I just landed today actually. Picked up COPR and decided to just land and complete the process since my wives landlord needed my SIN # for the lease paperwork, can't get that without landing. I had to leave Canada and re-enter (or I suppose if you had it mailed elsewhere this wouldn't apply). Then told the agent I was landing, they brought me inside and asked me some questions, confirmed I hadn't been arrested, etc. and then gave me a form for goods to follow list (wasn't moving anything in today), some other paperwork for my car and sent me on my way. They didn't let me leave without giving me a little Canadian flag either
It was late so tomorrow I'm going to get my SIN, etc. Best of luck with your application and thanks to everyone for the help.
