About This Show
AI-drafted summaryThe Canadian Mechanical & Plumbing Exhibition (CMPX) is Canada's largest trade show for the HVACR (heating, ventilation, air conditioning and refrigeration) and plumbing industries. 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 edition takes place March 22–24, 2028 at the Metro Toronto Convention Centre, South Building.
The show gathers over 500 leading brands showcasing the latest equipment, tools and technology for mechanical and plumbing professionals. Exhibits span heating, cooling, refrigeration and ventilation; plumbing, piping and pumps; indoor air and water quality; building automation and control; sustainability and energy efficiency; software, tools and instruments; and smart technology.
Attendees come to see new products in action, meet suppliers face-to-face, strengthen professional networks, and stay current on codes, technology and industry trends. Whether you're designing systems, installing them, or managing operations, CMPX is where progress happens — through products, people, and perspectives that drive what's next.
