Prime Minister Justin Trudeau has told his caucus he will invoke the never-before-used Emergencies Act to give the federal government extra powers to handle the protests across the country, according to sources.

Those sources, who were not authorized to speak publicly, said the prime minister will inform the premiers of his decision later today.

In a meeting with the Liberal caucus on Monday morning, Trudeau said there were no plans to deploy the military, according to the sources.

The Emergencies Act, which replaced the War Measures Act in the 1980s, defines a national emergency as a temporary "urgent and critical situation" that "seriously endangers the lives, health or safety of Canadians and is of such proportions or nature as to exceed the capacity or authority of a province to deal with it."

The act grants cabinet the ability to "take special temporary measures that may not be appropriate in normal times" to cope with an emergency and the resulting fallout during an "urgent and critical situation."

It also gives powers to the prime minister to respond to four different types of emergency scenarios: public welfare (natural disasters, disease), public order (civil unrest), international emergencies and war emergencies.
