Let’s dive in!
What Affects Mortgage Rates in Ontario?
Both national and personal factors influence mortgage rates. While you can’t control economic trends, you can improve your financial profile and secure a better rate.
1. Bank of Canada Policies
The Bank of Canada (BoC) sets the overnight lending rate, which affects how banks determine mortgage rates. When the BoC raises rates to control inflation, mortgage rates tend to rise, while when the BoC lowers rates to stimulate the economy, they tend to drop.
📊 Current Trend (2025): Rates have fluctuated recently due to economic recovery efforts. Keeping an eye on BoC announcements can help you time your mortgage decision.
2. Inflation & Economic Trends
📈 Higher inflation = higher mortgage rates
📉 Lower inflation = lower mortgage rates
When inflation rises, lenders increase mortgage rates to protect their profits. A stable economy with controlled inflation usually leads to better borrowing conditions.
3. Your Personal Credit Score & Income
The rate you qualify for depends on your financial health. Lenders assess:
✔️ Credit Score: A score above 700 gets the best rates.
✔️ Debt-to-Income Ratio: The lower, the better.
✔️ Employment Stability: A steady job and income boost approval odds.
💡 Pro Tip: Check your credit report and fix any errors before applying for a mortgage. Even small improvements in your credit score can mean lower rates.
Fixed vs. Variable Mortgages – Which Is Right for You?
Choosing between fixed and variable mortgage rates depends on your risk tolerance and financial goals.
The Pros and Cons of Fixed-Rate Mortgages
✔️ Predictable payments – Your loan term's interest rate stays the same.
✔️ Peace of mind – No surprises, no rate increases.
❌ Higher starting rate – Fixed rates are often higher than variable rates.
❌ Less flexibility – If rates drop, you won’t benefit.
💡 Best for: Buyers who prefer stability and plan to stay in their home for the long term.
The Risks and Rewards of Variable-Rate Mortgages
✔️ Lower initial rates – Variable rates usually start lower than fixed rates.
✔️ Potential for savings – If rates stay low, you’ll save money.
❌ Uncertainty – Your rate can increase, raising your payments.
❌ More budgeting challenges – Requires financial flexibility.
💡 Best for: Buyers willing to take some risk in exchange for potential savings.
Hybrid Mortgages: The Best of Both Worlds?
Some lenders offer hybrid mortgages, where part of your loan is fixed, and part is variable.
✔️ Gives stability with a portion fixed.
✔️ Allows flexibility if rates drop.
❌ Can be complex – Requires careful planning.
💡 Best for: Buyers who want stability and flexibility in their mortgage.
How to Improve Your Mortgage Rate Before Buying
1. Pay Down Debt to Boost Your Credit Score
Lenders reward borrowers with low debt levels. Focus on:
✅ Paying off high-interest credit cards.
✅ Keeping credit utilization below 30%.
✅ Making all payments on time.
2. Increase Your Down Payment
The larger your down payment, the better your mortgage rate.
5% down (minimum in Canada) = higher rate.
20%+ down = lower rate + no mortgage insurance (CMHC fees).
💡 Pro Tip: Even increasing your down payment by a few percentage points can help you secure a better deal.
3. Shop Around with Multiple Lenders
Different banks and mortgage brokers offer different rates. Comparing multiple lenders ensures you get the best deal.
✔️ Traditional banks – Offer security but may not have the lowest rates.
✔️ Credit unions & alternative lenders – Often provide more flexibility.
✔️ Mortgage brokers – Can shop around for exclusive deals.
💡 Best Strategy: Get at least three mortgage quotes before committing.
Common Mortgage Mistakes to Avoid
🚫 Not Getting Pre-Approved
A mortgage pre-approval gives you a clear budget and strengthens your offer in a competitive market. Without it, you risk wasting time on homes you can’t afford.
🚫 Taking on Too Much Debt
A bigger mortgage isn’t always better. Overextending yourself can lead to financial stress if interest rates rise.
💡 Solution: Use the 30/30/3 Rule:
Mortgage payments shouldn’t exceed 30% of monthly income.
Total housing costs (taxes, utilities, etc.) shouldn’t exceed 30%.
Have 3 months of emergency savings before buying.
🚫 Not Reading the Fine Print on Mortgage Terms
🔎 Check for hidden fees (prepayment penalties, rate adjustments).
🔎 Understand payment flexibility (can you make extra payments?).
🔎 Know renewal terms – Will you get the same rate when renewing?
💡 Pro Tip: Always ask about the total cost of the mortgage over its full term.
