You need biometrics requisition letter with bar codes to do biometrics. You can call Service Canada if you can do in the old letter.Hi everyone, I just received the biometrics instruction letter for my mother's PR. Apparently it was sent out last year but we never received it, so they have sent the same letter again dated November 2020. Can we still use this to do biometrics ? Or we need to have a new instruction letter generated ?
