On August 16, 2026, residents and activists gathered in Blainville, Quebec, to demonstrate against the planned expansion of the Stablex hazardous waste landfill. The protest targeted the US‑owned company’s proposal to enlarge the site that lies near residential neighborhoods, raising concerns about potential exposure to toxic chemicals.
Demonstrators described the proximity of the landfill to homes as a primary health risk, arguing that the addition of more waste storage capacity would increase the likelihood of chemical releases into the air and groundwater. They cited the location’s closeness to schools and community centers, emphasizing that families could be affected by any accidental spills or emissions.
Stablex, which operates the landfill on the outskirts of Montreal, has submitted expansion plans to municipal authorities. The company maintains that the facility complies with provincial environmental regulations and that the additional capacity is needed to manage hazardous waste generated by industrial activities in the region. Officials have not yet issued a final decision on the proposal, and the company has scheduled a public hearing later this month to address community concerns.
The mayor of Blainville said the council will examine the environmental impact assessment before deciding on the expansion, emphasizing the need to protect public health.
The opposition in Blainville reflects broader unease about hazardous waste sites owned by foreign firms operating in Quebec. Local groups have organized petitions and town‑hall meetings in recent months, seeking to pressure regulators to reject the expansion. As the debate continues, residents say they will maintain their presence at the site until authorities provide a clear answer on whether the landfill will be allowed to grow.
