Your OWP gives you authorization to get a SIN
Your SIN gives you authorization to work...
Go to Service Canada and get your SIN, it takes no time at all. Make sure you also bring something with your current address on it! Bring everything you can think of...they can be real sticklers down there LOL
Your temp tax number means nothing...your new SIN will replace that when you go to do your taxes in February
One thing we learned throughout this whole process, is go into all these offices with more information then you need, or you end up waiting for nothing...some people can be helpful, some just want the paycheck!
