The Canadian Mechanical and Plumbing Expo (CMPX) is Canada’s ultimate industry event for HVACR and plumbing professionals. Held every two years, CMPX brings together the entire value chain — from manufacturers, contractors, and wholesalers to engineers, architects, educators, and students — to innovate, explore, connect, and learn.

The next CMPX takes place March 25–27, 2026 at the Metro Toronto Convention Centre, South Building.
CMPX is proudly co-produced by the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI) and the Canadian Institute of Plumbing & Heating (CIPH). Together, these associations represent decades of leadership, advocacy, and technical expertise, ensuring CMPX remains a must-attend event for professionals across the mechanical and plumbing industries.
