Calgary Health Region was formerly the governing body for healthcare regulation in an area of the Canadian province of Alberta.
The entire region was a member of the Planetree Alliance, a nonprofit association of health-care institutions, set up to promote practices to make patients less intimidated and more comfortable with the health care they receive.
[2] The Sheldon M. Chumir Centre and Richmond Road Diagnostic Centre (located in the old Alberta Children's Hospital building) became new care facility additions to the Calgary Health Region before the reorganization.
The CHR was formerly known as Calgary Regional Health Authority (CRHA) until 2000 when it adopted its new designation.
In 2009 sites and services within the former Region were renamed within AHS, many becoming part of the new Calgary Zone.
