Mr. Speaker, in this very decentralized federation, Canada must speak as one if there is to be an effective foreign policy.
This is why the Canadian government is empowered, under the Constitution, to sign treaties in all areas of jurisdiction.
This being said, if a province does not like the content of a treaty, it does not have to implement it in its jurisdictions. But to avoid that, we must consult extensively, and this is what the Minister for International Trade is doing in relation to the Quebec City summit.
