TL;DR: The Bank of Canada sets a policy interest rate about eight times a year. It does not set your mortgage rate directly. Variable-rate mortgages react fast because lenders move their prime rate when the policy rate changes. Fixed-rate mortgages react to the bond market, which moves on what investors expect will happen next. If you are renewing or refinancing, the best move is to understand which type of rate affects you and watch the trend, not just the latest headline.
Every few weeks, the news announces that the Bank of Canada raised, cut, or held its rate — and borrowers across Ontario see their mortgage offers shift in ways that do not always match the headline. The policy rate is the most talked-about number in Canadian mortgages, and one of the most misunderstood. This guide explains what it actually is and how it reaches your monthly payment.
What is the Bank of Canada policy rate, exactly?
The policy rate is the interest rate the Bank of Canada uses to influence borrowing costs across the economy. It is not your mortgage rate. Think of it as the Bank’s main tool: when the Bank raises it, borrowing gets more expensive and the economy cools down; when it lowers it, borrowing gets cheaper and spending picks up.
The Bank sets this rate at scheduled meetings, roughly eight times a year, based mainly on inflation. When prices rise too fast, the Bank usually raises the rate to cool spending; when the economy is weak, it lowers the rate to encourage it.
Here is the key point: the Bank of Canada does not set the rate on your mortgage. Your lender does. But lenders watch the Bank’s rate closely, because it sets the cost of money for everyone, including them.
Why do variable mortgage rates move when the policy rate moves?
Because variable rates are tied to your lender’s prime rate, and lenders move prime when the Bank of Canada moves the policy rate.
When the Bank of Canada moves the policy rate, most lenders move their prime rate by the same amount, usually within a day or two. Your variable-rate mortgage is written as “prime minus (or plus) a discount” — so when prime moves, your rate moves with it. The change is fast and direct.
There are two common ways variable mortgages handle this:
- Adjustable payments. Your monthly payment changes when the rate changes. Your budget feels the move right away.
- Fixed payments. Your payment stays the same, but more of it goes to interest and less pays down your balance. If rates rise a lot, you may hit the “trigger point” — the payment no longer covers the interest, and you could owe more than expected at renewal.
Why do fixed mortgage rates seem to move on their own schedule?
Because fixed rates are priced off the bond market, not the Bank of Canada’s decisions — and the bond market moves on expectations, not announcements.
This is the part that surprises most borrowers. A fixed mortgage locks your rate for the whole term. Lenders fund those fixed loans by raising money in the bond market, so they price fixed mortgages based on what it costs them there — typically government bond yields with a similar term length.
Bond investors are always looking ahead. When they believe the Bank of Canada will raise rates in the future, they demand higher returns now. Fixed mortgage rates rise before the Bank does anything. When investors believe cuts are coming, fixed rates can fall while the Bank is still holding steady.
That is why you sometimes see headlines like “the Bank held rates, but mortgage rates went up.” The bond market is reacting to hints about the future — speeches, economic reports, inflation data — not just the decision itself.
For renewal clients, this matters more than anything else in this guide: the fixed rate on your renewal letter reflects what the market expects, which can change between the day you receive the letter and the day you sign. A fixed-rate offer that looked fine three months ago may look very different today, or vice versa.
How does all of this affect a renewal or refinance?
At renewal, the rate environment you are walking into decides your payment — and understanding the mechanism helps you time and compare better.
A few months before your term ends, your lender sends a renewal offer. Many borrowers sign it without shopping around — an expensive habit, because your current lender is betting you will not compare.
Refinancing replaces your mortgage — usually to pull out equity, consolidate debt, or get better terms — and follows the same rules: variable tracks prime, fixed tracks the bond market. But refinancing can trigger a penalty for breaking your term. A mortgage calculator can model the payment, but have a broker review the penalty math before you commit.
Three practical tips for renewal and refinance clients:
- Start early. Lenders will let you renew up to 120 days before your maturity date, and brokers can usually hold a rate for about that long. Starting early gives you room to watch the trend instead of signing under pressure.
- Know which rate type you hold. If you are variable, watch Bank of Canada announcements. If you are shopping for a fixed rate, watch the bond-market trend — which a broker follows daily.
- Do not sign the first offer. Your renewal letter is an opening offer, not a final price. Comparing lenders regularly saves borrowers real money, especially in a moving rate environment.
If your situation does not fit a standard bank file — bruised credit, self-employment income, or a property a bank will not touch — private mortgage options exist in Ontario with their own rate structure. You can read more on private mortgages in Ontario to see how those work.
What should I actually watch if I want to follow this?
Watch the trend in fixed rates for buying decisions, and watch Bank of Canada announcements for variable-rate payments.
You do not need to become an economist. For fixed-rate shoppers, the useful signal is whether mortgage rates are drifting up or down over weeks — that trend comes from the bond market and tells you whether waiting or locking in is smarter. For variable-rate holders, the signal is simpler: the Bank of Canada’s next scheduled decision, and whether your payment will adjust.
No one can predict the exact path of rates — treat confident headlines as opinion, not fact. The right strategy is understanding the mechanism so you can react quickly when conditions change.
Borrowers in Ontario also benefit from knowing the rules that protect them during this process — for example, how Ontario private mortgage rules work, and why renewing or refinancing with the right timing matters.
Does the Bank of Canada set my mortgage rate directly?
No. The Bank sets the policy rate, which influences the cost of borrowing across the economy. Your lender sets your mortgage rate based on that environment, plus its own costs and margins.
Why did my variable rate change but my neighbour’s fixed rate stayed the same?
Variable rates are tied to the lender’s prime rate, which moves when the Bank of Canada moves the policy rate. Fixed rates are tied to the bond market and only change when a new mortgage or renewal is priced. Your neighbour’s rate will move when their term ends.
Can fixed mortgage rates change before a Bank of Canada decision?
Yes — this happens often. The bond market prices in expectations about future decisions, so fixed rates can rise or fall weeks before the Bank announces anything.
How far ahead of my renewal should I start shopping?
Start about four months before your maturity date. That is how early lenders and brokers can typically lock in a rate for you, and it gives you time to compare offers calmly instead of signing your lender’s first letter.
I am worried my renewal payment will be much higher. What can I do?
Compare lenders instead of signing your first renewal offer, reconsider whether variable or fixed suits you now, and talk to a broker early — extending amortization, restructuring debt, or switching lenders may all be options.
