CHF Canada is a sector organization, not an arm of government, but it will fund small projects from $500 to a limit of $4,000 to support the protection of the environment.
This program has been operating from some years and many co-ops have benefited from it. In a given year, an individual co-op can only make one application, but you can apply again in other years (even if you’re a previous recipient). There are some reporting requirements and all CHF Canada member housing co-ops can apply.
The application window can vary, but is generally open March and April. Funds are limited, Visit CHF Canada for more.
