Upon completion, the site was taken over by the Government of Canada to serve as a military convalescent hospital for soldiers wounded in the First World War.

Canadian alternative rock band Billy Talent shot their music video for Try Honesty in one of the old buildings in 2003, before they were torn down in 2005–6.
