Ontario Cleantech Expansion: Why 2025 Is the Year to Grow Your Startup

The world is investing in climate technology at an unprecedented pace, with over $1 trillion globally last year. If you’re building for impact, Ontario gives you a policy-aligned and innovation-ready springboard into North America.

Ontario offers a unique value proposition for cleantech founders: a launchpad into North America backed by policy stability, commercial opportunity, and strong public and private innovation efforts.

Ontario: Canada’s Cleantech Powerhouse

Ontario stands as a leader in Canada’s cleantech sector, housing over 850 pure-play cleantech companies. These companies span many sub-sectors, including renewable energy, energy efficiency, water and wastewater, and waste management, contributing significantly to the province’s economic landscape.

In 2024, Ontario businesses sold $27.5 billion worth of environmental and clean technology goods and services, the highest among all provinces. This figure represents a substantial portion of Canada’s total cleantech revenue, highlighting Ontario’s pivotal role in the sector.

The province’s cleantech industry also boasts a robust employment rate, with approximately 136,000 individuals employed in the sector. This workforce is supported by a network of over 5,000 cleantech and environmental companies, underscoring the industry’s capacity to generate significant employment opportunities.

Government Support Fuels Innovation

Ontario’s commitment to cleantech innovation is evident through various supportive programs and initiatives. The province’s cleantech sector contributes approximately $27.5 billion to Ontario’s GDP, with a significant portion attributed to clean technology services.

Government-backed organizations such as the Ontario Clean Technology Industry Association (OCTIA) and the Ontario Water Consortium (OWC) play crucial roles in fostering cleantech innovation. These organizations provide resources, networking opportunities, and support to cleantech startups, facilitating their growth within the province. Additionally, the new NRC IRAP Clean Technology initiative offers significant funding opportunities for cleantech startups, providing grants that cover a portion of project costs to help advance sustainable technologies. These programs are expected to launch in early 2025-2026, creating more avenues for startups to access critical support.

Toronto: A Thriving Startup Ecosystem

Toronto, Ontario’s capital, is recognized as a leading startup hub in Canada. The city is home to a vibrant ecosystem that supports over 2,000 tech startups, offering a conducive environment for innovation and business growth.

The Toronto region attracted CA$3.7 billion in venture capital investments in 2022, more than doubling the amount raised in 2019. This influx of capital underscores the city’s appeal to investors and entrepreneurs alike.

Additionally, Toronto’s diverse talent pool, bolstered by world-class universities and a welcoming immigration policy, ensures that startups have access to skilled professionals across various domains. The city’s affordability in tech talent further enhances its attractiveness as a destination for startups seeking to build and scale their teams.

Strategic Advantages of Expanding to Ontario


1. Access to Skilled Talent

Ontario’s educational institutions and immigration-friendly policies ensure a steady pipeline of engineers, data scientists, and cleantech experts. This talent pool is crucial for startups aiming to innovate and scale effectively.

2. Robust Government Support

Programs like the Scientific Research and Experimental Development (SR&ED) tax credit and Regional Innovation Centres provide grants, mentorship, and resources to startups. These initiatives reduce financial barriers and accelerate the commercialization of new technologies.

3. Strategic Market Access

Ontario’s location offers proximity to the vast North American market and benefits from trade agreements like USMCA and CETA, easing export and scaling efforts. This strategic positioning facilitates access to key markets and international partners.

4. Vibrant Ecosystem

A growing number of accelerators, incubators, and corporate partnerships foster collaboration, funding, and market entry opportunities. Organizations such as MaRS Discovery District and the Ontario Water Consortium provide platforms for startups to connect with industry leaders and potential investors.

Success Stories from Ontario’s Cleantech Sector

Ontario’s cleantech sector has produced several notable success stories, demonstrating the province’s capacity to nurture innovative companies.

GreenMantra Technologies, based in Brantford, Ontario, specializes in converting recycled plastics into value-added synthetic waxes and specialty polymers. Their innovative approach contributes to a circular economy by upcycling waste materials into high-value products.

Bullfrog Power, headquartered in Toronto, is a green energy retailer offering renewable electricity and natural gas. The company sources its energy exclusively from wind, solar, and low-impact hydro facilities, providing sustainable energy solutions to its customers.

These companies exemplify the innovative spirit and entrepreneurial success within Ontario’s cleantech ecosystem.

Why Ontario Stands Out for Cleantech Startups

Ontario’s robust cleantech sector, supportive government programs, access to skilled talent, and a thriving startup ecosystem makes it an ideal location for cleantech startups aiming to expand into North America.

The province’s commitment to innovation and sustainability, coupled with its strategic market access and supportive infrastructure, provides a conducive environment for startups to grow and succeed.
