Plumbers install, maintain, and repair piping systems for water, gas, drainage, and venting in residential, commercial, and industrial settings. The trade is regulated provincially with Red Seal recognition for inter-provincial mobility.

Canada faces a significant plumber shortage driven by residential construction demand, aging infrastructure replacement, and retirement of senior tradespeople. The median age of Canadian plumbers continues to rise, creating substantial replacement demand.
