Meta description: The Bank of Canada moves rates and your mortgage payment changes. Here is what a 0.25% move means in real dollars for Canadian variable and fixed mortgages.
If you have a mortgage in Canada, you have probably noticed that every Bank of Canada announcement gets a lot of press. What is harder to figure out is what it actually means for your monthly payment. The headlines talk about basis points. You pay dollars. Let us translate.
The Bank of Canada sets its overnight rate, the rate at which major banks lend to each other overnight. It announces decisions eight times a year, roughly every six weeks, with the specific dates published in advance. When the Bank raises, holds, or cuts this rate, your bank's prime rate moves in lockstep, usually the next business day.
Prime rate is what your variable mortgage is based on. A typical Canadian variable rate is written as "prime minus X", for example prime minus 0.80%. The Bank does not set your mortgage rate directly. It sets the overnight rate, your bank sets prime relative to that, and your rate is prime minus your discount.
Fixed rates are different. They are priced off the bond market, mainly 5-year Government of Canada bond yields, not the overnight rate. When the Bank cuts, fixed rates often fall a little too, but there is no guaranteed one-to-one move.
Most Bank of Canada moves are 0.25%. Here is what that means on a variable mortgage, using a $400,000 balance, 25 years remaining, and a starting rate of 5.00%:
At 5.00%, the monthly payment is about $2,333. After a 0.25% cut to 4.75%, it drops to about $2,275. That is roughly $58 per month, or about $700 per year.
Scale it up and down for your balance: a $300,000 mortgage moves about $43 per month on a quarter point, and a $600,000 mortgage moves about $87 per month. An easy rule of thumb is that a 0.25% change moves your payment by roughly $14 to $15 per month for every $100,000 of mortgage balance.
On a 1% total move across a full year of decisions, the same $400,000 mortgage would change by about $232 per month, or nearly $2,800 per year. That is real money, and it is why rate decision days matter if you are on variable.
Not all variable mortgages react the same way. It depends on the type:
Adjustable-rate mortgages (ARM). Your payment changes right away when prime changes. A cut shows up in your next payment as a lower amount.
Variable-rate mortgages (VRM) with fixed payments. Your payment stays the same, but the split between principal and interest changes. A rate cut means more of each payment goes to principal, so you pay the mortgage off faster without the monthly number moving.
Know which one you have before rate decision day. If your payment is fixed on a variable product, a cut does not lower your monthly bill, but it shortens your amortization. That is still worth real money: on that $400,000 mortgage at 5.00%, a permanent 0.25% cut taken as extra principal paydown trims months off the life of the loan and saves thousands in interest.
There is one scenario worth knowing about. If you have a fixed-payment variable mortgage and rates rise enough that your payment no longer covers the monthly interest, you hit what is called the trigger rate. Past that point, your payment does not even cover the interest, so your balance starts growing.
Most banks respond by raising your payment, often automatically, sometimes to a specified minimum. A few people in 2022 and 2023 saw their amortization stretch past 40, 50, even 60 years on paper before their lender stepped in. If your amortization has quietly stretched far past its original term, that is worth a phone call to your lender before the next announcement.
If you locked in a fixed rate, a Bank of Canada decision does not change your payment at all. Your rate is your rate until renewal.
But decisions still matter to you at renewal time. Banks tend to adjust fixed rates partly in anticipation of where the Bank is heading, and partly based on bond yields. A Bank that is clearly cutting can pull fixed rates down gradually, which matters when you shop your renewal. This is also where penalties come in: if you want to break a fixed mortgage mid-term to grab a lower rate, your IRD (interest rate differential) penalty shrinks as rates fall. Run the penalty math before you act, because the savings have to clear the penalty to make the break worthwhile.
Mostly, no. The Bank publishes its schedule in advance, and bond markets price in expected moves before they happen. If everyone expects a 0.25% cut on a Wednesday, fixed rates and variable discounts have already moved to reflect it. You cannot reliably outsmart the market by waiting for announcement day.
What you can do:
A 0.25% Bank of Canada move is about $58 a month on a $400,000 variable mortgage, and about $230 a month for a full point. Fixed-rate payments do not budge, but renewal shopping and break penalties get friendlier as the Bank cuts. Do not try to time announcements. Hold a rate, know your trigger rate, and budget a point above where you are.
