Used car loan interest rates in Ontario currently range from about 5% to 29%, depending on your credit score, income, and the specifics of the vehicle and loan. That's a wide range, so understanding how interest rates work — and what drives them — helps you make smarter financing decisions.
APR vs. Interest Rate: What's the Difference?
You'll see two numbers when comparing loans: the interest rate and the APR (Annual Percentage Rate). The interest rate is the cost of borrowing the principal. The APR includes the interest rate plus any mandatory fees (like administration fees or loan processing charges), giving you the true cost of borrowing. In Canada, lenders are required under the Cost of Borrowing Disclosure rules to show you the APR, so always compare loans using APR — not just the advertised rate. For most auto loans, the interest rate and APR are very close, but check for any added fees that might widen the gap.
Fixed vs. Variable Rates
The vast majority of used car loans in Ontario are fixed rate, meaning your interest rate stays the same for the entire loan term. Your monthly payment never changes, which makes budgeting straightforward.
Variable rate auto loans are rare in Canada. You might occasionally see them from credit unions or alternative lenders. With a variable rate, your interest can fluctuate based on the Bank of Canada's prime rate. This adds uncertainty to your monthly payment. For most buyers, especially those rebuilding credit, a fixed rate is the safer and more common choice.
How Your Credit Score Maps to Rate Ranges
In Canada, credit scores range from 300 to 900. Here's how that translates to used car loan rates:
- 750–900 (Excellent): 5% – 7%. You qualify for prime rates from major banks. Multiple lenders will compete for your business.
- 680–749 (Good): 7% – 10%. Still strong. You'll qualify at most lenders, though rates are slightly higher than prime.
- 600–679 (Fair): 10% – 15%. You may not qualify at every bank, but alternative lenders and some credit unions will approve you at these rates.
- 500–599 (Poor): 15% – 22%. You're in subprime territory. Specialized lenders who understand credit challenges will work with you.
- Below 500 (Credit Rebuild): 22% – 29%. These rates are higher, but they serve an important purpose — getting you into a vehicle and building payment history so you can refinance later at a lower rate.
Ontario-Specific Considerations
A few things are specific to auto loans in Ontario:
- Criminal interest rate cap: Under the Criminal Code of Canada, interest rates above 60% are considered criminal. For used car loans, you'll never see rates even close to this threshold from legitimate lenders.
- OMVIC protection: If you're buying from a registered dealer in Ontario, the Ontario Motor Vehicle Industry Council (OMVIC) provides consumer protections, including transparency on financing costs.
- HST on interest: Unlike the vehicle purchase price, you don't pay HST on interest charges for your auto loan.
- Credit bureaus: Ontario lenders report to both Equifax and TransUnion Canada. Making your auto loan payments on time builds your score with both agencies.
How Interest Affects Total Loan Cost
Here's a practical example. On a $15,000 used car loan over 60 months: at 7% you'll pay about $2,800 in total interest. At 15%, that jumps to about $6,200. At 25%, you're looking at roughly $11,000 in interest. That's why the rate matters so much — and why even a 2–3% improvement can save you thousands over the life of the loan.
