Six Atlantic Canadian cleantech ventures have been named to the 2025 edition of the Foresight 50, an annual exercise to find the most investible cleantech companies in the country.

Calgary-based Foresight Canada, which bills itself as Canada’s largest cleantech innovation and adoption accelerator, released the list of 50 leading Canadian cleantech startups earlier this week. In a report detailing the group, Foresight said it chose the companies based on four criteria: the team; environmental impact; probability of success; and investment readiness.

David Sanguinetti, Interim CEO of Foresight Canada, said in a press release that the 50 companies are Canada’s most de-risked and scalable cleantech investment opportunities.

"These honourees represent some of the most exciting prospects coming out of Canada's cleantech ecosystem,” said Sanguinetti. “Their innovation is actively transforming traditional industries into new strengths, securing economic competitiveness, and creating positive change in our communities and daily lives.”

The organization said this year’s honourees collectively employ more than 770 full-time workers and have raised over $377 million to date. Since it began the Foresight 50 in 2021, the total honorees have raised more than $2.6 billion, the group said.
