Canadian Prime Minister Mark Carney called for vigilance as the country marked the 41st anniversary of its worst-ever terror attack, the bombing of Air India flight 182, the Kanishka, by Khalistani extremists on June 23, 1985.
In a statement, Carney said, "the legacy of Air India Flight 182 demands remembrance, but also vigilance."
Memorial events were held in Ottawa, Toronto, Montreal, Vancouver, and Ahakista in Ireland.
The bombing claimed 329 lives, including those of 268 Canadian citizens.
Canada's Minister of Public Safety Gary Anandasangaree was present at the Irish memorial, which was the first to be established.
Minister of Foreign Affairs Anita Anand said, "Canada will continue to work with allies and partners to confront terrorism and violent extremism, and always protect the safety of Canadians."
Representatives from the Canadian Government and law enforcement were present as India's High Commissioner to Ottawa Dinesh Patnaik paid tribute to the victims at the memorial in the capital.
