The Regiment commemorates St Julien’s Day on the weekend closest to 22 April, commemorating the counter-attack by the 10th and 16th Battalions, CEF, on Kitcheners’ Wood on “The Glorious 22nd of April, 1915”. The occasion is marked by the annual reunion dinner of The Calgary Highlanders Regimental Association. The Regiment also exercises its right to the Freedom of the City of Calgary on this weekend by marching to church parade and a wreath laying at City Hall.

The Regiment also commemorates the Battle of Walcheren Causeway, one of many hard earned Battle Honours awarded to the Regiment for its service during the Second World War. The commemoration of this battle, on the weekend closest to 31 October, has traditionally included the participation of the Dutch community of Calgary.

The Regiment also participates in Remembrance Day services in communities throughout southern Alberta, from where the majority of their recruits were drawn during the Second World War.
