Cornerstone is Primont’s new master-planned community in Heritage Heights, the last large greenfield area of northwest Brampton, along Mississauga Road near the Caledon and Halton Hills borders. The first district, arranged around a central pond, offers double-car back-to-back, traditional and dual-front townhomes plus detached homes on 33 and 36 foot lots, with in-law suite and separate entrance options. Later districts are planned to add condominiums.
Cornerstone suits first-time buyers using the 5 percent deposit and multigenerational households who need a secondary suite. Mount Pleasant GO on the Kitchener line is the nearest station, Highway 407 and Highway 410 connect through Bovaird Drive and Mayfield Road, and the proposed Highway 413 corridor runs just north. Cassie Campbell Community Centre, Creditview Sandalwood Park and the Credit River valley are close. Mount Pleasant Village Public School and St. Edmund Campion Secondary School serve the area. The presentation centre is at 2005 Wanless Drive.
