Again I'll explain. The North American Free Trade Agreement was an agreement that created obligations for the federal government and the country of Canada. This agreement doesn't actually create obligations for the Government of Canada. It creates obligations for the provinces, territories, and municipalities for their procurement processes. We cannot pass a law in the federal Parliament decreeing what provincial and territorial procurement practices will be. Only they can do that, and only they can assent to the voluntary provisions of an agreement like this. So that's why it's not the type of treaty that would typically be tabled in the House. It's not a federal obligation; it's a series of provincial and territorial obligations that have been assumed.
