Is Canada's Defence Policy over reliant on the United States in terms of funding initiaves and agreements for North American Defense?

I personally like this idea. We have to acknowledge that as much as we are our own entity there are a lot of outside influences, alliances e.t.c. that play into issues of defense. I like Nadeems idea of getting to the point and seeing whether or not people see a direct correlation between the US and Canada in defense policies.
