Rallies & Protests Against Forest Herbicide Spraying in Canada

This is what decades of being ignored looks like.

Across Canada, communities have protested forest herbicide spraying for generations. Concerned Citizens, Organizations, Indigenous Nations, Metis, Tribal Councils, TEK Elders, families, foragers, hunters, anglers, trappers, scientists and now Ontario Municipalities, have called for an end to chemical exposure in public forests.

These rallies are part of a very long public record of resistance. Coast to coast, people are not protesting because they misunderstand forestry. They are protesting because they understand exactly what is being sprayed ☠️, the damage it is doing, how Québec successfully ended chemical forestry in 2001, and who has been forced to live with 70 years of cumulative exposure.
