I have not been able to. I got the below message. Is it the same for you? I got this when trying to create my tracker account for citizenship. Any other website to try ??Were you able to create it today?
“ Incorrect or invalid information. Review and make sure it matches the information submitted on the Use of a Representative [IMM 5476] form or the Authority to Release Personal Information to a Designated Individual [IMM 5475] form. If you can't create an account, it may be because your client's application is not in our system yet.“
