Ontario is Canada’s powerhouse for cleantech growth, and where the major advances in cleantech innovation are taking place.

Ontario has leaders in solar, hydrogen, biofuels, electric vehicles and smart energytechnologies—though perhaps best known for its expertise in water technology. Many of the biggest breakthroughs in water remediation have come from Ontario, including UV disinfection and membrane filtration, two of the most widely used technologies in the quest for clean water.

The province is also home to the world’s first all-electric, battery-powered underground mine, eliminating greenhouse gas emissions associated with moving materials. You can be confident that by locating your business in Ontario, you are part of an ecosystem at the forefront of environmental progress.

Ontario boasts a number of world-leading research institutes and technology incubators focused specifically on cleantech, as well as some of the best R&D incentives to be found anywhere. Our latest initiative is EaRTH District—a collaboration between the University of Toronto and Centennial College that’s advancing the cleantech sector’s development through research, academic programming and commercialization.

Ontario has developed a cluster of mines and mining expertise that is leading the world in underground electrification.
