On 29 July 2026, Canada marked the 25th anniversary of the September 11 attacks. Mayor Mat Siscoe of St. Catharines said the lingering grief underscores the close relationship between Canadians and Americans, even as trade tensions continue. He announced a ceremony at the city’s 9/11 memorial trail, which honours both Canadian and U.S. victims.

The attacks killed almost 3,000 people in the United States. Police later estimated that about 80,000 people gathered on Parliament Hill for a national day of mourning. The Canadian Red Cross sent 146 volunteers to New York, and hundreds of Canadian firefighters and police officers assisted in recovery efforts.

At the end of the day, I think Canadians view American citizens as brothers and cousins and sisters.

  • All seven left‑rated outlets, The Toronto Star, Elora Fergus Today, Sudbury, Bay Today, Guelph Today, Timmins Today and The Hamilton Spectator, ran digests that reported the mayor’s comment that the lingering grief from the attacks reminded Canadians of strong Canada‑U.S. ties and noted the backdrop of a trade war. The digests highlighted the 25‑year milestone and the mayor’s call for remembrance, but they did not include the police crowd estimate, the volunteer figure, or details about the memorial trail.
