The TD prime rate is the lending interest rate that TD Bank in Canada uses as a baseline for setting interest rates on variable loans, lines of credit, and mortgages. As of September 18, 2025, TD Bank's prime rate is 4.70%. TD also uniquely posts a separate prime rate specifically for mortgages, which is typically about 0.15% higher than the main prime rate, currently around 7.10% or slightly varying depending on the source and timing.

This prime rate fluctuates in response to the Bank of Canada’s policy interest rate changes and directly affects variable loan interest rates; when the prime rate changes, the interest rates on these loans usually change as well. TD’s mortgage prime rate is commonly set slightly above the general prime rate, reflecting the cost specifics of mortgage lending.

In summary, the TD prime rate is a key benchmark interest rate used by TD Bank to determine the variable interest rates charged on many credit products, and it currently stands at 4.70% as of mid-September 2025. The mortgage prime rate is separately posted and usually a bit higher than this standard prime rate.
