The Emergency Measures Act is designed to consolidate power.
It strips Provinces of their decision making authority and hands it to Ottawa. To be clear, it does not magically create new powers as many Canadians think. The former Conservative Leader, Rona Ambrose, seems to believe the power to close provincial borders and decide which province gets what healthcare services, and how much they get, is best in the hands of Justin Trudeau.
Isolation is getting to people, clearly, but panic is no reason to hand Trudeau unfettered power.
Provincial governments, where necessary have already made unprecedented moves to protect their own people. It's how our decentralized confederation was designed to work.
The power to close provincial borders should rest in the hands of the people of that province, not with of the occupant of the Prime Minister's Office.
