September 2025 Mortgage Renewal Strategies: Locking in or Rolling the Dice on Rates?

For thousands of Canadian homeowners, September 2025 marks a pivotal moment. With roughly 1.2 million mortgages up for renewal this year, many are faced with a crucial decision: should you lock in a fixed rate for the security it offers, or "roll the dice" on a variable rate in the hope of further cuts?


The rate environment today is dramatically different from five years ago. This blog post will break down the current landscape, weigh the pros and cons of fixed and variable mortgages, and provide practical strategies to help you make the best choice for your financial future.

The Current Rate Environment: What You Need to Know

The Bank of Canada’s recent decisions are at the heart of the matter. Following a series of rate cuts totalling 225 basis points between mid-2024 and early 2025, the BoC has held its target for the overnight rate steady at 2.75% since March. The next announcement is scheduled for September 17, 2025.

  • Fixed Rates: These are primarily influenced by government bond yields, particularly the 5-year Canada bond yield. While the BoC’s holds have created some stability, the bond market remains sensitive to economic data and global events. As of early September 2025, the best 5-year, insured fixed mortgage rates hover around 4.09%.
  • Variable Rates: These are directly tied to your lender’s prime rate, which moves in lockstep with the BoC's overnight rate. With the BoC holding its policy rate at 2.75%, the prime rate has remained stable at 4.95%. This means that variable-rate payments have not changed in recent months, offering a period of calm for those who chose this option.


Fixed vs. Variable: A Breakdown of the Pros and Cons

The choice between a fixed and variable rate at renewal is personal, with no single "right" answer. Your decision should align with your financial situation and risk tolerance.

Mortgage Type Pros Cons Who It's For
Fixed-Rate Stability & Peace of Mind: Your payment and interest rate are locked in for the term, providing predictability for your household budget. Missed Opportunity: You could miss out on savings if rates fall further over your term. Homeowners who prioritize budget certainty and have a low tolerance for risk.
Variable-Rate Potential for Savings: If the Bank of Canada cuts rates further, your payments will decrease, saving you money. Uncertainty: While a rate hike seems unlikely, payments could increase if unexpected economic factors force the BoC’s hand. Homeowners with a healthy emergency fund who can absorb payment fluctuations and are comfortable with some risk.

The Forecast: What Experts Are Predicting

The consensus among economists is that the BoC's rate-hike cycle is firmly in the rearview mirror. However, there's a split on the timing and pace of future rate cuts.

  • Most economists expect the BoC to begin a new round of rate cuts in late 2025, with many forecasting the policy rate to drop to as low as 2.25% by year-end.
  • Some analysts are more cautious, believing the BoC will hold the rate for the remainder of 2025 to monitor inflation and economic growth, with cuts likely to begin in 2026.

The long-term outlook is for a gradual decline in interest rates, but it's important to remember that these are just forecasts. Unexpected events, such as new trade tariffs or a shift in the global economy, could alter this trajectory.

Strategies for a Successful Renewal

Whether you choose a fixed or variable rate, the renewal process itself is an opportunity to save thousands of dollars. Don't simply sign the renewal offer your bank sends you.

  1. Start Early: Begin the process at least 4-6 months before your renewal date. This gives you ample time to shop around and get pre-approved for a rate with another lender.
  2. Don't Auto-Renew: Your current bank's renewal offer is rarely their best offer. Use a competitor's mortgage offer as leverage to negotiate a better rate.
  3. Negotiate: Your credit history, equity in your home, and financial health all give you leverage. Be prepared to ask for a discount, as lenders would rather keep your business than lose it.
  4. Consider All Options: Think beyond the term and rate. Can you change your amortization period to lower your monthly payment? Are the prepayment privileges sufficient for your needs? A mortgage professional can help you explore all of these options.

Conclusion: Making the Right Choice for You

Renewing your mortgage is one of the most significant financial decisions you'll make as a homeowner. Recent interest rate volatility, present stable rates and potential for future cuts tell us that the rate environment can change. 

The best strategy is to be proactive and informed. While the choice between fixed and variable is essential, the most critical step is to shop around and negotiate for the best deal possible.

What are Canadian mortgage rates going to do in 2026? We expect mortgage rates to remain fairly stable through 2026. We think that the Bank of Canada will hold rates steady for much of the year, though some analysts are calling for hikes in the latter half of the year. Bond yields are also expected to remain stable, meaning that fixed mortgage rate should not move much. Predictions are difficult and the markets are sending mixed signals right now. Read on to find out what this might all mean? 2026 Mortgage Rate Prediction Mortgage rates should remain within a close range near current rates for most of 2026. Variable mortgage rates will follow the Bank of Canada rates, which are expected to remain flat for the first half of the year. Bond yields could fluctuate with economic news and fixed mortgage rates will follow but are likely to remain within the high-3% to mid-4% range, absent any significant economic surprises. Variable Mortgage Rates in 2026 We expect variable mortgage rates to remain mostly unchanged in 2026, potentially increasing by 0.25% to 0.50% if the Bank of Canada hikes toward year-end. The one huge caveat to this is that if the ongoing trade discussions with the US go poorly, weakening Canada’s economy, there may be an incentive for the Bank of Canada to make some cuts, as long as inflation remains under control. We do not hope for this poor economic news so prefer to not predict it to be likely. Variable mortgage rates are now below fixed mortgage rates and should remain there for the time being. We anticipate five-year variable mortgage rates for the best borrowers to range from 3.4% to 4% throughout the year, depending on any policy shifts. Fixed Mortgage Rates in 2026 We do not expect much change in fixed mortgage rates in 2026, but there is a risk that fixed rates could increase. Bond yields have already priced in limited Bank of Canada cuts and have been stable lately. The recent stability in the US 10-year Treasury yield around 4.2% suggests the bond market is cautious about further cuts. In Canada, bond yields are exactly where they were one year ago, with the five-year Canada bond at 2.88% in late January 2026. We must pay heed to those signals since fixed mortgage rates depend on the bond market. We anticipate five-year fixed mortgage rates to range between 3.7% and 4.3% for most of the year. We rely on market inputs to generate our own expectations for mortgage rates in 2026. Those key inputs include: The Bank of Canada has indicated the current overnight rate of 2.25% is "about right" to keep inflation near 2%, but stands ready to respond if needed; Economists are forecasting moderate Canadian economic growth, which may not require further stimulus; The US Federal Reserve is expected to cut rates gradually in 2026, potentially two to three times, but with uncertainty from trade policies; The US 10-year Treasury yield has hovered around 4.2% in early January 2026; Canadian 5-year bond yields are around 2.88% in late January 2026, flat to a year ago and showing no signs of a downward trend; and Excessive government borrowing puts pressure on bond yields to rise to entice investors to buy the large volume of government debt There are many risks that are not priced in yet that could materialize. Economic weakness or tariff impacts could prompt more rate cuts and lower bond yields. The trade agreement between Canada, Mexico and the US expires this year and needs to be renegotiated. Economic strength or resurgent inflation could lead to hikes and higher rates. There are also political and geopolitical risks that are making headlines that are not in our area of expertise. They are difficult to predict but could significantly impact our interest rate markets in 2026, a year currently marked by uncertainty. What Happened to Mortgage Rates in 2025? In 2025, Canadian fixed mortgage rates remained relatively stable, declining by a modest 0.20% through the year. Canadian variable-mortgage rates declined by 1.0%, in lockstep with the Bank of Canada reducing their target rate by the same amount in 2025. The Canadian market entered 2025 with expectations for gradual Bank of Canada cuts, which materialized with reductions totaling 1.00% from January through October. The first cuts came in January and March (0.25% each), followed by holds through summer, then additional 0.25% cuts in September and October. The end result was a reduction in the overnight rate to 2.25% where it remains as we embark on a new year in 2026. The Bank of Canada rate cuts in 2025 had the expected direct impact on variable mortgage rates, which dropped by the same amount. Fixed rates are ‘forward-looking’, so they moved in anticipation but stabilized as cuts slowed. As the chart shows, fixed mortgage rates have levelled off over the past year.
