Canada has been rocked by several incidents of mass violence in recent years, including a stabbing spree in a remote Saskatchewan Indigenous community on September 4 that left 10 dead and 18 wounded.
One of the suspects, in that case, was found dead, believed to have been murdered by his brother, who was later arrested after a four-day manhunt and died in custody.
A gunman masquerading as a policeman also killed 22 people in Nova Scotia in April 2020 — including a police officer — two years after a driver of a van killed 11 pedestrians in Toronto.
And another shooter killed six worshippers at a Quebec City mosque in January 2017.
