How a 5-year variable mortgage rate works in Canada
A "5-year" mortgage in Canada refers to the term — the length of time your rate and conditions are locked in with the lender. A 5-year variable rate means your term is five years, but the interest rate can change during that term. Most Canadian variable mortgages are priced as a lender's prime rate minus a discount (for example, prime minus 1.10%). Because lender prime rates usually move when the Bank of Canada changes its overnight target rate, a variable rate can drift up or down while you are in the term.
There are two common structures. With a variable-rate mortgage (VRM), your regular payment typically stays the same when prime changes, but the portion going to interest versus principal shifts. With an adjustable-rate mortgage (ARM), your payment itself can adjust when prime moves. Either way, the rate you start with is not guaranteed to be the rate you finish with.
Current rate backdrop ahead of September 2, 2026
The Bank of Canada's policy-rate page shows the target overnight rate at 2.25%, held through the summer of 2026, with the next scheduled rate decision on September 2, 2026. This matters most for variable-rate mortgages: when the Bank moves its rate, lenders generally adjust prime, and variable rates reprice with it. A hold leaves variable rates roughly where they are; a cut would tend to lower them; an increase would tend to raise them.
Fixed 5-year rates do not move directly with a Bank of Canada decision. Lenders price fixed terms largely from Government of Canada bond yields and their own funding and competition, so a BoC hold or cut can still influence fixed pricing indirectly through bond markets. That is why, in late-August 2026 snapshots, the best high-ratio 5-year variable (about 3.35%) sat below the best high-ratio 5-year fixed (about 4.09%), yet both can shift for different reasons.
Variable vs fixed: what the September 2026 snapshot shows
| Factor | 5-year variable | 5-year fixed |
|---|---|---|
| Best high-ratio snapshot (Aug 29, 2026) | ~3.35% (Ratehub) | ~4.09% (Ratehub) |
| What moves it | Lender prime rate, which follows Bank of Canada decisions | Government bond yields and lender pricing |
| Payment certainty | Lower starting rate, but payment or principal/interest split can change | Rate and payment fixed for the full term |
| Best fit | Borrowers who expect rates to fall or can absorb payment movement | Borrowers who want predictability and budget stability |
| Key risk | Prime rises and the cost increases over the term | You lock in a higher rate if fixed pricing is elevated at signing |
These figures are public comparison snapshots, not approvals. Your actual rate depends on insurer category (insured, insurable or uninsured), down payment or equity, amortization, property use, credit and documentation. Always compare your specific scenario rather than the advertised headline.

Start a rate checkWhat to weigh before choosing a 5-year variable rate
- Check today's Canadian mortgage rates by term and rate type, including how variable compares with fixed.
- Use a mortgage payment calculator to model a variable rate and a higher "stress" rate, so you see the payment range you could face.
- Ask lenders or a broker about the discount to prime, whether the mortgage is a VRM or ARM, and how payments adjust if prime rises.
- Review mortgage renewal rates if you are renewing, since many 2025–2026 renewers are comparing fixed and variable offers.
- Consider your budget flexibility: could you still manage the payment if prime rose by 0.50%–1.00% over the term?
- Do not choose only by the lowest advertised rate; contract features such as prepayment privileges, portability and penalties can matter if you sell, refinance or make extra payments.

Frequently asked questions
What is a 5-year variable mortgage rate in Canada?
A 5-year variable mortgage has a fixed five-year term, but the rate is typically lender prime minus a discount. As prime changes with Bank of Canada decisions, the rate can move during the term, which can change your payment or the principal-versus-interest split of each payment.
How does the Bank of Canada decision affect 5-year variable rates?
When the Bank of Canada changes its overnight target rate, lenders usually adjust prime, and variable mortgage rates move with it. The Bank held its policy rate at 2.25% through summer 2026, with the next decision on September 2, 2026. A change on that date would directly affect new and adjustable variable-rate mortgages.
Are 5-year variable rates lower than 5-year fixed in September 2026?
Late-August 2026 snapshots show the best high-ratio 5-year variable near 3.35% versus the best high-ratio 5-year fixed near 4.09% (Ratehub, August 29, 2026). Variable can start lower, but it can rise if prime increases. Actual offers depend on qualification, insurer category and lender.
Should I choose a 5-year variable or fixed mortgage in 2026?
There is no single right answer. Fixed gives payment certainty for the term; variable can start lower but adds rate-movement risk. The better fit depends on your risk tolerance, budget flexibility, plans to sell or refinance, and how a payment change would affect your household. This is educational information, not personalized advice.
How is a 5-year variable mortgage payment calculated?
The payment is based on the current variable rate applied to your balance and remaining amortization. With a VRM the payment often stays the same when prime changes but the principal/interest split shifts; with an ARM the payment itself can adjust. Use a mortgage payment calculator to model different rates before committing.
