Generally the CRA will only email a notice that there is a new message waiting for you on their site; you have to log in to their site to access the message. As far as security practices go, I won't complain about that.

Yeah, thats why I had email in quotes. Could have been more clear I guess. Still a problem that you need to accept their TOS to see if they decided you owe money.
