On Sept. 14, 2001, more than 100,000 people gathered on Parliament Hill in Ottawa for a memorial service honouring the victims of the Sept. 11 terrorist attacks in the United States, three days earlier. Prime Minister Jean Chretien and former governor general Adrienne Clarkson attended the service, which was broadcast live across the country.
The crowd was among the largest ever assembled on the Hill. Paul Martin, who would become prime minister in 2003, later called it the largest single vigil the nation’s capital had ever seen. Canadians had spent the three days since the attacks absorbing the scale of the loss, including the deaths of at least 24 Canadian citizens in the World Trade Center and aboard the hijacked flights, and the vigil became the country’s central act of public mourning.
The date was not arbitrary. Sept. 14, 2001, had been designated a National Day of Mourning across Canada, with simultaneous observances held in cities and towns nationwide. In Ottawa specifically, the federal government organized the Parliament Hill service as the focal point, timed to coincide with a similar memorial service at Washington National Cathedral in the United States, which much of the world watched alongside the Ottawa broadcast.
The scale of the Ottawa gathering reflected more than sympathy for a neighbouring country. Canada’s own aviation system had been thrown into the crisis directly: in the hours after the attacks, more than 200 international flights bound for the United States were diverted to Canadian airports under what became known as Operation Yellow Ribbon, stranding roughly 33,000 passengers in communities from Gander, Newfoundland, to Vancouver. Many Canadians had spent the prior three days housing strangers, following rolling news coverage, and absorbing a security shock that closed the Canada-U.S. border to ordinary traffic for hours. The Parliament Hill vigil arrived as a release point for that tension, a single, shared moment after days of disrupted routine and uncertainty.
The event also set a marker for how Canada would formally observe the day going forward. Sept. 11 anniversaries in the years since have typically drawn smaller, more localized ceremonies, at Parliament Hill, at Canadian embassies, and at memorials built specifically to the day, including a permanent 9/11 memorial later established in Canada. But none matched the raw scale of the crowd that filled the Hill on Sept. 14, 2001, a single afternoon when the seat of Canadian government became the country’s main gathering point for collective grief over an attack that took place entirely on foreign soil.
