If you have a variable-rate mortgage, a home equity line of credit (HELOC), or a personal line of credit, one number quietly controls how much interest you pay every month: the Canadian prime rate. Right now, that rate sits at 4.45% (as of October 7, 2026), down sharply from the 7.20% peak of mid-2023, but not something you can afford to ignore.
This guide breaks down exactly what the prime rate is, how it is set, why it moves, and what it means for your borrowing costs today.
What Is the Prime Rate in Canada?
The prime rate (sometimes called the prime lending rate) is the baseline annual interest rate that Canadian banks and lenders use to price variable-rate credit products. It is not a government-mandated rate. Each financial institution sets its own, but in practice the Big Six banks move in lockstep because they face virtually identical funding costs.
When a lender quotes you a variable mortgage at “prime minus 0.75%” or a line of credit at “prime plus 3.00%,” they are anchoring your actual rate to this number. That means every time the prime rate shifts, your interest charges shift with it.

The prime rate has not changed since it followed the Bank of Canada’s October 29, 2025 cut, the last of nine rate cuts between June 2024 and October 2025.
How the Bank of Canada Sets the Stage
The prime rate is not set by the Bank of Canada directly. But the central bank’s overnight rate (the rate at which financial institutions lend money to one another for one-day periods) is the engine that drives it.
When the Bank of Canada raises or lowers its overnight rate, commercial banks almost always follow with an identical adjustment to their prime rate within days. The spread between the two has remained consistent at approximately 2.20 percentage points for many years.

So the math is straightforward:
- Overnight rate (2.25%) + Typical spread (2.20%) = Prime rate (4.45%)
The Bank of Canada meets eight times per year to review and potentially adjust the overnight rate. These are called fixed announcement dates. Any change to the overnight rate on those dates typically triggers an equivalent prime rate move at major banks within 48 hours.

Why the Prime Rate Changed So Dramatically (2022 to 2026)
To understand where the prime rate is today, it helps to see where it has been.
| Date | Bank of Canada Rate | Prime Rate |
|---|---|---|
| February 2022 | 0.25% | 2.45% |
| July 2023 | 5.00% | 7.20% |
| June 2024 | 4.75% | 6.95% |
| December 2024 | 3.25% | 5.45% |
| October 2025 | 2.25% | 4.45% |
| September 2026 | 2.25% (held) | 4.45% (unchanged) |

Starting in early 2022, the Bank of Canada launched an aggressive rate-hike campaign to bring inflation under control. The overnight rate went from a pandemic-era low of 0.25% all the way to 5.00% by July 2023. That pushed the prime rate to 7.20%, the highest it had been in over a decade.
Then the direction reversed. Between June 2024 and October 2025, the Bank cut rates nine times as inflation retreated toward its 2% target. The overnight rate is now back at 2.25%, and the prime rate has settled at 4.45%. At the Bank’s September 2, 2026 announcement, rates were held steady for the seventh consecutive meeting.
How the Prime Rate Affects Your Borrowing
The prime rate does not touch every loan equally. Here is how it flows through the most common types of credit.
Variable-Rate Mortgages
Variable-rate mortgages are the product most directly exposed to prime rate changes. There are two main types:
- Adjustable-rate mortgages (ARMs): Your monthly payment changes whenever the prime rate moves. If prime goes up, your payment goes up.
- Fixed-payment variable mortgages: Your payment stays the same, but the split between principal and interest shifts. When rates rise, more of your payment goes to interest and less to paying down the balance.
If you have a fixed-payment variable mortgage and rates rise significantly, you may eventually hit a trigger rate: the point at which your static payment no longer covers the interest portion. At that point, lenders typically require a payment increase or a mortgage restructure.
Home Equity Lines of Credit (HELOCs)
HELOCs are almost always priced at prime plus a margin (often prime plus 0.50%). If the prime rate rises 0.25%, your HELOC rate rises 0.25% immediately, with no grace period. On a $100,000 HELOC balance, a quarter-point increase adds roughly $21 per month in interest costs.
Personal Lines of Credit
Unsecured personal lines of credit typically carry rates of prime plus 3% to prime plus 8%, depending on your credit profile and lender. At today’s prime of 4.45%, a borrower at prime plus 5% is paying 9.45% on their balance. Understanding how that rate can shift is important if you are carrying a balance long term. If you are comparing your options, personal loans in Canada offer an alternative with a fixed rate and predictable monthly payments.
Credit Cards
Most credit cards carry fixed rates that do not change with the prime rate. However, some variable-rate cards exist, so read your cardholder agreement carefully. Low-interest credit cards sometimes reference prime in their rate disclosures.
Other Loans and Business Credit
Many business lines of credit, agricultural loans, and some auto loan products are also priced off prime. The principle is the same: when prime moves, so does your rate.
Fixed vs. Variable: What the Prime Rate Debate Really Means
One of the most common questions Canadians face when taking on new debt is whether to choose a fixed rate or a variable rate. Understanding the prime rate is central to answering that.
Fixed-rate products lock in an interest rate for a set term (commonly 1 to 5 years for mortgages). Your payments do not change no matter what happens to the prime rate. You get predictability in exchange for paying a small premium over what a variable rate might start at.
Variable-rate products move with the prime rate. When the Bank of Canada is cutting rates (as it was from June 2024 to October 2025), borrowers with variable products benefit automatically. But when rates rise, those same borrowers take the full impact.
Historically, variable-rate borrowers have paid less interest over the long run in Canada, but the 2022-2023 rate hike cycle was a painful reminder that there are periods when fixed beats variable. The right choice depends on your financial cushion, your timeline, and how much payment volatility you can absorb.
What Happens When the Prime Rate Changes?
When the Bank of Canada adjusts its overnight rate, here is the typical sequence:
- Bank of Canada announcement (9:45 a.m. ET on a fixed announcement date)
- Major banks respond: usually within 24 to 48 hours, updating their prime rate on their websites and in their systems
- Variable-rate products adjust: your lender applies the new rate to your balance, either changing your payment or adjusting the interest/principal split
- New mortgage quotes reflect the change: lenders reprice their variable-rate offers immediately
The key thing to track is not the daily news but the Bank of Canada’s fixed announcement schedule. The remaining rate decisions in 2026 are on October 28 and December 9.
What Should Borrowers Do?
The prime rate affects different people in different ways. Here are practical actions based on your situation.
If you have a variable-rate mortgage: Review your trigger rate (if you have a fixed-payment variable mortgage) and know how much room you have before a rate increase would require a payment adjustment. If rates have come down since you took out your mortgage, consider speaking with your lender about whether breaking and re-locking at a lower fixed rate makes sense, factoring in any penalty costs.
If you are applying for a new loan or mortgage: Think carefully about whether the current prime rate environment favours fixed or variable. With the overnight rate at its lowest level since July 2022, and unchanged since the Bank of Canada’s October 2025 cut, getting a fixed rate now while rates are relatively low is a reasonable hedge.
If you have a HELOC or line of credit: Consider what would happen to your monthly costs if the prime rate rose by 0.50% to 1.00%. If that would strain your budget, a plan to pay down the balance or convert a portion to a fixed-rate loan is worth exploring.

Frequently Asked Questions
Canada’s major banks set prime about 2.20 percentage points above the Bank of Canada’s overnight rate. It normally moves only after one of the Bank’s eight scheduled announcements, usually within 24 to 48 hours, so your lender’s posted rate or the Bank of Canada’s weekly prime figure gives you today’s number.
It means your interest rate is one percentage point above your lender’s prime rate. If prime is 4.45%, prime plus 1 is 5.45%. The rate is variable, so when your lender’s prime moves after a Bank of Canada decision, your rate moves by the same amount, and so does the interest on your balance.
In practice, only after the Bank of Canada cuts its overnight rate, which no one can know in advance. Banks then almost always lower their prime by the same amount within days. The Bank’s moves follow inflation: it cut nine times between June 2024 and October 2025 as inflation eased toward its 2% target.
