Without essential funding from Canada, the US will need to develop a cheaper plan.

Rather than outright shoot missiles out of the air, it will be cheaper to "trick" the missile into falling short---somewhere in Canada.

That way the US and Canada can both cut back funding.

Without essential funding from Canada, Realistically how much money could Canada even provide if it wanted to? Very little. Canada is hard pressed to keep it's helicopters flying. They don't have deep pockets, so their cooperation is mostly symbolic - which leaves me even more puzzled that Martin would want to stick his thumb in Bush's eye for no real benefit.
