On June 11, 2026, the City of Montreal placed the borough of Lachine on a water‑conservation watch list, requiring residents to lower their potable‑water consumption. The action is part of a broader effort by municipal authorities to manage a shortage in Montreal’s drinking‑water system and to avoid the need to shut off the water network serving the area.
Montreal officials have warned that the city’s supply of safe drinking water is under strain, prompting a series of alerts to neighborhoods across the island. By adding Lachine to the watch list, the city signals that water use in the district must be reduced until conditions improve. The watch list does not impose fines but serves as a formal request for households and businesses to limit non‑essential water use.
City representatives indicated that the water‑conservation measures are preventive. They emphasized that the municipality cannot simply turn off the water service for Lachine, making voluntary reduction the primary tool to preserve the supply. The request follows similar appeals issued to other districts that have shown higher consumption rates amid the ongoing shortage.
Residents of Lachine are being asked to adopt practices such as shorter showers, using water‑efficient appliances, and limiting irrigation of gardens. While the city has not set a specific reduction target in this notice, the expectation is that collective effort will ease pressure on the system and help maintain continuous service.
The watch list remains in effect until the city announces that the drinking‑water supply has returned to stable levels. Authorities will continue to monitor usage across Montreal and may issue further guidance if the situation does not improve.
The current alert reflects the city’s strategy of encouraging conservation rather than resorting to service interruptions, aiming to safeguard the water network for all residents of Lachine and the wider Montreal region.
