Will i qualify for a mortgage?

I have been at a new job but same profession with no gap for about 4 months making 60K. My fiancee is self employed making roughly half my income and has been self employed for 2 years. I know that to qualify for a mortgage in canada a self employed person needs to be working for atleast 3 years. Will the fact that I make considerably more than her help us out or basically is the mortgage qualification pending on me? I am not self employed, just my fiancee. Any useful answers are much appreciated!
