Quebec is the most regulated construction market in Canada: nearly all contracting requires a provincial licence, site workers need competency certificates, and the industry runs on its own labour relations regime. Here is the 2026 map.
The RBQ licence: the entry ticket
The Régie du bâtiment du Québec licenses contractors for essentially all construction work, with subclasses matching each specialty. Getting one means passing exams (or qualifying an officer), proving solvency and posting licence security that customers can claim against. Electrical contractors obtain their licence through the Corporation des maîtres électriciens du Québec (CMEQ) and plumbing and heating contractors through the CMMTQ, the trade corporations that administer subclass 16 and 15 licences under RBQ oversight. Contracting without a licence brings heavy fines and unenforceable contracts.
CCQ cards and the labour regime
Work on sites governed by Act R-20 requires workers to hold CCQ competency certificates (journeyperson, occupation or apprentice), obtained through training or examination and tied to union membership choices, and hours are reported monthly to the CCQ. Residential renovation is partly outside the regime, but the boundaries are technical, so verify before staffing a job. Out-of-province contractors should budget real lead time for RBQ and CCQ processes.
Getting paid: the legal hypothec
Quebec civil law replaces liens with the legal hypothec of construction. Contractors, subs, suppliers and professionals can register one against the property for the value added by their work; subcontractors and suppliers must first have denounced their contract to the owner, and the hypothec must be published within 30 days after the end of the work, then enforced within set timeframes. New homes are covered by the mandatory GCR warranty plan.
CNESST and taxes
CNESST coverage is mandatory for employers, safety rules are enforced aggressively on Quebec sites, and invoices carry 5% GST plus 9.975% QST. Everything official runs in French, including the paperwork your crews will handle daily.

FAQs for Quebec trade businesses
Can I work in Quebec construction with a licence from another province?
Generally no. Quebec requires an RBQ contractor licence with its own exams, and workers on regulated sites need CCQ competency certificates. Labour mobility agreements help with recognition, but plan for the RBQ process before quoting Quebec work.
What is a legal hypothec?
Quebec’s equivalent of a construction lien. Contractors, subs and suppliers can register a hypothec against the property, but subs and suppliers must have denounced their contract to the owner, and the hypothec must be published within 30 days after the end of the work.
Why are CMEQ and CMMTQ different from the RBQ?
Electrical and plumbing contractor licences are administered by the trade corporations (CMEQ for electricians, CMMTQ for plumbers and heating) under RBQ oversight, so those trades apply through their corporation rather than the RBQ directly.
