About Summerhill Estates

Summerhill Estates is divided into two sub-communities. Summerhill North is the established section, built primarily through the 1990s with well-maintained detached and semi-detached homes on quiet, well-organized streets. Summerhill South is the newer and still-developing portion, offering buyers the opportunity to purchase newer builds with modern floor plans while benefiting from the established Summerhill community infrastructure around them.

The community sits in a well-serviced part of southwest Newmarket with easy access to both Yonge Street commercial amenities and Bathurst Street corridor, while maintaining the residential quiet that families in this community specifically chose it for.

Why Buyers Choose Summerhill Estates

Summerhill Estates consistently attracts families who are price-conscious without being willing to compromise on community quality. They want strong schools, safe streets, accessible green space, and a neighbourhood where their children can grow up with other children. Summerhill delivers this without requiring a $2M+ budget.

The active development in Summerhill South also attracts buyers who want a new build but prefer to be embedded in an established community rather than a fully new subdivision. This is a relatively rare opportunity in Newmarket.
