One of the most important decisions you'll make when getting a mortgage is choosing between a fixed or variable interest rate. It's a question I get asked almost daily, and the honest answer is: it depends on your personal situation, risk tolerance, and financial goals.
In this guide, I'll break down how each rate type works, the pros and cons of both, and help you think through which might be right for you in 2026.
How Fixed Rates Work
A fixed-rate mortgage locks in your interest rate for the entire term of your mortgage—typically 1 to 5 years in Canada. Your monthly payment amount stays the same regardless of what happens to interest rates in the broader economy.
How Fixed Rates Are Determined
Fixed mortgage rates are primarily influenced by the bond market, specifically Government of Canada bond yields. When bond yields rise, fixed mortgage rates typically follow. This is different from variable rates, which move with the Bank of Canada's overnight rate.
This distinction matters because fixed and variable rates don't always move in the same direction at the same time.
Advantages of Fixed Rates
- Predictability: Your payment stays the same every month, making budgeting straightforward.
- Peace of mind: You're protected from rate increases during your term.
- Easier to qualify: The mortgage stress test uses your actual rate plus 2%, rather than a minimum qualifying rate (for fixed terms of 5 years or more).
Disadvantages of Fixed Rates
- Higher initial rate: Fixed rates are typically higher than variable rates at the time of signing.
- Expensive to break: If you need to break your mortgage early, the penalty is usually an Interest Rate Differential (IRD), which can be substantial.
- No benefit from rate drops: If rates fall, you're locked into your higher rate.
How Variable Rates Work
A variable-rate mortgage has an interest rate that fluctuates based on the lender's prime rate, which tracks the Bank of Canada's overnight lending rate. Your rate is typically expressed as "prime minus X%" or "prime plus X%."
Adjustable vs. Static Payment Variable Mortgages
There are two types of variable-rate mortgages:
- Adjustable-rate mortgage (ARM): Your payment changes when rates change, so you always pay down the same amount of principal.
- Variable-rate mortgage with static payments: Your payment stays the same, but the proportion going to interest vs. principal changes. If rates rise significantly, you could hit a "trigger rate" where your payment doesn't cover the interest.
Understanding which type you're getting is important, and it's something I always clarify with clients.
Advantages of Variable Rates
- Lower initial rate: Variable rates are typically lower than fixed rates.
- Historical savings: Over the long term, variable rates have saved borrowers money more often than fixed rates.
- Lower penalties: If you break your mortgage, the penalty is typically just three months' interest—much less than an IRD penalty on a fixed mortgage.
- Benefit from rate drops: If the Bank of Canada lowers rates, your rate falls too.
Disadvantages of Variable Rates
- Uncertainty: Your rate—and potentially your payment—can change throughout your term.
- Risk of rising rates: If the Bank of Canada raises rates, your costs increase.
- Psychological stress: Some people find rate fluctuations stressful, even when they're still ahead financially.
The Break-Even Analysis
One way to think about this decision is to calculate how much rates would need to rise for the fixed rate to become the better choice. This is called break-even analysis.
For example, let's say:
- Fixed rate: 4.5%
- Variable rate: 3.8%
- Mortgage amount: $500,000
- Term: 5 years
The 0.7% difference means you'd save approximately $3,500 in the first year with the variable rate. For the fixed rate to "win," the variable rate would need to increase significantly and stay elevated for much of your term.

Who Should Consider a Fixed Rate?
A fixed rate might be right for you if:
- You're on a tight budget: If even small payment increases would strain your finances, the predictability of a fixed rate is valuable.
- You value certainty: If rate fluctuations would cause you stress, the peace of mind may be worth the premium.
- You're planning to stay put: If you're confident you'll keep the mortgage for the full term, the higher break penalty matters less.
- You believe rates will rise significantly: If you expect major rate increases, locking in now could protect you.
Who Should Consider a Variable Rate?
A variable rate might be right for you if:
- You have financial flexibility: If you could absorb a payment increase of a few hundred dollars without hardship, variable makes sense.
- You might need to break early: If there's a chance you'll move or refinance before your term ends, the lower penalty is a significant advantage.
- You're comfortable with some risk: If rate fluctuations won't keep you up at night, you could benefit from the historical savings of variable rates.
- You're planning to pay down aggressively: If you're going to make extra payments, the variable's flexibility and lower rate can accelerate your payoff.
Hybrid and Convertible Options
You don't always have to choose one or the other. Some options to consider:
Convertible Mortgages
Some variable-rate mortgages allow you to convert to a fixed rate at any point without penalty. This gives you the benefit of starting variable while having a safety net if rates start climbing.
Split Mortgages
Some lenders allow you to split your mortgage—for example, 50% fixed and 50% variable. This gives you partial exposure to both rate types.
Shorter Fixed Terms
Instead of a 5-year fixed, you could choose a 2 or 3-year fixed term. This often comes with a lower rate and lets you reassess your choice sooner.
The 2026 Interest Rate Context
Without making predictions (no one can accurately predict where rates will go), here's the context for 2026:
- The Bank of Canada makes rate decisions based on inflation, employment, and economic conditions
- Fixed rates are influenced by bond markets and can move independently of BoC decisions
- The spread between fixed and variable rates fluctuates over time
- Economic uncertainty tends to favor fixed rates in terms of pricing
The most important thing is to choose based on your personal situation, not on rate predictions.
Questions to Ask Yourself
Before deciding, consider these questions:
- How long do I realistically expect to stay in this home?
- Is there any chance I'll need to break my mortgage early (job change, growing family, etc.)?
- How would a $200-400/month payment increase affect my finances?
- Would rate fluctuations cause me significant stress?
- Am I planning to make extra payments or pay off my mortgage faster?
My Recommendation
There's no universally "right" answer. The best choice depends entirely on your personal situation. What I recommend is:
- Don't decide based on rate predictions. Even experts get interest rates wrong.
- Focus on your own financial situation. Your risk tolerance matters more than economic forecasts.
- Consider your life plans. The flexibility to break your mortgage without huge penalties can be valuable.
- Talk to a mortgage professional. I can help you run the numbers and think through scenarios.

If you're considering a refinance, this is also a great time to reassess whether your current rate type still makes sense for your circumstances.
