What happens if you don't agree to the TOS? Pretty sure that means you can't do your taxes, and you'd get in pretty hot water as a result. To me, that implies that the Canadian government is forcing you to agree to this TOS, which further reduces its legal defensibility.

You can file electronically without ever touching My Account. All you need is some info from your previous year's Notice of Assessment.

You can still mail in paper forms.

And the bad boys and girls can still hack CRA and if they defraud you using the data they stole is CRA still liable in spite of your paper-based filing?

You will have to prove a lot of "facts" to win that lawsuit. Especially since your social number(s), email, phone, whatsapp, etc are all public info already.

Recall a few years ago an uneducated hacker ("script kiddie") got part way into a CRA website and they took the whole website down for a week. (The attacker was caught, and prosecuted iirc.)

But they might still "email" any reassessment or whatever to your account if you setup paperless beforehand..

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.

[goosedragons]

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.

No, you don't have to have any electronic account with the CRA, you can file by paper, and they write you back by paper, and you can pay by cheque, or get your refund by cheque.
