New SIN...what happens to old SIN « on: March 25, 2017, 06:02:05 pm » Reply wi

Hello all,

I became a permanent resident yesterday ;D

Now that I'll be getting a new SIN, I was wondering about a few things.

1. In 2016, I had an open work permit and did some work for a few companies. When filing my taxes for 2016, will I file with my old SIN or my new? Since my SIN at the time was my temporary one.
2. Now that I'm a permanent resident, is my old temporary SIN immediately invalid? Or does the old SIN only become invalid after I receive my new one? I can't seem to find any info on this specific question online.

Thanks for reading!

Phone CRA and let them know you have 2 sin numbers. They will follow.
