I was in Canada a while ago, with a tourist visa. I opened a bank account, and had a credit score.
Now, I became a PR. Do I transfer my previous credit score as a tourist to my new credit score as a PR? If so, how?
Your credit score is not tied to your residency status and should not be affected. Don't worry about the change in your SIN #, the system is automated as far as I know and tracks many other things including your name, addresses, bank accounts, credit usage, etc...you should have no issues.
