About OCTIA

OCTIA’s current membership comprises cleantech ecosystem participants driving proprietary, innovative technologies that have a meaningful environmental benefit, includes all sectors of the economy, and ranges from start-ups to large public companies.

OCTIA links its members to valuable resources, expert guidance, and exciting networking opportunities. With events designed for peer learning and growth, OCTIA offers essential support for companies navigating the challenges of each stage in their development, backed by members who have already “been there”!

Most importantly, especially in this critical election year for Canada and Ontario, OCTIA advocates effectively for our industry, working with policymakers and regulators to create a supportive environment for cleantech growth in Ontario.

The global cleantech market is growing rapidly; the market for clean energy technologies alone is projected to more-than-double by 2030, to $970B, and generate 14 million jobs (IEA 2023).

Many Canadian industries are making major low carbon investments, especially in Ontario (auto, steel, cement, aluminum).

To take full advantage of this opportunity, Ontario’s clean technology sector needs a unified voice. We need to promote our good work, continue to attract top talent, and secure support to grow leading companies. Our sector also needs a seat at decision-making tables. It’s time for Canada’s largest and most industrialized province to champion the clean technology sector.

Formed by experienced clean technology leaders in January 2019, the Ontario Clean Technology Industry Association (OCTIA), aims to be that voice and champion.

Together, OCTIA members are committed to building support for this high-potential, globally competitive sector – for the benefit of the environment and Ontario’s and Canada’s future economy.

• Canada has 2,427 cleantech firms (Natural Resources Canada, 2025) across the country who contribute $40.6 billion (Natural Resources Canada, 2025) to the Canadian economy.
• Cleantech companies exported $9.8 billion worth of goods (Natural Resources Canada, 2025) with 77% of these exports going to the US.
• This contributes to the sector’s fast growth with over 220,000 people employed (Natural Resources Canada, 2025), an increase of close to 20% since 2020.
• Clean technology supports all other economic sectors, including agriculture, resources, manufacturing, and oil & gas.
• Ontario is rich in minerals and natural resources that are key inputs, like critical minerals, for multiple clean technology applications.
• Ontario has the largest university network in Canada generating bright and capable young human resources and leaders for the cleantech sector.
• Ontario has deep competencies in a variety of key cleantech sectors: Hydrogen, Green Chemistry, Energy Storage, Transportation, CCUS, Nuclear Power, Waste to Value and Water.

Clean Technology

Clean technology, or cleantech, includes novel services, processes, products, and activities that improve economic performance and significantly reduce environmental impacts. In general, this includes, but is not limited to, better solutions for energy use, water management, food production, and transportation.

As the world transitions to a clean growth economy, Ontario has significant potential to contribute to the shift.
