From the residential band
The per-square-foot figures come straight from the curated Montreal hard-cost bands, taken at 1% for a new build and 5% for a fit-out. Nothing on this page is a separate estimate — it is the same market data, sliced by trade.
Local context: Quebec's unionised construction regime sets predictable labour rates, and land servicing contributions are lower than Ontario development charges.

What moves demolition and abatement pricing here
Tipping fees vary widely by municipality and are a direct pass-through. Asbestos, lead and mould in a pre-1990 building can exceed the demolition itself. Occupied buildings need hoarding, negative air and after-hours work. Salvage and diversion targets add sorting labour, and sorting is labour.
