When you spend Canadian dollars at a business owned by a Canadian, you're sending that owner and the Canadian government your money, in exchange for their goods or services, normally at a surplus of value for them. You are 'helping' them; you are 'investing' in the Canadian economy. You are justifying the existence of their business and the jobs of the people who work there.
Especially insofar as you're making this choice versus American options, you are putting money into the hands of Canadians rather than Americans. This is the underlying concept behind boycotts and voting with your dollars or feet.
