Prime Minister Justin Trudeau will reportedly make history on Monday, with various sources confirming speculation that the federal government will invoke the Emergencies Act in response to the ongoing trucker convoy protest in Ottawa.

It's the first time the act will be invoked since receiving royal assent in 1988, replacing the War Measures Act, which authorizes temporary measures to guarantee national security during emergencies of public welfare, public order, international crises, and war.

Unlike the previous act, temporary measures taken under the Emergencies Act are subject to the Charter of Rights and Freedoms, limiting the federal government's ability to suspend civil liberties.

Still, this is the harshest response possible for the fed, the act reserved for emergencies that threaten the "safety and security of the individual, the protection of the values of the body politic and the preservation of the sovereignty, security and territorial integrity of the state are fundamental obligations of government."

Before I see a bad take: no, the Emergencies Act does not suspend the Charter. In fact, the preamble to the Act explicitly subjects the decision to enact it as subject to Charter rights.

The language in the act regarding suspensions of civil liberties is clear, but this hasn't stopped many aligned with the so-called "Freedom movement" from ringing alarm bells and accusing the Liberal government of authoritarianism.

When you have to evoke the Emergencies Act you know that you are losing power to control us.We will no longer acquiesce. Your actions are an unprecedented abuse of rights& freedoms as enshrined in our Charter. You don’t have omnipresent powers. We will hold you all accountable !

It's a move that's been expected for a few days now, rumours reaching a fever pitch on Sunday evening when the PM met with the Incident Response Group to the rapidly-evolving demonstrations. 

Today, I convened another Incident Response Group meeting. We covered further actions the government can take to help end the blockades and occupations. We’ll keep working urgently on this – to protect jobs, public safety, our neighbourhoods, and our economy.

News that Trudeau would invoke the Emergencies Act was confirmed to various media sources on Monday morning in a widely-expected response that has had the act trending by name on Twitter since Sunday evening.

The PM has reportedly been in calls with provincial premiers all Monday morning, with the announcement of the measures considered imminent.

The extreme move continues an interesting legacy for the Trudeau political dynasty.

Justin Trudeau has followed in the footsteps of his father, former PM Pierre Trudeau, who was the first and only Prime Minister to use the previous War Measures Act in peacetime during the 1970 October Crisis.
