Filing

The CRA generally processes returns submitted through NETFILE within two weeks. But if you are getting your NOA through the mail, it may take longer. After you get it, you can sign up for CRA MyAccount if you'd like. 

And yes, you should get an email with your NETFILE confirmation number, though it will also stay with your return so you can go back and see it there too. Check your spam/junk folder as the email may have gone there.
