Canadian/mortgage/no job but poker

[GrindingIt]

How are people on here getting mortgages? In canada, even if you have a large down payment of over 50% they still want to verify your income through tax returns to see that you can pay your mortgage. I don't really understand if you make such a large payment that it could be a problem. Anyone can get fired or laid off for one thing.

Does anyone have experience with this or know where I should be looking? I tried a couple of mortgage brokers but they weren't much help yet.
