Securing the lowest mortgage interest rate in Ontario can save you tens of thousands of dollars over the life of your loan.
As of January 2026, the best 5-year fixed mortgage rate in Ontario is 3.84%, while the best 5-year variable rate is 3.45%.
With the Bank of Canada holding its overnight rate at 2.25%, understanding how to position yourself for the best possible rate is essential for Ontario homebuyers and those looking to refinance.
Understanding the Current Ontario Mortgage Market
Ontario’s mortgage market is highly competitive, with Toronto serving as Canada’s financial capital. The province accounted for 52% of all mortgages in Canada as of 2023, creating a dynamic lending environment.
Major banks, credit unions, mortgage brokers, and alternative lenders all compete for your business, which works in your favor when shopping for rates.
The mortgage rate landscape has improved significantly from its peak. The Bank of Canada lowered the benchmark rate from 5% to its current 2.25%, keeping the prime rate steady at 4.45%.
While rates have fallen considerably, experts predict they will remain relatively stable through much of 2026, making this an opportune time to secure competitive rates.
1. Improve Your Credit Score
Your credit score is one of the most powerful tools for securing a low mortgage rate. Lenders view borrowers with higher credit scores as lower risk, which translates directly into better rates. The lowest mortgage rates typically go to borrowers with credit scores in the highest range.
Steps to boost your credit score:
- Pay all bills on time, as payment history heavily influences your score
- Keep credit card balances low relative to your limits
- Avoid opening new credit accounts before applying for a mortgage
- Dispute any errors on your credit report with Equifax or TransUnion
- Don’t close old credit accounts, as length of credit history matters
Start working on your credit score months before you plan to apply for a mortgage. Even small improvements can result in rate savings that add up to thousands of dollars over time.
2. Lower Your Debt-to-Income Ratio
Your debt-to-income (DTI) ratio directly impacts the interest rate lenders offer you. To get the lowest mortgage rate, aim for a DTI of 25% or less, though lenders may consider ratios up to 50%.
To calculate your DTI, divide your total monthly debt payments by your gross monthly income, then multiply by 100. For example, if you have $1,100 in monthly debt obligations and earn $5,000 per month, your DTI is 22%, which positions you well for competitive rates.
Ways to reduce your DTI:
- Pay down credit card balances aggressively
- Consolidate high-interest debt
- Avoid taking on new loans or financing before applying
- Consider increasing your income through side work or a raise
3. Make a Larger Down Payment
Making as much of a down payment as you comfortably can is a best practice for getting the lowest mortgage rate. A larger down payment reduces the lender’s risk and demonstrates your financial stability.
In Ontario, putting down at least 20% allows you to avoid mortgage default insurance (CMHC insurance), which adds to your costs.
Beyond that threshold, you may qualify for even better rates. For homes below $1 million, the required down payment is less than 20%, but going above this threshold can unlock better terms.
4. Shop Around and Compare Lenders
One of the biggest mistakes Ontario homebuyers make is accepting the first rate they’re offered. Getting at least three to five rate quotes gives you real leverage when choosing a lender.
Where to shop for rates in Ontario:
- Big 5 Banks (RBC, TD, Scotiabank, BMO, CIBC)
- Credit unions like Meridian or DUCA
- Online lenders and fintech companies
- Mortgage brokers with access to multiple lenders
Don’t limit yourself to your current bank just for convenience. Banks may be more willing to negotiate with a mortgage broker who has sent them millions of dollars in mortgage business over the years, rather than an individual customer.
5. Consider Working with a Mortgage Broker
Mortgage brokers represented 43% of total mortgage originations in 2023, and for good reason. Brokers can access multiple lenders and often secure rates that individual borrowers cannot obtain on their own.
Benefits of using a mortgage broker:
- Access to multiple lenders, including smaller institutions with competitive rates
- Professional negotiation on your behalf
- Knowledge of which lenders best suit your specific situation
- Often no cost to you, as they’re paid by the lender
- Can find solutions for borrowers with unique circumstances or less-than-perfect credit
Mortgage brokers acquire high quantities of mortgage products and can pass volume discounts directly on to you. They can also access exclusive deals not available on the open market.
6. Choose the Right Mortgage Term and Type
The type and term of your mortgage significantly affect your rate. As of January 2026, the best high-ratio 5-year fixed mortgage rate in Ontario is 3.84%, while the best 5-year variable rate is 3.45%.
Considerations when selecting your mortgage:
- Shorter terms (like 15 years) typically offer lower rates than longer terms but higher monthly payments
- Variable rates are currently lower than fixed rates, but carry the risk of future increases
- Consider your risk tolerance and financial stability when choosing between fixed and variable
- Match your term length to how long you plan to stay in the home
Given current market conditions, many experts recommend a 5-year fixed near or under 4% as balancing stability and cost.
7. Get Pre-Approved and Lock in Your Rate
Getting pre-approved for a mortgage serves multiple purposes. It shows sellers you’re a serious buyer, helps you understand your budget, and allows you to lock in a rate for typically 90-120 days.
You can lock in your rate for up to 120 days with mortgage pre-approval. This protects you if rates rise while you’re house hunting. If rates fall during your hold period, many lenders will honor the lower rate.
8. Negotiate and Don’t Accept Posted Rates
Posted rates are rarely the best rates available. Some mortgage brokers in Ontario are offering fixed rates well under 3.7%, though they’re well over 4% at most banks. This gap illustrates the importance of negotiation.
Negotiation strategies:
- Use competing offers as leverage
- Ask about rate discounts for consolidating banking services
- Inquire about loyalty discounts if you’re an existing customer
- Don’t be afraid to ask lenders to match or beat competitors’ rates
- Consider the total cost, including fees, not just the interest rate
9. Understand the Impact of Even Small Rate Differences
With a fixed mortgage rate of 4% for five years on an $800,000 mortgage, the total interest paid would be $148,921, while at 5% it would be $187,230. That’s a difference of over $38,000 for just one percentage point.
Even smaller differences matter significantly. A 0.2% rate difference on the same mortgage amounts to thousands in additional interest over the term. This underscores why putting in the effort to secure the lowest possible rate is so financially impactful.
Timing Your Mortgage Application
While you can’t perfectly time the market, understanding rate trends helps. The Bank of Canada rate of 2.25% is currently expected to hold for a few months, perhaps through to Q3 2026.
Rather than trying to time rate movements, focus on controllable factors like your credit score and down payment savings.
Fixed mortgage rates follow bond yields rather than the Bank of Canada rate directly. Bond yields remain around the 3% range, and fixed rates are unlikely to decrease in the near term.
Special Considerations for Ontario Homebuyers
Land Transfer Tax: In Ontario, you’ll pay land transfer tax based on your home’s value, with rates topping out at 2.5% for values over $2 million. Toronto homebuyers pay an additional municipal land transfer tax. Factor these costs into your overall budget planning.
Market Conditions: Ontario home sales totalled 12,087 in November 2025, down 13.1% compared to November 2024, with the average home price declining 5.8% to $819,356. This buyer-friendly market gives you more negotiating power on both home prices and mortgage terms.
Final Recommendations
Securing the lowest mortgage rate in Ontario requires preparation, research, and persistence. Start by strengthening your financial profile through improved credit and reduced debt. Shop extensively among banks, credit unions, and brokers. Don’t hesitate to negotiate aggressively and leverage competing offers.
Remember that the lowest advertised rate isn’t always the best deal once you factor in fees, penalties, and features.
Consider the total cost of the mortgage and ensure the product aligns with your financial goals and circumstances.
By following these strategies and staying informed about market conditions, Ontario homebuyers can position themselves to secure the most competitive mortgage rates available, potentially saving tens of thousands of dollars over the life of their mortgage.
