I am Canadian and I was wondering if anyone could give me the name of a reputable Property Management Association in Canada...and more specifically, in Ontario?

You will still need anywhere from 20-30% to get into any Canadian deal if you do not have the down payment nobody will give you anything.. 

They will want to know about your other projects and your global cash flow.In my 27 years of commercial originating and underwriting, I have seen many cases where borrowers were individually so strapped with personal or other debt they had to take a draw from the subject loan resulting in the cash flow tanking.

The do look at previous income but it's not a totally "global" approach that most banks take.

Globally all income will likely need to be 1.4x all of your debt payments.
