End-unit freehold townhouse in Patterson. Researched 2026-11-04 from listing sites, public agencies and maps; no inspection, survey or expert source.
Bottom line
Looks worth viewing: the ask is $84,500 below the closest-matching recent sale and $72,000 below the area median for freehold townhouses. The ask is also $307,000 below the 2023 sale price, and no source explains that drop or the $211,000 relisting cut in 16 days.
Recommendation
Suggestion: view it, then clear these four checks before committing. This assumes a family home with four real bedrooms and a car or GO commute, and no reliance on basement rent. Your goals may change this.
Title: have a lawyer read the easements and rights-of-way in the legal description.
Landfill: ask the City of Toronto or the Ontario environment ministry for current gas and groundwater monitoring on Keele Valley, about 1.2 km north.
Noise: stand on the lot at rush hour; Major Mackenzie Drive is 78 m north.
History: ask why the $1,299,000 listing ended, and ask for Schedule D (inclusions and exclusions).
