The Prime Rate in Canada
Why Does it Matter to Mortgage Borrowers?
Canadian mortgage borrowers have experienced stress in recent years due to increasing interest rates. News headlines commonly refer to the prime rate, noting the periodic changes in interest rates from the Bank of Canada, its impact on the prime rate and the impact it has on variable-rate mortgage borrowers. Recently the prime rate has been declining. This is good news but, as a mortgage borrower, do you understand how the prime rate affects you?
What is the prime rate?
The prime rate in Canada as of October 29, 2025 is 4.45%.
The prime rate is most commonly defined as the interest rate commercial banks charge their most credit-worthy customers. It serves as a benchmark rate for setting the rates on a variety of financial products, including mortgages, personal loans, and lines of credit. The prime rate is influenced by a number of factors, including inflation, economic growth, and the supply and demand for credit.
The prime rate is determined by the banks themselves, and it is typically set at a level that is 1.5 to 2.5 percentage points above the overnight lending rate (aka: the Policy Rate) set by the Bank of Canada.
The current prime rate appears high to us today, partly due to the fact that is has been unusually low over the past decade. The average Prime Rate over the past 50 years is 7.18%, higher than today. However, the average over the past 20 years is 3.75%. Compared to more recent history, the prime rate is a bit high at 4.45%.
How is the prime rate determined?
The Bank of Canada's monetary policy is a key determinant of the prime rate even though it does not directly set the rate. The Bank of Canada uses its benchmark overnight lending rate to regulate the nation's economic growth and restrain inflation. The Bank of Canada influences short-term interest rates by adjusting the target for the overnight rate. They make eight rate announcements each year, sometimes changing rates and sometimes keeping them unchanged. When the Bank of Canada changes their policy rate, the prime rate charged by banks changes as well. The dates when they have changed rates and the impact on the prime rate are below:

|---|---|---|
| Oct 2025 | 4.45% | -0.25% |
| Sep 2025 | 4.70% | -0.25% |

There are times, such as when the Covid outbreak began, that the Bank of Canada may meet more frequently to set rates. They did so three times in March 2020.
When the Bank of Canada changes the overnight rate, the Canadian banks usually change their prime rates within a couple days. They tend to move their prime rates by the same amount and in the same direction that the Bank of Canada moves the overnight lending rate.

How do banks use the prime rate?
Banks use the prime rate as a benchmark rate for a variety of financial products, including mortgages, personal loans, and lines of credit. The interest rate charged for these products is typically set at a margin above or below the prime rate. Most products will have a rate of Prime plus a margin but variable-rate mortgages for the best borrowers are usually priced at Prime minus a margin. For example, a bank might offer a variable-rate mortgage at a rate of prime minus 0.50% (equal to 3.95% today). As the Prime Rate moves up or down, the variable mortgage rate will move also, but the margin stays the same for the term of the mortgage.
How are variable mortgage rates set relative to the prime rate?
Variable rate mortgages are directly tied to the prime rate. When the prime rate goes up, so does the interest rate on a variable rate mortgage. Conversely, when the prime rate goes down, so does the interest rate on a variable rate mortgage. This means that borrowers with variable rate mortgages are exposed to interest rate risk, as the cost of their mortgage will increase if the prime rate increases.
The margin relative to the prime rate depends on market conditions, the risk profile of the borrower and the costs of lending. When market conditions are positive, the margin for the best borrowers can be more than 1.00%. When market conditions are weaker, that margin can be as small as 0.25% to 0.50%.
The prime rate is usually the same for all banks. They will use their prime rate for pricing variable rate mortgages and the competitive difference in rate between the banks is the margin below the prime rate that they offer. However, there is one bank that does things differently. TD Bank uses a prime rate for mortgage lending that is equal to their prime rate plus 0.15%. They have been doing this since 2016. Borrowers should note this since TD needs to offer a larger margin discount to their prime rate to get you to the same rate being offered by other lenders.
| Rate | Target Overnight Rate | Prime Rate | Variable Mortgage Rates |
| Who Decides | Bank of Canada | Banks | Banks & other lenders |
| Current Rate | 2.25% | 4.45% | Between 3.60% and 5.2% |
What is the historic margin between variable mortgage rates and the Prime Rate?
The historic margin between variable mortgage rates and the prime rate has varied over time. In general, the margin tends to be a discount ranging between 0.25% and 1.5%, depending on market conditions and the risk profile of the borrower. During times of economic uncertainty or when credit conditions are tight, banks may offer less of a discount margin to account for increased risk.
For those of you that are looking to get a Heloc, you should note that the rate for a Heloc will be higher than for a variable-rate mortgage. Helocs carry an interest rate that is usually prime plus a margin. This margin can range between 0.50% and 3.0% at the banks.
Can anyone predict where the prime rate will go in the future?
Predicting where the prime rate will go in the future is difficult. It is influenced by a wide range of factors and, as we saw in 2022, can be subject to sudden changes. Some economists and analysts use models to forecast the future direction of interest rates, but these projections are often imprecise and subject to error. Ultimately, the direction of the prime rate will depend on a variety of economic factors that influence the rate setting policy of the Bank of Canada, including inflation, economic growth, and the supply and demand for credit.
Most Recent Bank of Canada Rate News
The Bank of Canada announced on October 29th that it has reduced its overnight policy rate by 25 basis points to 2.25%. This decision follows shortly after a similar cut last month and signals the Bank’s cautious approach in light of ongoing trade uncertainty with the United States. The Bank also suggested the easing cycle may be over.
Although the market is not anticipating additional rate cuts this year, it’s important to put the current environment in context. We have emerged from an extended cycle of rate reductions, and today’s rates are not only historically aligned but also at levels found in a healthy economy. This renewed affordability presents a timely opportunity for borrowers to re-evaluate their mortgage options and potentially benefit from the favorable rate landscape.
With this change, both the prime rate and variable mortgage rates will decrease by 0.25% by tomorrow. You will see the prime rate at major banks lowered to 4.45%. Insured variable mortgage rates are now firmly below 4% as are many uninsured variable mortgage rates, depending on the lender. Insured variable rates as low as 3.54% will be available in some Provinces. For Canadians with variable-rate mortgages, this means a reduction in borrowing costs and delivers relief for household budgets.
Bond yields have varied throughout the year and are down by over 0.40% since the summer. However, this only has them back to where they were in the spring. Since fixed mortgage rates are tied to bond yields, and not the Bank of Canada rate, there is no relief in sight for fixed mortgage rates.
Bank of Canada Governor, Tiff Macklem, indicated that this level of rates might be sufficient to hold inflation near their 2% target, while also supporting the economy. The Bank stated that "GDP growth is expected to be weak in the second half of the year" and they do not project a pick-up in GDP growth in 2026. They also stated "The Bank expects inflationary pressures to ease in the months ahead and CPI inflation to remain near 2% over the projection horizon."
The importance of a resolution to our ongoing trade dispute with the US couldn't be more clear. Our central bank is focused on it and it affects significant policy decisions. This is made clear when the Bank states "The Canadian economy faces a difficult transition. The structural damage caused by the trade conflict reduces the capacity of the economy and adds costs. This limits the role that monetary policy can play to boost demand while maintaining low inflation. The Bank is focused on ensuring that Canadians continue to have confidence in price stability through this period of global upheaval."
In recent years average Canadians have thought about and discussed what the Bank of Canada is doing more than we can ever recall. Hopefully now that rates are back to historically normal and healthy levels, this focus on the Bank will diminish. If you attended a sporting event and all the talk was about the referees, then is wasn't a good event. We hope going forward that we can talk less about the referee in our market (the Bank of Canada) and more about people, products, opportunities and solutions. These are the conversations we expect in a healthy market.

Conclusion
The Canadian bank prime rate plays an important role in the country's financial system, serving as a benchmark rate for a variety of financial products. While the Bank of Canada does not directly set the prime rate, it does have an indirect influence on it through its monetary policy. Banks use the prime rate as a basis for setting interest rates on loans and lines of credit, and borrowers with these variable-rate products, such as variable-rate mortgages, are exposed to interest rate risk. While predicting the future direction of the prime rate is difficult, understanding how it is determined and how it is used by banks and borrowers can help individuals make informed financial decisions.
If you have a variable rate mortgage you need to be aware that rates may increase. Current market expectations are that the Bank of Canada may be done cutting rates. While this reflects current market consensus, be careful not to put too much weight on these predictions. They have been wrong in the recent past and the tariff noise makes predicting the future even more difficult. If you are risk-averse, manage your own affairs without trying to guess where rates are going. Variable-rate mortgages contain risk and are not for everyone. If you are certain in your belief that rates are coming down then a variable-rate mortgage might make sense if you can tolerate the risk financially.
If you are in the market currently for a mortgage, a fixed mortgage rate might be the best solution. Perhaps even a short-term fixed-rate mortgage. With no exposure to interest rate risk during the term of the mortgage, a fixed-rate mortgage is the conservative choice for the majority of us that have a low risk tolerance.

When the bank of Canada increases or decreases their overnight target borrowing rate, the banks will usually change their prime rate by the same amount within a couple days.
The prime rate does not directly affect fixed mortgage rates. It does affect variable mortgage rates. Most mortgage lenders set their variable mortgage rates at a margin versus the prime rate. This can be either a premium or discount to the prime rate. For example, for a prime, closed variable rate mortgage you might see the rate quoted at prime minus x%. For a heloc you may see a rate of prime plus x%.
All the major banks set their own prime rate. They tend to be the same over time among all the banks. However, for pricing mortgages, TD Bank has a prime rate 0.15% higher than the other banks. Non-bank mortgage lenders will price their variable-rate mortgages using the prime rate from their chosen bank.
Also referred to as the Bank of Canada’s policy rate, this is the benchmark cost of borrowing set by the Bank of Canada. It is the rate at which Canada’s banks can borrow money from each other or from the Bank of Canada on an overnight basis. The BoC updates the rate periodically throughout the year. This rate is the main tool used by the BoC to set monetary policy. They adjust the rate to regulate the cost of borrowing and demand for investment and this can be used to control inflation and economic activity.
