Allandale Heights, in southeast Barrie, is located "up the hill" from Allandale and Allandale Centre, and is a newer residential area than the area of "Old Allandale." It is a family-oriented area, with detached homes, mature trees, and parks, with Lackie's Bush forming part of the southern border. Bordered by Highway 400 on the west, Allandale Heights has commercial properties in that region, along Fairview Road.
