1 Area Support Group was a formation within the Canadian Army, established in 1998 to provide logistical and administrative support to military units across Western Canada. Headquartered at Canadian Forces Base - CFB Edmonton, 1 ASG played a pivotal role in ensuring operational readiness and support for various units until its restructuring in 2013.
In 2013, as part of a broader reorganisation of the Canadian Army, 1 ASG was merged with Area Support Unit Edmonton to form the 3rd Canadian Division Support Group. This restructuring aimed to streamline support services and enhance operational efficiency across the division.
