This is an article by Ryan Alford, professor of law at Lakehead University in Ontario and appears in Newsweek. From the article:
First, the Emergencies Act specifies that only certain types of threats to public order can authorize emergency powers—which is why an order issued by the Governor General on Tuesday made the shocking allegation that the Freedom Convoy’s activities are “directed toward or in support” of terrorism.
It’s an astonishing claim for those who have been following the protests both in Canada’s capital and at border crossings closely. There is not a single violent incident that could possibly support a legally sufficient argument that the protests have been in support of or connected with terrorism.
Unfortunately, as is also happening in the U.S., the constitution and rule of law matter less and less.
