Canadian Centre for the Great War

The Montreal-based Canadian Centre for the Great War exists to preserve and protect artifacts and archives related to the Canadian experience of the First World War, and inform Canadians of the same.
Although the physical centre has limited opening hours, Fridays and Saturdays, there is a website that may prove useful in exploring the likely experiences of your Great War warrior.
Look under Special Presentations, Exhibitions, and Centennial Stories for items of possible interest. The Catalogue leads to various photos and other images, conveying the dreariness of the situation, any one of which could be pertinent to your Canadian Great War soldier.
