About This Listing

A rare end-unit townhome backing onto green space and the newly redesigned Mulock Park (opening 2026), offering an exceptional combination of space, privacy, and lifestyle not often found in this price range. With significantly more living space and outdoor area than many nearby townhomes, this property stands out as a compelling value in today's market. Set on a premium lot with no rear neighbours, this home offers almost 1,900 sq ft of well-designed living space-larger than many comparable homes-with windows on three sides that fill the interior with natural light throughout the day. The open-concept kitchen and family room create an inviting central hub for everyday living and entertaining, with a seamless walkout to a private, fully fenced backyard and expansive deck-perfect for relaxing or hosting while overlooking peaceful green space. Upstairs, a versatile landing provides flexibility for a home office or reading nook, while the generously sized primary suite features a walk-in closet and ensuite with soaker tub and separate shower. Thoughtfully maintained and move-in ready, this home offers immediate comfort with the added benefit of a setting that is difficult to replicate, along with future park amenities that will continue to enhance the neighbourhood. Ideally located just a 10-minute walk to Yonge Street, Clearmeadow PS, and Sir William Mulock SS, this is a unique opportunity to own a larger, park-backing townhome in a location where space and privacy are increasingly hard to find.
