Canadian Mechanical & Plumbing Expo (CMPX) – March 25 – 27, 2026 – Metro Toronto Convention Centre, South Building
The Canadian Mechanical and Plumbing Expo (CMPX) is Canada’s major 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. 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. The next CMPX takes place March 25–27, 2026 at the Metro Toronto Convention Centre, South Building.
