Clean Technology Funding in Ontario: Top Grants and Programs for Businesses
Ontario Clean Tech Grants and Incentives for Businesses
Ontario is one of Canada’s leading provinces for clean technology innovation and adoption. Home to a large base of manufacturers, tech companies, and innovative startups, Ontario has a strong interest in reducing emissions while growing the economy. For business owners and decision-makers in Ontario, there are many funding programs available to support clean tech initiatives – from installing energy-saving equipment in a factory to launching a new cleantech venture. Both the federal and Ontario governments offer grants, loans, and tax credits to help companies invest in sustainable technologies, improve energy efficiency, and adopt low-carbon solutions.
