Fixed vs Variable Mortgage in Ontario: How to Choose
"How do you feel about variable versus fixed?" It is one of the questions we hear most often from clients, especially around renewal time. The honest answer is that it comes down to your plans and how much payment movement you can live with, not only the rate. This guide explains how each option works, what it can cost to break, and what to ask before you choose.
This isn't a rate forecast. No one can promise where rates will go.
The Short Answer: It Comes Down to Your Plans
Neither option is right for everyone. A fixed rate usually suits people who value a predictable payment and a stable budget. A variable rate may suit people who can handle some movement and want more flexibility, or who think they may break their mortgage before the term ends. Your plans for the next few years, your budget and your comfort level matter more than any single rate comparison.
How Fixed Rates Work
With a fixed rate, your interest rate stays the same for the whole term, usually one to five years. Your payment stays the same too, so budgeting is simple. The trade-off is that if you need to break the mortgage early, the penalty can be larger than with a variable rate, and fixed rates often start higher than variable ones.
How Variable Rates Work
A variable rate moves with your lender's prime rate. There are two common versions:
Adjustable-rate mortgage: your payment changes when the lender's prime rate changes.
Fixed-payment variable: your payment stays the same, but the split between interest and principal changes. If rates rise, more of each payment goes to interest and less to principal.
Either way, your rate can go up or down during the term, so it is worth thinking about what you would do if your costs increased.
Break Penalties: Three Months' Interest vs IRD
Plans change, and life events such as a move, a sale or a separation can mean breaking a mortgage early. Penalties are usually calculated in one of two ways:
Three months' interest: typical for variable-rate mortgages.
The greater of three months' interest or the interest rate differential (IRD): typical for fixed-rate mortgages. The IRD can be much larger, depending on how the lender calculates it.
Lenders calculate the IRD differently, and some use posted rates in a way that can increase the penalty. Always check your own lender's terms before you sign.
Why Structure Can Matter More Than a Small Rate Difference
It is easy to focus on a rate that is a fraction of a percent lower. But the structure of the mortgage often matters just as much. That includes the penalty calculation, prepayment options, whether you can port the mortgage to a new home, and whether a line of credit can be built in. A slightly lower rate with a harsh penalty or limited flexibility may not be the better choice if your plans change.

Questions to Ask Before You Choose
How long do I expect to stay in this home?
How would my budget handle a higher payment, or a bigger share going to interest?
How is the break penalty calculated, and what would it usually look like on my balance?
Can I switch from variable to fixed later, and on what terms?
What prepayment options and portability does the lender offer?
We compare options across 30+ lenders, so you can see how different lenders handle these details side by side.
Frequently Asked Questions
Fixed or variable: which is better right now?
No option is right for everyone, and no one can reliably predict rates. We compare both against your plans and budget.
What does it cost to break a fixed vs variable mortgage?
Variable penalties are typically three months' interest. Fixed penalties can be the greater of that or the IRD, which can be much larger. Check your own lender's terms.
Can I switch from variable to fixed later?
Many lenders allow it, usually into a fixed term of equal or longer length at their rate at the time.
Does my payment change with a variable rate?
With an adjustable-rate mortgage, yes. With a fixed-payment variable, the payment stays the same while the interest and principal split changes.
