Refinancing Car Loan to Lower Interest Rate

I’m looking into refinancing my car loan to lower my interest rate and would appreciate some advice. I’ve had the loan for two years now, with a current interest rate of 8.49%.

Since I initially took out the loan, a few things have changed:

• I’ve transitioned from being on a work permit to becoming a permanent resident (PR).
• My credit score has improved significantly, going from the mid-700s to over 800.

Given these changes, how likely is it that I could secure a lower interest rate through refinancing? Any tips or personal experiences would be super helpful.

Thanks in advance!
