Have al-Qaeda cells operated in Canada?
Yes, experts say. In December 1999, U.S. border officials apprehended Ahmed Ressam, an Algerian national who was later convicted of trying to enter the United States with bomb-making materials. Ressam belonged to a Montreal-based terrorist cell thought to be linked to Algeria?s extremist Armed Islamic Group, an organization with ties to al-Qaeda. Counterterrorism experts think that Ressam?s cell hoped to perpetrate a millennium terror attack at Los Angeles International Airport, and some experts suspect that al-Qaeda cells remain in Canada. In June 2002, Canadian authorities arrested an Algerian-born Montreal resident who allegedly forged documents as part of a plot to bomb the U.S. embassy in Paris.
Have other terrorist groups besides al-Qaeda been active in Canada?
Yes. A former Canadian intelligence official told 60 Minutes that an estimated 50 known terrorist organizations, including Hamas and the Irish Republican Army, maintain presences in Canada, but Canadian intelligence officials dispute that assessment.
Canada has also faced domestic terrorism from the Front de Liberation du Quebec (FLQ), which sought to turn the largely French-speaking province of Quebec into an independent state and set off dozens of bombs during the 1960s. Following the FLQ?s October 1970 kidnapping of Quebec?s labor and immigration minister, then Prime Minister Pierre Trudeau invoked the War Measures Act to protect other potential FLQ targets and prevent further acts of terror. The minister was found dead a week later, and his kidnappers were subsequently tried and convicted. The FLQ has not been active for decades.
