Licensing and regulators in Quebec
Plumbing and heating contractors in Quebec get their licence (subcategories 15.1 to 15.5) from the Corporation des maîtres mécaniciens en tuyauterie du Québec (CMMTQ), which issues it on the government’s behalf (RBQ plumbing licence page). Tradespeople on residential sites need a competency card from the Commission de la construction du Québec (CCQ).
Lynknester licence-checks pros in licensed trades against the official register before they are matched to jobs. We don’t verify insurance — ask your pro for their certificate.
Permits in Montreal
Start with Ville de Montréal permits (issued by your borough). Whether a permit is needed depends on the work; ask your pro who pulls it and build the inspection time into the schedule. Before any digging, request utility locates from Info-Excavation. For workplace insurance, check CNESST coverage.
Local and seasonal issues in Montreal
Montreal’s plexes often share plumbing risers between units, and old cast-iron drains are common. Owners must replace the private part of a lead water service, and the City replaces the public part (Ville de Montréal: lead in water).
What affects the cost
We don’t show a price range here: we haven’t found a reliable public source for Montreal plumbing prices, and we won’t make one up. Prices depend on pipe material and access (finished walls or ceilings), permit and inspection fees, emergency or after-hours calls, and the age of the drain or water service. Get at least two written quotes that spell out scope, materials, permits and payment terms.
