consider your term length: a shorter term (1 or 2 years) with a variable rate exposes you to less rate-change risk than a 5-year variable commitment.

Common Mistakes to Avoid

  • Choosing variable solely because the rate is lower today: The starting rate is only part of the equation. Consider what could happen over the full term.
  • Ignoring the prepayment penalty difference: If there is any chance you will sell, refinance, or pay off the mortgage early, the lower penalty on a variable-rate mortgage can save thousands.
  • Not stress-testing your budget: Under the OSFI B-20 guideline, lenders qualify you at a higher rate, but you should also run your own stress test to see if you could handle a 1 to 2 percentage point increase in your variable rate.

Frequently Asked Questions

Can I switch from variable to fixed during my term?

Yes, most lenders allow you to convert a variable-rate mortgage to a fixed rate at any time during the term, though the new fixed rate will be the lender’s current posted rate (often higher than the discounted rate you could negotiate when shopping). There is typically no penalty to convert, but confirm the terms with your lender.

Do I requalify under the stress test when I renew?

When you renew with your existing lender at the end of your term, you do not need to requalify under the mortgage stress test. If you switch to a new lender, the new lender will stress-test you at the qualifying rate set by OSFI. This difference can influence whether you lock in a longer term now or plan to switch lenders at renewal.

Conclusion

Choosing between a fixed-rate and variable-rate mortgage in Canada comes down to balancing certainty against potential savings. Fixed rates protect you from rising payments and simplify budgeting, while variable rates offer lower starting costs and flexibility if the Bank of Canada cuts rates. Assess your cash-flow cushion, your view on where rates are headed, and how much payment uncertainty you can tolerate, then select the rate type that aligns with your financial situation and peace of mind.

Before you commit, compare offers from multiple lenders (including both fixed and variable options), review the prepayment terms and penalties, and confirm the fine print with a licensed mortgage broker. Rates and products vary by lender and province, so verify current terms for your specific circumstances.
