Investigators have recovered a pellet gun from the scene where Toronto police shot and killed a man suspected of carrying a rifle, an incident that prompted five nearby schools to be placed under precautionary lockdowns.

Police went to the Scarborough neighbourhood on Thursday after receiving several 911 calls about a man walking with a rifle and located him shortly after, Ontario province’s special investigations unit (SIU) said in a statement on Friday. The man, 27, was pronounced dead about 20 minutes later.

Toronto’s police chief, James Ramer, told reporters that officers responding to the calls were confronted by the man, but had declined to give further details, citing an ongoing investigation. This was after police said on Twitter that officers had fired and injured the suspect.

The incident occurred days after a gunman in Texas killed 19 children and two teachers at an elementary school. The Texas shooting raised more concerns about growing gun violence.

Mass shootings are rare in Canada, where gun control laws are stricter than in the United States.

The investigation is ongoing and a postmortem exam is scheduled for Saturday, said the SIU, which is an independent government agency tasked with investigating the conduct of officials, including police officers.

The SIU aims to complete its investigation within 120 days, but the time can vary depending on the case.

Canada’s rate of firearm homicides is 0.5 per 100,000 people, far lower than the US rate of 4.12, according to a 2021 analysis by the University of Washington’s Institute for Health Metrics and Evaluation.
