How Often Do Mortgage Rates Change in Canada?
Mortgage rates in Canada do not follow a fixed schedule. Rates can change at any time, sometimes daily, depending on whether you are looking at a fixed or variable rate. For borrowers, that unpredictability can directly impact affordability, qualification, and long-term borrowing costs.
Whether you are shopping for your first home, approaching a mortgage renewal, or considering a refinance, the frequency of rate changes directly affects your mortgage strategy. This guide breaks down how often fixed and variable rates change in Canada and how to position yourself, no matter which way rates travel next.
Key Takeaways
- Fixed mortgage rates can change at any time when bond yields move significantly enough for lenders to reprice.
- Variable mortgage rates change only when the Bank of Canada adjusts its policy rate.
- Lenders can adjust their spread at any time due to funding costs, competition, or risk conditions.

How Often Fixed Mortgage Rates Change
Fixed mortgage rates in Canada are primarily tied to Government of Canada bond yields of corresponding maturities. When bond yields rise, lenders face higher funding costs, which are passed along to borrowers as higher fixed rates. When yields fall, fixed rates tend to follow, though not always as quickly. Lenders tend to react quickly when yields climb because this impacts their margins. When yields decline, lenders often wait to see whether the decline is stable before lowering rates.
Bond yields themselves change constantly over the trading day based on what is happening in the economy and financial markets. Inflation expectations, global economic uncertainty, U.S. Treasury movements, employment data, and investor sentiment all influence daily bond yield movements.
In theory, that means fixed-rate pricing could technically change every business day. In practice, most lenders wait to update their fixed rates when bond yields move enough to justify a new rate. Small daily movements or minor fluctuations are typically absorbed within the spread a lender already has priced in.
How Often Variable Mortgage Rates Change
Variable mortgage rates in Canada are tied to a lender’s prime rate, which moves in response to the Bank of Canada policy rate. The BoC makes eight scheduled rate announcements each year, spaced roughly six weeks apart. During each scheduled announcement, the Bank will decide whether to raise, lower, or hold the overnight rate. That means variable rates could change up to eight times annually, though not every announcement results in a change in the policy rate.
If the BoC holds rates, a lender’s prime rate will remain the same, and so too will variable rates. When the BoC decides to raise or lower its policy rate, lenders adjust their prime rate by the same amount within a day or two, affecting variable rates. During periods of stability, variable rates may remain unchanged for several months. During active tightening or easing cycles, rates could change approximately every six weeks.
However, outside the regular schedule, the BoC has the authority in emergencies to act beyond the scheduled announcement dates. They can act anytime there is an economic risk that requires immediate monetary policy intervention. Emergency decisions like these are rare. The most recent example came during the pandemic, when the sudden economic shutdown prompted the BoC to deliver multiple unscheduled rate cuts within weeks, which had an immediate impact on lenders’ prime rates and variable interest rates.

Lenders Can Adjust Their Rates Anytime
Beyond bond yields and the Bank of Canada’s policy rate decisions, lenders can adjust their own rates at any time by widening or narrowing their spreads. The spread is the margin a lender adds to its benchmark funding costs. Even when bond yields remain stable and the BoC is in a holding pattern, the advertised rate can still change if the lender adjusts its spread.
Several factors drive these adjustments. Changes in funding costs, whether through securitization markets or deposit pricing, can push lenders to reprice. Competitive pressure also plays a role, especially when lenders are trying to win market share or respond to aggressive pricing from others. Internal risk tolerance and lending targets can also drive changes in a lender’s spread. Demand for mortgages can also influence pricing, particularly during peak buying seasons or slowdowns.
These spread adjustments affect any new mortgage, renewal, or refinance application. Borrowers already locked into a fixed or variable mortgage are not impacted until they are up for renewal or choose to refinance.
How to Protect Yourself from Rate Volatility
Rate changes are inevitable, especially for fixed rates, where bond markets drive pricing. Getting pre-approved for a mortgage is the most straightforward place to start. A pre-approval typically includes a rate hold, which guarantees your rate even if rates rise while you shop. Depending on the lender, you can typically hold rates for 90-120 days.
Working with a mortgage expert also matters more than most realize. Different lenders price risk, funding, and their margins differently, even under the same market conditions. Having access to multiple lenders increases your chances of finding a better rate or product fit at any given moment, rather than being limited to a single offer.
For homeowners approaching renewal, starting early is critical. You can often begin the renewal process 120 days before your current term expires, giving you time to compare options, lock in a rate, and avoid feeling rushed. Comparing renewal rates across lenders, rather than simply signing your bank’s first offer, consistently saves borrowers money.
Frequently Asked Questions (FAQ) About How Often Mortgage Rates Change
How often does the Bank of Canada change the policy rate?
The Bank of Canada makes eight scheduled announcements per year, spaced roughly six weeks apart. Not every announcement results in a change to the policy rate. The central bank evaluates inflation, employment, GDP, and global conditions before deciding whether to raise, lower, or hold the policy rate.
Can my fixed mortgage rate change during my term?
Once you sign a fixed-rate mortgage contract, your interest rate remains the same for the entire term you’ve selected. Market rates may rise or fall during this time, but your payment and rate are locked in. The only way your rate can change before the term ends is if you break your mortgage early.
Do all lenders change their mortgage rates at the same time?
Lenders do not change their rates simultaneously. Each institution sets its own pricing based on its funding costs, competitive strategy, and business targets. After a BoC announcement, most lenders will adjust their prime rate within one to two business days, but promotional rates and discounts vary based on their spread. Changes to fixed rates depend on when each lender responds to bond market movements, which may not occur on the same day as other lenders.
Can a lender change my rate after pre-approval?
In most cases, a mortgage pre-approval comes with a rate hold that protects your rate for a set period. During that time, the lender agrees to honour the locked-in rate even if market rates rise before your purchase closes. However, a pre-approval is still conditional. The lender can revisit or change the offer if key parts of your application change. This can include a lower credit score, new debts, employment changes, reduced income, a change in property type, or a higher loan amount than originally approved. If interest rates rise significantly, or closing is delayed, and the rate hold expires before closing, the lender may also offer a higher rate based on current market pricing.
Final Thoughts
The short answer to how often mortgage rates change in Canada is: it depends. Fixed rates are tied to bond yields that fluctuate every business day. However, that doesn’t mean that fixed rates will change daily. Variable rates move in line with the Bank of Canada’s schedule, up to eight times per year. And lenders can widen or narrow their spreads whenever competitive, funding, or risk conditions shift enough.
For borrowers, the practical takeaway is that waiting for the perfect rate is a losing strategy. Rates will always change. What matters is whether you have the tools in place to act when the right opportunity appears. That means having a pre-approval with a rate hold, access to multiple lenders through a mortgage expert, and enough lead time to compare your options.
