I phoned Service Canada to change my address. After being told they have an “unusually high call volume”, they directed me to their website. The recording specifically said I could change my address there. I went through about 15 hoops to sign up for an epass account (four security questions, the usual user id and password, three different agreements to privacy statements and a bunch of personal questions), only to be told that I wasn’t eligible to change my address online. It listed a bunch of reasons, none of which applied to me.
So I phoned back and was told to try again later, as their call volume was too high. Nice.
