Fixed vs Variable Mortgages in Canada: How to Choose

Most borrowers ask one question: “What’s the lowest rate?” A better question is: “Which mortgage will still work if my plan changes?” Fixed and variable mortgages behave differently — especially when you break early, renew, or need flexibility.

Fixed Rate: What It Is

A fixed-rate mortgage locks your interest rate for the term (often 1–5 years). Your payment is predictable, which can help with budgeting. The trade-off is typically less flexibility and potentially higher break penalties with some lenders.

Variable Rate: What It Is

A variable-rate mortgage moves with your lender’s prime rate. Payments may stay the same while the interest portion changes (or payments may change — it depends on the product). Variable can offer savings when rates fall, and often has lower break penalties — but it can be more stressful if rates rise.

The Big Factor People Miss: Penalties

Many Canadians break their mortgage early (selling, refinancing, separation/divorce, renovations). In those situations, the penalty can matter more than the rate. Fixed mortgages at some lenders can have sizable penalties, while many variable mortgages are simpler to exit.

Choose the mortgage that fits your timeline and flexibility needs — not just today’s rate.

A Simple Decision Framework

• If you’ll likely move or refinance within 1–3 years, variable (or a flexible fixed) often deserves a hard look.
• If you value payment certainty and can commit to the term, fixed can be a good fit.
• If stress matters more than savings, fixed may help you sleep — but compare penalty risk.
• If you’re self-employed or your income is changing, flexibility can be worth more than a slightly lower rate.

Fixed vs Variable in a Downward Rate Environment

When rates are expected to fall, variable may benefit sooner. Fixed rates often price in expectations ahead of time. The right choice depends on your risk tolerance, timeline, and how likely you are to break early.

What I Recommend Doing

1. Confirm your likely timeline (how long you’ll keep this mortgage).
2. Compare penalties and restrictions, not just the rate.
3. Choose the term and product that matches your plan — then negotiate pricing.
