The Land Alliance, representing five First Nations in Ontario, is opposing mining and extraction on unceded Indigenous lands without consent. A march called the March for the Land is being organized to pressure the Ontario government to respect Indigenous sovereignty and stop resource extraction. The article argues that capitalism depends on domination over land and resources, requiring the ongoing oppression and genocide of Indigenous peoples. It claims settler colonialism cannot reform itself and will always violate treaties and encroach on Indigenous land. The piece calls on the settler working class to support the land march and stand in solidarity with Indigenous people against the extraction-driven policies of Doug Ford's government. It notes that large shows of opposition have successfully pressured Ford to backtrack on policies in the past.
United action could challenge settler colonialism's theft of Indigenous land and positioning of the land as a resource rather than sacred living space.
