How Bank of Canada Rate Cuts Affect Your Mortgage

By Bonnie Thorlakson, Mortgage Specialist — Kelowna, BC

What Is the Bank of Canada Policy Rate?

The Bank of Canada meets eight times per year to review and set its policy rate. Rate decisions are made based on inflation data, economic growth, employment, and global financial conditions. When inflation is high, the Bank raises rates to cool the economy. When inflation is under control and growth needs a boost, rates are cut.

Between March 2022 and July 2023, the Bank raised its rate from 0.25% to 5.00% — the most aggressive rate hiking cycle in Canadian history. Beginning in June 2024, the Bank began cutting rates as inflation moved closer to its 2% target. By late 2024, the overnight rate had fallen to 3.25%.

Variable Rate Mortgages: Immediate Impact

If you have a variable rate mortgage, a Bank of Canada rate cut affects you directly and quickly.

Variable rate mortgages are priced at prime rate plus or minus a set spread (e.g., prime minus 0.50%). Canada’s prime rate moves in lockstep with the Bank of Canada overnight rate — when the Bank cuts by 0.25%, prime drops by 0.25%, and so does your variable mortgage rate.

Two Types of Variable Rate Mortgages

• Variable rate, variable payment: Your actual monthly payment adjusts when prime rate changes. A rate cut lowers your payment immediately. This type of mortgage was less common historically but has become more prevalent.
• Variable rate, fixed payment (the most common type in Canada): Your payment stays the same when rates change, but the split between interest and principal adjusts. A rate cut means more of each payment goes to principal instead of interest — you pay down your mortgage faster, but your cheque amount doesn’t change until renewal.

Fixed Rate Mortgages: No Immediate Impact

If you have a fixed rate mortgage, a Bank of Canada rate cut has no direct impact on your current payment or rate. Your rate is locked in for the duration of your term regardless of what the Bank does.

However, rate cuts do affect fixed rate mortgages indirectly, because fixed rates are priced based on Government of Canada bond yields — specifically the 5-year bond. When the Bank cuts rates, bond yields often (but not always) fall too, which can pull fixed mortgage rates lower over time.

The relationship is not instant or one-to-one. Bond markets respond to expectations of future rate cuts, not just the cuts themselves. Fixed rates can begin moving before a formal rate cut announcement if markets have priced in the expectation.

HELOCs: Immediate and Direct

A Home Equity Line of Credit (HELOC) is almost always priced at prime rate (sometimes prime plus a margin). Like variable rate mortgages, HELOC interest charges drop immediately when the Bank of Canada cuts rates. If you carry a significant HELOC balance, rate cuts can meaningfully reduce your monthly interest cost.

Does a Rate Cut Mean Now Is the Time to Buy?

Not automatically. Rate cuts tend to stimulate housing demand — lower borrowing costs mean more buyers can qualify and afford more. This can push prices upward, which may partially or fully offset the benefit of the lower rate.

The Bank of Canada itself flagged this concern in 2024, noting that faster rate cuts could reignite housing markets before supply conditions improved. This dynamic means rate cuts are not a simple signal to rush into the market — timing a purchase around rate movements is generally less important than having the right financial foundation in place.

Should You Lock In or Stay Variable?

This question comes up at every renewal and every rate cycle. There is no universal right answer, but here are the relevant considerations:

Arguments for going (or staying) variable:

• If the Bank of Canada is in a rate-cutting cycle, variable rates will move lower over time, potentially saving more than a fixed rate would
• Variable rates have historically outperformed fixed rates over most long-term periods in Canada, because fixed rates price in a risk premium
• If you have financial flexibility and can absorb payment variability, variable rates reward patience

Arguments for fixing:

• Certainty. A fixed rate lets you budget with precision. For households where payment variability is genuinely stressful or risky, this matters
• If rates reverse direction and begin rising again, a fixed rate protects you for the duration of your term
• If fixed rates have already dropped significantly in anticipation of cuts, locking in before further market volatility can capture that advantage

What Happens to Mortgage Rates After a Rate Cut?

After a Bank of Canada rate cut:

1. Prime rate drops within a day or two, usually by the same amount as the overnight rate cut
2. Variable rate mortgages and HELOCs adjust to reflect the new prime rate
3. Fixed rates may or may not move, depending on what bond markets do
4. Lenders may adjust their posted and special-offer fixed rates based on their own funding costs and competitive positioning

None of this happens in isolation. A mortgage specialist watches the market closely and can tell you when conditions are particularly favourable for locking in or when holding variable makes sense given the trajectory.
