accounts:
It seems that there is no way to change your US account into a Canadian one(or some other country), but it does seem that you can create a new account with an email(I just used protonmail or my own email server) through your VPN. Also, try to do it on a desktop computer. You may also get warnings that you need to use the mobile app, but with enough tries of different ip addresses, it does seem to work eventually.
