Veterans Affairs Minister Kent Hehr is leading a Canadian government delegation to France to mark the 75th anniversary of the Dieppe raid during the Second World War.
The raid, launched on Aug. 19, 1942, would prove to be the bloodiest single day for Canada's military in the entire war.
The Prime Minister released a statement Saturday to honour the hundreds of Canadians who lost their lives in the battle.
Of the nearly 5,000 Canadian soldiers who took part in the ill-fated mission, more than half became casualties, and 916 would die on the rocky shore of Puys Beach on the northern coast of occupied France.
The beach landing was supposed to happen under the cover of darkness, but the Canadians, along with 1,000 British and 50 American soldiers, were late arriving on shore, and as the sun rose they were left exposed to withering fire from German troops on the cliffs above.
Justin Trudeau said the loss at Dieppe taught Allied forces valuable lessons, which he said helped "to turn the tide of the war on D-Day" less than two years later.
"As we commemorate the Dieppe Raid at events in Canada and France, I ask all Canadians to honour the people who gave so much at Dieppe, as well as their families at home who suffered the loss of their loved ones," Trudeau says.
Governor General David Johnston noted that this year marks the centennial anniversary of two great victories for Canada — the battles at Vimy Ridge and Passchendaele in the First World War — but it's equally important to remember the losses, like the one at Dieppe.
"We must never forget the terrible cost of armed conflict and ensure that future generations remember, lest we repeat the mistakes of the past," Johnston said in a statement.
Ceremonies honouring the soldiers' sacrifice are being held Saturday in Dieppe, Montreal, Calgary and on Sunday in Dieppe, New Brunswick.
