Public health officials from Santé publique du Québec have formally criticised the City of Montreal for what they describe as an under‑estimation of the hazards associated with the Pierre‑Bédard sponge park. The criticism was issued on Thursday, 24 September 2026, after the agency reviewed the project’s risk assessment and concluded that the evaluation was insufficient.
The Pierre‑Bédard sponge park, located in Montreal, Quebec, is designed to manage a combined flow of stormwater and wastewater. City planners presented the park as a means to treat runoff, but health authorities argue that the potential risks of mixing these water sources were downplayed in the original analysis. Santé publique du Québec says the assessment failed to adequately address the possible health implications of exposing the public and the environment to untreated wastewater that may be present in the system.
In its statement, the public health agency emphasized that a thorough risk assessment is essential for projects that handle both stormwater and wastewater, given the potential for contamination and disease transmission. The agency’s concerns focus on the need for robust safeguards and monitoring to ensure that any contaminants are properly managed before the water is released or comes into contact with park users.
The City of Montreal has not yet responded to the agency’s remarks. The disagreement highlights a broader dialogue between municipal development initiatives and provincial health oversight, especially as urban areas adopt green infrastructure solutions to address water management challenges. The outcome of this dispute may influence how future sponge park projects are evaluated and regulated across the province.
Santé publique du Québec has called for a reassessment of the Pierre‑Bédard park’s risk profile, urging the city to incorporate more comprehensive health safeguards before the facility becomes operational.
