April 09, 2021 is Vimy Ridge Day! Since 2003 Canada observes this day as a commemoration of the Battle of Vimy Rice. This is not a public holiday, so there are no main celebrations taking place, but the Canadian flag is on half-mast on the Peace Tower of Parliament Day in Ottawa.
We have placed a detailed description of this event on this page: Vimy Ridge Day 2020. For further information please stop by there!
