Oh I just did this (I'm almost finished, just got my social insurance left). It's such a pain in the butt lol. I recommend making a list, if you haven't already, of all the things that need changing. Given I also changed my gender on everything while I was at it, but it's taken a while o_O But it's so much fun, i'm happy for you mate! I love telling people my name and having to sign for stuff.
