This is not a conflicts clause. This is not a clause that addresses any real or perceived conflicts between different agreements the government may enter into. That's not what it's about. It's about making clear, just as a matter of construction, that Parliament has the authority, whether the act says so or doesn't say so, to implement by legislation provisions of the agreement or related agreements, or to fulfill obligations that Canada has undertaken under those agreements. That's what it says.
