It began with a frightening sight on a late June morning. Around 11:35 a.m., someone walking in Montreal's Côte-des-Neiges neighborhood looked up at a local Hilton hotel and saw something terrifying: the barrel of a rifle sticking out of a window. The person immediately called the police, starting a chain of events that would break a long peace for the city's police force. When officers arrived on June 22, 2026, they found a trap instead of a normal emergency. Investigators believe the attacker deliberately targeted the police. A violent gunfight erupted, killing three people and shocking the diverse neighborhood known for its immigrant and Jewish communities. Among those killed was Mohamed Lamine Benredouane, a 34-year-old who had joined the Montreal police just five years before. The city had not lost an officer in the line of duty for almost 25 years. That streak ended in Côte-des-Neiges. "It's a very, very sad day. It's a nightmare," said Montreal Police Chief Fady Dagher. The police department released a statement calling Benredouane's death a "huge loss" and praising his "sense of duty, commitment and professionalism." The violence also killed a civilian, Michael Moshe Mizrahi, an Israeli citizen respected in the area and active in the local Jewish community and its Chabad organization. As the shooting happened, authorities locked down nearby schools and community buildings. The shooter was identified as Seth Hatfield, who had traveled from Lethbridge, Alberta, to carry out the attack. He had written a long document expressing extreme hatred towards women, police, Jewish people, and the adult entertainment industry, and calling for a violent overthrow of capitalism. The Royal Canadian Mounted Police warned other agencies about the document, fearing it could inspire similar attacks. Police at the scene shot and killed Hatfield. A second officer was seriously injured but is now stable, and a civilian had minor injuries. Quebec's independent police oversight agency is investigating, especially after videos appeared online that might show an officer firing at a civilian. Officials have not confirmed who shot Mizrahi. Prime Minister Mark Carney and Israel's Foreign Minister Gideon Sa'ar condemned the violence.
