So since it looks like there have been a lot of late December applications getting AOR's recently, it's possible that it could be our turn soon. So this is a good time to check your SPAM folders to ensure they're empty, and then set up a filter so that there's no chance of accidentally missing an email.
For gmail users, my method is to set a filter so that all emails from " *@cic.gc.ca " (without the quotes) have a red label applied, will never be sent to spam, and are marked as important. You can do this by going to settings, selecting the "Filters and blocked addresses" tab, and then clicking the "Create a new filter" link and filling out the form.
Other email programs will probably have a similar process.
Good luck everyone!
