OK, I added one thing for those of us who were not born here. It takes FOREVER to get a citizenship card, and if you don't change your SIN first, you're hooped.
I sent my change in to citizenship in August. Got a letter in September saying it would take 5-7 months. I just got a letter last week that said it would take "longer than expected". So I'm trapped in the country for god knows how long.
