The Tomb of the Unknown Soldier is a tomb situated before the National War Memorial in Confederation Square, Ottawa, Ontario. The tomb is dedicated to Canadian service members, and holds the remains of an unidentified Canadian soldier who died in France during the First World War; selected from a Commonwealth War Grave near Vimy, in the vicinity where the Battle of Vimy Ridge took place.
A tomb with an unidentified soldier was added to the National War Memorial in 2000, the culmination of a project begun by the Royal Canadian Legion. Since 2007, the Canadian Armed Forces have posted sentries at the tomb, and the National War Memorial, from April to November.
