Choosing between a fixed and variable mortgage is not simply about finding the lowest rate today.
The better question is: 𝗪𝗵𝗶𝗰𝗵 𝗺𝗼𝗿𝘁𝗴𝗮𝗴𝗲 𝗳𝗶𝘁𝘀 𝘆𝗼𝘂𝗿 𝗯𝘂𝗱𝗴𝗲𝘁, 𝗳𝘂𝘁𝘂𝗿𝗲 𝗽𝗹𝗮𝗻𝘀 𝗮𝗻𝗱 𝗰𝗼𝗺𝗳𝗼𝗿𝘁 𝘄𝗶𝘁𝗵 𝗿𝗶𝘀𝗸?
A lower starting rate can look attractive, but it may not remain lower. A fixed rate can provide peace of mind, but that stability may come at a higher price. Here is what Canadian homebuyers and homeowners should understand before making a decision in 2026.

What Is a Fixed-Rate Mortgage ?

With a fixed mortgage, your interest rate stays the same for the entire mortgage term.
If you choose a five-year fixed mortgage, for example, your rate will not change during those five years. Your regular principal-and-interest payment will also remain predictable.
A fixed mortgage may make sense if:

The main disadvantage is that fixed mortgages can have higher penalties if you sell, refinance or break the mortgage before the term ends. Depending on the lender and contract, that penalty could cost thousands of dollars.

What Is a Variable-Rate Mortgage?

With a variable mortgage, your interest rate can move up or down during your term.
Variable mortgage rates are normally connected to the lender’s prime rate, which is influenced by changes to the Bank of Canada’s policy rate. If rates fall, you may pay less interest. If rates rise, your costs may increase.
A variable mortgage may make sense if:

Some variable mortgages have payments that rise or fall with the rate. Others keep the payment fixed but change how much goes toward interest and principal. If rates rise far enough, you may reach a trigger point where the lender requires a larger payment.
Make sure you know 𝗲𝘅𝗮𝗰𝘁𝗹𝘆 which type of variable mortgage you are being offered.

Which One Could Cost Less?

There is no honest way to guarantee which option will cost less over the next three or five years.
A variable mortgage could save you money if rates fall and remain lower. But if rates increase—or stay higher longer than expected—the expected savings may disappear.
A fixed mortgage protects you from rate increases during your term. However, you may end up paying more if variable rates fall after you lock in.
That is why choosing a mortgage based only on an interest-rate forecast is risky. Even professional economists cannot predict every Bank of Canada decision or economic change.

The Real Question: How Much Risk Can You Afford?

Imagine that your mortgage payment increased by $200 or $300 per month.
Would that be manageable, or would you need to use credit cards, reduce your savings or struggle with other bills?
If a moderate payment increase would create serious pressure, a fixed mortgage is likely the safer choice. If you have stable income, emergency savings and room in your budget, a variable mortgage may be worth considering.
Your mortgage decision should also account for possible life changes. Are you planning to move, start a family, change jobs, open a business or refinance in the next few years? A mortgage with a slightly lower rate may not be the better deal if it comes with expensive penalties or restrictive conditions.

Don’t Compare Only the Rate

Before signing, compare:

The mortgage with the lowest advertised rate is not automatically the mortgage with the lowest total cost.

The Bottom Line

Choose fixed if you value predictable payments and protection from sudden rate changes.
Consider variable if you can comfortably manage uncertainty and want the opportunity to benefit if rates fall.
Most importantly, choose based on your real financial situation—not a headline, a friend’s decision or someone’s rate prediction.
Before committing, ask your mortgage professional to show you both options using your actual mortgage amount. Compare the payments, possible penalties and what would happen if rates moved up or down. That conversation could save you far more than simply chasing the lowest rate.
