Is it worth buying a Markham home backing onto a hydro corridor or the GO tracks?Homes backing onto hydro corridors or the Stouffville GO line often cost less than similar interior lots, which can open up a preferred neighbourhood. Trade-offs include train noise and frequency, sightlines to towers and a smaller pool of buyers at resale. Markham has whistle cessation at most Stouffville line crossings. Health Canada says there is no conclusive evidence of harm from power line fields at levels found in Canadian homes. Visit at rush hour before you decide.
For budget-conscious buyers, a home backing onto the hydro lines or the rail corridor can be the way into Unionville, Milliken, Raymerville or Cornell at a lower price.
Michael John Lau, a REALTOR® with the Kaizen Real Estate Team, one of the most active real estate teams in Markham and York Region, helps buyers compare these homes with interior lots on the same streets, using recent sales.
The value trade-off
Price gaps vary by street, view and how close the home is to the corridor. Compare recent sales of corridor-backing homes with similar interior homes nearby, not a city-wide rule of thumb. The same discount usually applies when you sell, so the value is in what you get today.
Trains on the Stouffville line
- Metrolinx plans two-way, all-day service on core segments every 15 minutes or better, including to Unionville.
- Markham has whistle cessation at 15 Stouffville line crossings, including Main Street Unionville, Highway 7 and 16th Avenue.
- Ninth Line is the last crossing awaiting upgrades, now expected in 2026.
More frequent trains can mean more noise and also better transit. Visit at different times of day.
Hydro corridors and EMF
Health Canada says it does not consider precautions necessary for everyday exposure to power line fields, and that there is no conclusive evidence of harm at levels found in Canadian homes, including just outside corridors. Some buyers still prefer to avoid them, which affects resale.
