What the Red Seal plumber exam measures
The Red Seal plumber exam is the Interprovincial (IP) Red Seal endorsement for the plumber trade in Canada. Red Seal is the national standard for skilled trades; passing the Red Seal exam grants the Red Seal endorsement, which allows the plumber to work in any Canadian province or territory without additional trade certification. The exam is administered by the Canadian Council of Directors of Apprenticeship (CCDA) and delivered by provincial apprenticeship authorities (Red Seal, September 2026). The exam covers four major blocks: plumbing theory and code (hydraulics, venting, water-service sizing, drainage), pipe-fitting and joining methods (soldering, brazing, threading, fusion welding, press-fit, push-fit), fixtures and appliances (water heaters, faucets, backflow preventers, gas appliances), and safety and codes (WHMIS, gas codes, building codes). The exam is multiple-choice with some diagram-based questions requiring calculation.
