I already sent my files by mail, they already got them, what´s next step? just wait? thx!

Yes, you just wait. The CRA will contact you (usually by mail) if they need to.

Thank you! But what about my tax return?

If you mean your refund, you just have to wait. The CRA will process your return, send you your Notice of Assessment, and then send you your refund. If you don't have direct deposit set up, then they will send you a check by mail.

Thank you! I really appreciate it!
