Lead pipe replacement law in Quebec
Quebec's Règlement sur la qualité de l'eau potable (RQEP) sets its own binding maximum lead concentration (5 µg/L, tightened from the prior standard in March 2021) with its own 30-minute-stagnation sampling protocol, and requires any municipality whose water doesn't meet it to file a lead action plan — which the regulation requires be published on the municipality's own website and updated annually. That's a publication requirement for a plan, not a mandate to publish a queryable address-level database. The City of Montreal's dataset goes beyond what's required; no other Quebec municipality, and no federal Canadian law, requires one.
