Got CoPR for me and my spouse on 14th Apr. Sent photos on 26th Apr through untracked Canada Post mail, should I send it again with tracking as I can see few people are reposting missing mails from Canada Post. My second question is, I sent two separate mails for me and my spouse is that the wrong way do it? Should I have sent them in one package? And my final question is, how do I update my address? I don't think there is an option to do it online, should I use webform or call IRCC ? Please suggest, so that I can correct if anything is wrong in the above process.
