As a Canadian: this response should not be downvoted. It is correct and important. The War Measures Act used during the October Crisis was a different law; the Emergencies Act, which was just invoked, was passed as a response to concerns about civil liberties and abuse of power under the WMA. Temporary laws made under the Emergencies Act are, unlike the WMA, subject to the Canadian Charter of Rights and Freedoms.
