I'm not familiar, Mr. Oliver, with any challenges to the Canada Health Act as a valid exercise of the federal spending power. There have been a number of challenges to other federal spending statutes in a variety of contexts. There's a significant body of case law now in which, for example, in the context of the Canada assistance plan, in the context of federal spending, and in the context of housing, where the courts have approved the exercise of the federal spending power in areas of exclusive provincial jurisdiction with conditions attached, the implication of those decisions, even though they're not dealing with the Canada Health Act itself, is the same reasoning that would lead to the conclusion that it's a valid exercise of the federal power.
