The Green Infrastructure Stream is a category within federal infrastructure funding programs that supports environmentally beneficial projects. Under the Investing in Canada Infrastructure Program and successor programs, the green infrastructure stream funds projects in areas like: water treatment and distribution, wastewater treatment, stormwater management, solid waste management, climate change adaptation and mitigation, community energy systems, and capacity building for asset management and climate planning. The stream recognizes that significant infrastructure investment is needed to reduce environmental impacts, adapt to climate change, and ensure sustainable communities. Projects apply through provincial intake processes established under bilateral agreements. The green infrastructure stream typically offers higher federal cost-sharing for climate adaptation projects and projects in smaller communities. Funding priorities and eligible project types evolve with federal priorities and program updates.
