Student Exchange Programs

I’m from Mexico and probably will make a student exchange to Canada in two years and I’d like to learn some more about prices and costs. For example, rent, electricity, gas, transports and mostly food as you can see. It would be nice to know the lowest amount of money that a person could earn in a formal job because, who knows? I could need a job there (I hope it won’t happend). I will probably go to Montreal and I know that expenses are more in amount and more expensive so if you can tell me about costs I will thank you very much.

Thank you
Ps: Is also important to know more about the Canadian and Canadian-french cuisine, good colleges in Montreal (I am studying communication) and the opinion of Canadians about Mexican people.
