Variable Mortgage Rates in Canada

What is a variable mortgage rate?

A variable mortgage rate is a rate that can change during your mortgage term, typically moving with the lender's prime rate. In Canada, variable rates are usually quoted as prime minus a discount, and that discount stays fixed for the term.

• The rate you pay can fluctuate, so your payment may change or the split between interest and principal may shift.
• Variable-rate mortgages come in two main types: fixed-payment (VRM) and variable-payment (ARM).

How variable rates are set in Canada

Variable mortgage rates in Canada are tied to the Bank of Canada's policy interest rate, which influences the prime rate set by banks and other lenders. When the Bank of Canada raises or lowers its overnight rate, the prime rate typically moves in the same direction, and variable mortgage rates follow.

• As of August 2026, the Bank of Canada held its overnight rate at 2.25%, and the prime rate at major banks was 4.45%.
• The prime rate can vary slightly between lenders, but it generally moves in step with the Bank of Canada's rate.

Variable vs fixed: key differences

The main difference is that a fixed-rate mortgage locks your interest rate and payment for the term, while a variable rate can change. With a variable rate, your payment may stay the same (if it's a fixed-payment VRM) or change with the rate (if it's an ARM).

Scenarios: when variable rates can cost more or less

Whether a variable rate costs more or less over the long run depends on how rates move during your term. If the Bank of Canada's key rate stays flat or declines, a variable rate may end up cheaper than a fixed rate. If the key rate rises sharply, the opposite can be true.

• With a fixed-payment VRM, a rate increase doesn't change your payment immediately, but a larger share goes to interest, so you build equity more slowly.
• If rates keep climbing, you could hit your trigger rate. At that point, your payment covers only the interest and no principal (with most lenders).
• In extreme cases, you could face negative amortization, where unpaid interest is added to your mortgage principal, meaning you owe more over time.

Pros and cons of variable-rate mortgages

Variable rates can be attractive because they often start lower than fixed rates, and you can benefit if rates fall. They also typically have lower prepayment penalties than fixed-rate mortgages.

• Pros: lower initial rate, potential savings if rates drop, lower prepayment penalties.
• Cons: payment uncertainty (with ARMs), the risk of trigger rates and negative amortization with VRMs, and the need for a higher risk tolerance.

How to decide if a variable rate is right for you

Choosing between a variable and fixed rate comes down to your financial situation and comfort with risk. If you have a stable budget and can absorb payment changes, a variable rate might suit you. If you need predictable payments or expect rates to rise, a fixed rate could be safer.

• Consider your cash flow: can you handle a higher payment if you choose an ARM?
• Think about your trigger rate: if you have a fixed-payment VRM, know what rate would cause your payment to cover only interest.
• Most lenders allow you to convert to a fixed rate during your term without penalty, which gives you an option if rates start climbing.

Side-by-side category and decision-criteria matrix

The table above compares the categories of variable-rate (VRM), adjustable-rate (ARM), and fixed-rate mortgages. Key decision criteria include payment stability, flexibility, and prepayment penalties. A variable rate offers lower penalties and potential savings, but fixed rates offer certainty. Your choice depends on your risk tolerance and market outlook.

• Payment stability: fixed > VRM > ARM.
• Potential for lower cost: variable (VRM or ARM) can be lower if rates stay flat or drop.
• Prepayment penalty: variable usually lower (three months' interest) than fixed.
