Fixed vs Variable Mortgage Canada

The most important mortgage decision Canadian borrowers face — explained clearly for 2025.

The Core Difference

A fixed-rate mortgage locks your interest rate for the entire term — typically 1, 2, 3, or 5 years. Your payment amount never changes during that term, regardless of what the Bank of Canada does. A variable-rate mortgage fluctuates with the prime rate, which moves when the Bank of Canada changes its overnight target rate.

Both have served Canadian borrowers well at different times. The "right" choice depends on the current rate environment, your financial flexibility, and your psychological comfort with uncertainty.

How Variable Rates Work in Canada

Variable rates in Canada are typically expressed as "prime minus" a discount. For example, if prime is 5.45% and your variable rate is prime minus 0.75%, your effective rate is 4.70%. When the Bank of Canada cuts the overnight rate, your lender usually drops prime within days, and your mortgage rate drops automatically.

There are two types of variable mortgages in Canada:

• Adjustable-rate mortgage (ARM): Your actual payment changes when prime moves. Your principal paydown stays consistent but your payment dollar amount adjusts.
• Variable-rate mortgage (VRM): Your payment stays fixed but the split between principal and interest changes. If prime rises sharply, you may hit a "trigger rate" where your payment no longer covers interest.

The trigger rate became a serious issue for thousands of Canadian borrowers during the 2022–2023 rate hike cycle. Many VRM holders saw their payments cover only interest — or worse, negative amortization occurred where the principal actually grew.

Fixed vs Variable: Head-to-Head Comparison

Factor	Fixed Rate	Variable Rate
Payment certainty	Fully predictable	Can change with prime
Rate level (2025)	4.49%–5.49%	4.45%–5.10%
Break penalty	IRD (can be very large)	3 months interest (smaller)
Historical performance	More expensive long-term	Cheaper ~70% of the time
Best for	Budget-constrained buyers	Rate-savvy, flexible buyers
Risk level	Low	Medium to high

The Penalty Asymmetry Is Huge

One of the most overlooked differences between fixed and variable mortgages in Canada is the break penalty. If you need to exit your mortgage early — because you sell, divorce, refinance, or face financial hardship — the costs are very different.

Variable-rate penalties are typically 3 months of interest. On a $500,000 mortgage at 4.70%, that is roughly $5,875. Breaking a fixed-rate mortgage involves the Interest Rate Differential (IRD), a calculation that can easily run $15,000–$30,000 on the same mortgage. Big banks use their own posted rates in the IRD calculation, which inflates penalties dramatically. Monoline lenders use bond rates, which results in fairer (lower) penalties.

What Happened During the 2022–2024 Rate Cycle

The Bank of Canada raised its overnight rate from 0.25% to 5.00% between March 2022 and July 2023 — one of the fastest rate hike cycles in Canadian history. Variable-rate borrowers saw their effective rates jump by nearly 5 percentage points. Many were protected initially by fixed payment structures, but trigger rates were hit, and lenders began demanding lump-sum payments or extended amortizations to get mortgages back on track.

Then in 2024, the Bank reversed course with five cuts, bringing the overnight rate down to approximately 3.25% by year-end. Variable-rate borrowers who stayed the course saw significant relief. Fixed-rate borrowers locked in at peak rates (4.5%–5.5% on 5-year terms in 2022–2023) are now renewing into similar rates — not the dramatic savings some expected.

Which Should You Choose in 2025?

As of early 2025, the spread between 5-year fixed and variable rates is relatively narrow — often less than 0.5%. Historically, variable has beaten fixed over full 5-year terms roughly 70% of the time. But the recent rate volatility has made many Canadians gun-shy about variable products.

Consider a variable rate if:

• You have financial flexibility (savings, investment assets) to absorb payment increases
• You believe the Bank of Canada will continue cutting rates through 2025–2026
• You may need to break your mortgage before the term ends
• You are sophisticated and comfortable monitoring rates

Consider a fixed rate if:

• You are buying at or near your maximum qualifying amount
• You cannot afford payment volatility
• You prefer certainty and peace of mind above all else
• You plan to stay in the home and keep the mortgage for the full term

The Hybrid Approach

Some lenders offer hybrid mortgages that split your balance between fixed and variable portions. This reduces your exposure to rate swings while still letting you benefit if rates fall. It is a reasonable middle-ground strategy for borrowers who are genuinely torn between the two options.
