April 9th
Vimy Ridge Day
Vimy Ridge Day is a day to commemorate the deaths and casualties of members of the Canadian Corps in the Battle of Vimy Ridge, which took place during First World War. The holiday has been observed annually on 9 April since 2003. It is a non-statutory observance.

Vimy Ridge Day remembers Canadians who fought in the battle of Vimy Ridge during World War I. The battle of Vimy Ridge, which was part of the larger battle of Arras in northern France, began on Easter Monday, which was April 9, in 1917. About 30,000 Canadians fought at Vimy Ridge and claimed victory. However, this victory came at a high cost. The Canadians suffered about 11,000 casualties. Of these, nearly 3,600 Canadians were killed.
At Vimy, regiments from coast to coast saw action together in a distinctly Canadian triumph, helping create a new and stronger sense of Canadian identity. After Vimy, the Canadian corps never looked back, and its success raised Canada’s international stature and earned a separate signature on the Treaty of Versailles that ended the war. In 2003 the Canadian government declared April 9 as “Vimy Ridge Day” to honor and remember the battle that took place at Vimy Ridge.
