Hi everyone, I renewed my work permit but silly me I forgot to renew my SIN card since that card has an expiry date corresponding to my old work permit. So currently my SIN card has expired for more than 2 months. HR at my company didn't ask me about a new SIN card when I gave her copy of my new work permit so I completely forgot I have to renew my SIN card. Now since it's already expired I'm not sure if I can renew or I have to apply for a new SIN card. If I do need to apply for a new SIN #, how will that affect me when I file for tax - just renew my information with Revenue Canada??? Please help....thanks a lot!!!!
