Where is Summerhill Estates in Newmarket?

Summerhill Estates sits in Newmarket's southwest corner, bounded by Yonge Street on the east, Bathurst Street on the west, Mulock Drive on the north, and the Newmarket-Aurora town line on the south. The Mulock Park project, a 16-acre central park on the former Mulock family farm, is slated to open in 2026 as a significant new green space for residents.

What Kind of Homes Does Summerhill Estates Have?

Most housing was built in the early 2000s, featuring detached homes, semi-detached units, and freehold townhomes that are almost entirely brick with garages. The neighbourhood is denser and more efficiently designed than older Newmarket subdivisions, with ongoing infill development like Mulock Village adding newer construction.
