9/11 and Canada
The terrorist attacks in the United States on 11 September 2001 had an immediate and profound impact on Canada. Twenty-four Canadians died in what became known as the "9/11" attacks. When the US closed its airspace, hundreds of planes carrying thousands of passengers were diverted to Canadian airports. In the weeks following, Canada passed controversial anti-terrorism laws and sent its first troops to Afghanistan as part of the “War on Terror.”
