The prime mortgage rate in Canada is the annual interest rate that major banks and lenders use to set rates for variable-rate financial products, including mortgages. As of October 2026, the typical prime rate in Canada is 4.45%. This rate is closely tied to the Bank of Canada's overnight lending rate, which directly influences borrowing costs for consumers. Understanding the prime rate is important for Canadians with variable-rate mortgages, lines of credit, or other loans, as changes to it affect their interest payments and overall financial planning.
What is the Prime Mortgage Rate?
The prime rate, also known as the prime lending rate, is the annual interest rate that Canada’s major banks and lenders use to set interest rates for variable-rate financial products. This foundational rate applies to variable-rate mortgages, home equity lines of credit, personal lines of credit, and some business loans. When a lender quotes a variable interest rate, it is typically expressed as prime plus or prime minus a specific percentage. For example, if the prime rate is 4.45% and a mortgage is offered at prime minus 1.00%, the borrower's effective mortgage rate would be 3.45%. The prime rate is not set by the government or the Bank of Canada. Each financial institution determines its own prime lending rate based on its cost of funding and market conditions. In practice, Canada's major banks usually maintain nearly identical prime rates due to similar borrowing costs and competitive pressures.
The prime rate serves as a benchmark for consumer lending, directly affecting the cost of borrowing for millions of Canadians. It is always higher than the Bank of Canada's overnight rate because lenders add a spread to account for their own funding costs, operational expenses, and lending risk. This relationship means that when the central bank changes its policy rate, commercial banks typically adjust their prime rates by a corresponding amount. The stability or volatility of the prime rate has a direct impact on household budgets, particularly for those with variable-rate debt. Understanding this rate is crucial for anyone considering a new loan, renewing a mortgage, or managing existing variable-rate credit products.
How the Prime Rate is Determined
The prime rate in Canada is determined by the interplay between the Bank of Canada's monetary policy and the individual decisions of commercial lenders. The Bank of Canada sets the target for the overnight rate, which is the interest rate at which major financial institutions borrow and lend one-day funds among themselves. This overnight rate forms the foundation for lenders' own cost of funding. Each financial institution then sets its own prime rate as a function of this funding cost, adding a margin for profit and risk. While lenders are not legally required to match Bank of Canada moves exactly, they almost always adjust their prime rates by the same amount when the overnight rate changes. When the Bank of Canada raises its overnight rate, borrowing becomes more expensive for the banks themselves, and they generally respond by increasing their prime rates to offset these higher funding costs.
Conversely, when the Bank lowers the overnight rate, lenders typically reduce their prime rates as well. This transmission mechanism usually happens within a few days of a Bank of Canada announcement. The prime rate is influenced by broader market conditions beyond just the overnight rate, including competition among lenders and their overall cost structures. Despite each bank setting its own rate, the Big Five Canadian banks typically move their prime rates in lockstep, leading to a commonly referenced Canada's prime rate. The consistency among major banks means borrowers can generally expect uniform prime rate changes across the market following a central bank decision, though there can occasionally be minor differences or delays.
Prime Rate History and Recent Trends
The prime rate in Canada has fluctuated significantly over recent years, reflecting the Bank of Canada's response to economic conditions like inflation. From early 2022 to the first half of 2023, the prime rate increased steadily during a cycle of monetary policy tightening. During this period, the Bank of Canada implemented a series of ten rate hikes, pushing its overnight lending rate to 5% by mid-2023. This aggressive tightening was a direct response to high inflation, and it caused the prime rate to rise accordingly. The historical movements of the prime rate demonstrate its sensitivity to the central bank's policy decisions aimed at managing the national economy. More recently, the prime rate has stabilized following a period of decreases.
The Bank of Canada held its overnight lending rate at 2.25% in its announcement on September 2, 2026, marking its seventh consecutive rate hold. As a result, Canada's prime rate has remained at 4.45% since October 2025, following a rate cut at that time. This period of stability has provided predictable borrowing costs for households with variable-rate mortgages and other prime-linked credit products. The table below shows key recent dates and corresponding prime rate levels, illustrating this period of holding steady after a previous cycle of increases. This history shows a clear downward trend in the prime rate from late 2024 through to late 2025, after which it has plateaued.
| Date | Prime Rate |
|---|---|
| October 30, 2025 | 4.45% |
| September 18, 2025 | 4.70% |
| March 13, 2025 | 4.95% |
| January 30, 2025 | 5.20% |
| December 12, 2024 | 5.45% |
The current prime rate in Canada is 4.45%. This rate has remained unchanged since October 2025. The prime rate is the annual interest rate that Canada's major banks and lenders use to set interest rates for variable rate financial products. Variable rate mortgages are typically quoted as prime plus or minus a certain percentage. The prime rate is closely tied to the Bank of Canada's overnight lending rate. When the Bank of Canada changes its overnight rate, most major lenders typically adjust their prime rates by the same amount.
Impact on Variable-Rate Mortgages and Other Loans
The prime rate directly dictates the interest cost for variable-rate mortgages in Canada. A variable-rate mortgage has an interest rate that is based on the lender's prime rate, plus or minus a set percentage agreed upon at the start of the term. For instance, a mortgage might be advertised with a rate based on the lender's prime rate minus a specific discount. While the interest rate fluctuates with changes to the prime rate, the borrower's regular payment amount often remains fixed for a period. When the prime rate rises, a larger portion of that fixed payment goes toward covering the increased interest, and less goes toward paying down the principal loan amount. Conversely, if the prime rate falls, more of the payment is applied to the principal, accelerating the payoff of the loan.
Significant increases in the prime rate can lead some borrowers to reach their trigger rate. The trigger rate is the point at which the borrower's regular payment no longer covers the full amount of interest accruing each month. When this occurs, the mortgage stops amortizing properly, meaning the principal balance does not decrease and may even start to increase. Lenders are required to address this situation, often by contacting the borrower to increase the monthly payment amount or to make a lump-sum payment. Beyond mortgages, the prime rate affects several other common consumer credit products. Home equity lines of credit and personal lines of credit almost always have interest rates directly tied to the prime rate. Some business loans and certain types of credit cards also use the prime rate as their benchmark, making changes to it broadly impactful across personal and commercial finance in Canada.
Comparing Fixed and Variable Mortgage Rates
When choosing a mortgage, Canadians must decide between a fixed interest rate and a variable interest rate tied to the prime rate. A fixed-rate mortgage offers stability, as the interest rate and the principal and interest payments stay exactly the same for the entire mortgage term, regardless of changes in the broader market. Borrowers can select term lengths such as 6 months, or 1, 2, 3, 4, 5, 6, 7, or 10 years. Fixed mortgage rates are not directly tied to the prime rate. Instead, they generally respond to movements in Government of Canada bond yields. Lenders often offer a rate hold for fixed-rate mortgages, allowing a pre-approved borrower to lock in a specified rate for a set period, commonly 120 days, even if market rates rise during that time.
A variable interest rate mortgage means the rate is based on the lender's mortgage prime rate, which can go up and down over the term of the loan. With a standard variable-rate mortgage, the payment amount typically remains constant, but the allocation between interest and principal changes with rate movements. Another common structure is the adjustable-rate mortgage, where the payment itself changes when the prime rate changes. The choice between fixed and variable involves weighing the security of a fixed payment against the potential savings of a lower initial variable rate. It is important to understand that variable rates introduce uncertainty, as future payments or amortization schedules depend on the path of the Bank of Canada's overnight rate and the lender's subsequent prime rate adjustments. Borrowers must assess their own risk tolerance and financial stability when making this key decision.
Common Features and Borrower Considerations
Mortgage products in Canada, whether fixed or variable, often come with standard features that borrowers should understand. Prepayment privileges are a common feature, allowing borrowers to pay down their mortgage faster without penalty. On closed mortgages, lenders typically allow annual prepayments of up to 10-20% of the original principal amount. Open mortgages allow for unlimited prepayment but usually come with a higher interest rate. Another feature is the ability to skip a payment under certain conditions. For example, some lenders permit borrowers to skip the equivalent of one monthly payment per year if needed. These flexibilities can help borrowers manage cash flow and pay off their mortgages sooner, providing valuable financial control.
For borrowers with variable-rate mortgages, monitoring the prime rate and understanding their contract are essential. Key considerations include knowing the exact formula for their rate, such as prime minus a specified discount, and understanding what happens if rates rise substantially. Borrowers should be aware of their trigger rate and the steps their lender will take if it is reached. It is also important to recognize that while the prime rate from major banks is usually uniform, some smaller lenders or alternative mortgage providers may have slightly different prime rates. When shopping for a variable-rate product, the discount or premium relative to prime is a critical figure to compare, as is the lender's history of adjusting its prime rate in line with Bank of Canada announcements. Thoroughly reviewing all contract terms before signing is the best way to avoid surprises related to payment changes, prepayment charges, or renewal conditions.
Frequently asked questions
What is Canada's prime rate today?
As of October 2026, Canada's prime rate is 4.45%. This rate has remained at this level since October 2025, following a cut by the Bank of Canada. The prime rate is the benchmark interest rate that major banks use to set rates for variable loans like mortgages and lines of credit. It is directly influenced by the Bank of Canada's overnight lending rate, which is currently 2.25%.
Who sets the prime rate in Canada?
Each financial institution sets its own prime rate. The prime rate is a function of a bank's cost of funding, which is influenced by the target for the overnight rate set by the Bank of Canada. Canada's major banks typically move their prime rates in lockstep, so there is a commonly referenced national prime rate. The prime rate is not directly set by the Bank of Canada or the government.
How does the Bank of Canada rate affect the prime rate?
Changes to the Bank of Canada's overnight rate typically lead to corresponding changes in the prime rate. Lenders use the overnight rate as a foundation for their own borrowing costs. When the Bank of Canada raises or lowers its overnight rate, Canada's major banks generally adjust their prime rates by the same amount within a few days. The prime rate is always higher than the overnight rate because lenders add a spread to account for funding costs, operational expenses, and lending risk.
What is the difference between a fixed and variable mortgage rate?
A fixed mortgage rate stays the same for the entire term of the mortgage, providing payment stability. A variable mortgage rate is tied to the lender's prime rate, so it can fluctuate. Variable rates are typically quoted as prime plus or prime minus a percentage. Fixed rates are influenced by bond yields, while variable rates move with the prime rate.
What happens to my variable mortgage if the prime rate goes up?
If the prime rate increases, the interest rate on your variable mortgage will also increase. For a variable rate mortgage, your interest rate is based on the lender's prime rate. If rates rise significantly, some borrowers may eventually reach their trigger rate. When the trigger rate is reached, the regular payment may no longer cover enough interest to keep the mortgage amortizing properly. Lenders may then require borrowers to increase their payments or switch to a different payment structure.
How long can I hold a mortgage rate?
Lenders commonly offer a rate hold period for a specified mortgage rate for a set period of time. A typical rate hold for a pre approved mortgage lasts for 120 days. This rate hold applies to fixed rate mortgages, since the interest rate of variable rate mortgages can fluctuate. The rate hold guarantees the interest rate on your pre approval term for up to 120 days, even if general market interest rates go up.
