The Core Difference
A fixed-rate mortgage locks in your interest rate for the entire term (usually 5 years). Your payment is the same every single month. A variable-rate mortgage moves with the Bank of Canada's prime rate, when rates drop, you pay less; when they rise, you pay more.
In Canada, most people choose a 5-year term, after which you renew at whatever rate is available. The debate between fixed and variable plays out within that term.
Where Rates Stand in 2026
As of early 2026, typical rates in Ottawa look roughly like this:
- 5-year fixed: 4.3–4.9%
- 5-year variable: 4.0–4.5% (tied to prime minus a discount)
- 3-year fixed: 4.1–4.6%
Variable rates are currently close to, or only slightly below, fixed rates, which changes the calculus compared to periods when variable was significantly cheaper.
The Case for Fixed
Predictability is the main advantage. If you're a newcomer to Canada still building financial stability, or if your household budget is tight, knowing exactly what your mortgage payment will be for 5 years has real value. You can plan, save, and sleep without worrying about Bank of Canada announcements.
Fixed is generally better if:
- You're near the top of your budget
- You value stability over potential savings
- You plan to stay in the home for at least 5 years
- Interest rates seem likely to rise
The Case for Variable
Historically, variable has won. Multiple studies of Canadian mortgage data over 30+ years show that variable-rate borrowers paid less interest on average than fixed-rate borrowers. The catch: you need to tolerate short-term rate swings.
Variable is worth considering if:
- You have financial flexibility to absorb higher payments temporarily
- You might sell or refinance within 5 years (break penalties are much lower for variable)
- You believe rates will drop or stay flat
Break Penalties: The Hidden Factor
This is where variable wins decisively for flexibility. If you break a fixed mortgage early (because you sell, refinance, or need to change terms), the penalty is typically 3 months of interest for variable, but for fixed it's often the Interest Rate Differential (IRD): which can be $10,000–$30,000 on a typical Ottawa mortgage.
If there's any chance you'll move or change your mortgage in the next 5 years, variable's low break penalty is a significant advantage.
A Practical Framework
Ask yourself:
- Can my budget handle a payment increase of $300–$400/month if rates rise 1.5%?
- Do I plan to stay in this home for the full 5-year term?
- Am I more stressed by uncertainty or by potentially paying more than necessary?
If you answered yes / yes / uncertainty, fixed is probably right for you. If you answered yes / no / paying more, variable makes sense.
Ottawa-Specific Tip
Ottawa's real estate market has been relatively stable compared to Toronto or Vancouver. If you're buying a property you intend to hold long-term, the break penalty risk from fixed is lower. But if you're buying a starter condo in Centretown or Westboro and plan to upsize in 3–4 years, variable's lower exit cost is worth serious consideration.
Talk to a mortgage broker (not just your bank). They can model out both scenarios with real numbers based on your situation.
