Can I file for both my sin numbers? I just got my PR last year in April, and I'm confused about how to go about it. I also have a T4A on my old sin number.

For clarification on what you should do in this case, you will need to contact the Canada Revenue Agency (CRA) as you will not be able to Netfile if you indicate two different SIN numbers. Please contact them at    1-800-959-8281.
