Anti-Terrorism Act (Canada)

The Canadian Anti-terrorism Act () (the "Act") was passed by the Parliament of Canada in response to the September 11, 2001, attacks in the United States. It received Royal Assent on December 18, 2001, as Bill C-36. The "omnibus bill" extended the powers of government and institutions within the Canadian security establishment to respond to the threat of terrorism. 
The expanded powers were highly controversial due to widely perceived incompatibility with the Canadian Charter of Rights and Freedoms, in particular for the Act's provisions allowing for 'secret' trials, preemptive detention and expansive security and surveillance powers.
Civic opposition.
The "Act"'s passage has been compared to the government's activation of the "War Measures Act" in accordance to terrorist activity by the FLQ.
It was opposed by Parliamentarians Marjory LeBreton and Andrew Telegdi, and criminal defense lawyer David Paciocco, amongst others. Ziyad Mia, of the Toronto Muslim Lawyers Association, "questioned whether the definition of terrorist activity would apply to a group that resisted, by acts of violence, the regimes of Saddam Hussein or Robert Mugabe," and pointed out that it criminalized the French Resistance and Nelson Mandela.
Prosecutions.
In January 2010, Zakaria Amara, from Mississauga, a suspect in the 2006 Toronto terrorism case, was sentenced to imprisonment for life. This sentence was the stiffest given so far under the Act. Saad Gaya from Oakville, a fellow suspect in the same case, was sentenced to 12 years in prison.
"Combating Terrorism Act" (2013).
Some of the bill's provisions were set to expire on March 1, 2007. The Harper government urged that these be renewed, while all three opposition parties were opposed. Specifically, the provisions had to do with preventative arrest and investigative hearings. On February 28, 2007, the House of Commons voted 159-124 against renewing the provisions, which later led to their expiry, as originally planned in the sunset clause.
In 2012, the Government of Canada introduced in the Senate of Canada Bill S-7, the "Combating Terrorism Act", which was to renew the expired provisions for a new five-year term, and introduced new crimes for leaving Canada to join or train with a terror group. The bill also increased the maximum prison sentences for some offences related to harbouring suspected terrorists. On April 19, just after the Boston Marathon bombing, the government rearranged the Parliamentary agenda to fast-track Bill S-7 to a vote on April 22 or 23, 2013. The "Act" received royal assent on April 25, 2013.
