OCTIA & Ontario’s Clean Technology Sector


Canada’s environment and clean technology (ECT) sector is worth $73B (2.9% of GDP), and it creates 314,257 jobs (StatsCan 2022). The manufacturing part of ECT is worth $33.6B – 28% of that is exports. “Pure-play” cleantech companies accounted for 210,00 jobs in 2022. This number is projected to grow to half-a-million by 2030.

Cleantech also accounted for nearly $14.3 billion in exports in 2020. They are projected to reach a volume of $20 billion by 2025.

Canada has 12 of the Global Cleantech 100 firms – three of them are from Ontario. It is now ranked #2 in the global Cleantech Innovation Index (a measure of future potential).

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.

Our mandate is to:

  • Strengthen, foster, and promote Ontario’s cleantech community.
  • Build partnerships and networks to generate quality business opportunities.
  • Encourage industry and government leaders to act in support of Ontario’s cleantech sector.

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.

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.
