At the start of the First World War, the 15th Light Horse was one of 6 cavalry regiments from across Western Canada to provide detachments that helped recruit the 6th Battalion (Fort Garrys), CEF for service with the first contingent of the Canadian Expeditionary Force. The other detachments were provided from the 34th Fort Garry Horse (now The Fort Garry Horse), the 20th Border Horse (now part of the 12th Manitoba Dragoons), the 18th Manitoba Mounted Rifles, the 32nd Manitoba Horse (now part of The Fort Garry Horse) and the 22nd Saskatchewan Light Horse (now part of The North Saskatchewan Regiment).{{Cite web |date=2016-10-03 |title=Perpetuated Units |url=https://fortgarryhorse.ca/wp/perpetuated-units/ |access-date=2022-06-03 |website=The Fort Garry Horse Museum & Archives |language=en-US}}
