It is this address!
I haven't registered to the online tax thing yet... I will call them tonight after work so they can send me my login number.
My big question is: in 2012 I was employed and my boss paid all the taxes to Revenue Canada himself. In 2013 and 2014 I had the same job, same contract, same visa but my boss decided that he no longer wanted to pay the taxes himself, so I had to pay them (which I did, of course. I am still paying for 2014 though). This means that I don't have a T4 for 2013 and 2014... I can probably give them the notice of assessments but how can I do regarding my T4? Not all the employers give them I suppose...?
