This strain of Canadian federalism is strictly against reopening the Constitution and supports policies of shared and exclusive provincial jurisdiction in areas such as taxation, healthcare and immigration. They defend the federal government occasionally encroaching on areas that Quebec governments (both federalist and sovereigntist) consider their rightful jurisdiction. In general, federalists of this school of thought are opposed to officially recognising Quebec as a "nation" or "distinct society" within Canada, and support the Clarity Act (legislation introduced by the Chrétien government, essentially giving the federal government the right to establish a "clear majority" threshold for any sovereignty referendum at its own discretion and after the fact - this is opposed by the Quebec Liberal Party).
