Considering that money is a factor for me, but that I want to study an MBA in Canada in order to work there, what would be the best option? Would the extra cost of McGill's program pay off relatively soon, or is the quality of their program not that far off from a school like Concordia?

Which school has the best network of MBA alumni in the roles you are targeting? 

Yes, McGill seems to have a much better MBA alumni network when it comes to strategy and leadership, as far as I could tell. 

I guess attending a more affordable MBA can in a way be a false economy. I'll try my best to get some funding. 

Thanks Duncan!

Based on employment rates, salaries and how much the MBA will cost you, you can make a pretty useful and simple calculation to get a better idea.
