What’s happening and why now
The City of Montreal has issued an unprecedented public appeal for residents to slash water use this summer after an inspection revealed a 48-inch steel water pipe installed in 1984 is deteriorating rapidly. The pipe, which runs beneath Atwater Ave. between Sherbrooke St. and Workman St., is one of four that feed the McTavish reservoir, a critical drinking water basin for over a million people. With another 60-inch feeder pipe already under repair, only two of the original four supply lines will remain operational during the emergency work, which begins in the coming days and is expected to last six to eight weeks.
City officials have framed the situation as an "exceptional" crisis requiring "exceptional" measures. Executive committee member Alan DeSousa emphasized that while the city will implement targeted reductions—such as suspending routine water main flushing and street washing—success depends on widespread public cooperation. The timing of the shutdown, coinciding with the peak summer demand season, adds urgency to the call for conservation.
Background: A city built on aging infrastructure
Montreal’s water crisis is not an isolated incident but the latest symptom of a long-standing challenge: aging infrastructure. Roughly one-third of the city’s drinking water leaks out of decaying pipes before it reaches homes, a problem that has persisted despite ongoing repairs. The McTavish reservoir, fed by the compromised pipe, is one of the city’s primary water sources, serving 16 of Montreal’s 19 boroughs. The affected areas include densely populated neighborhoods like downtown, St-Henri, and parts of the Plateau, as well as six demerged suburbs such as Westmount and Côte-St-Luc. Only three boroughs and their surrounding suburbs are spared due to separate pumping stations.
Historically, Montrealers have used over 300 litres of water per person per day—well above the Canadian average of 220 litres. This profligacy, combined with the city’s leak-prone system, has left the water supply vulnerable during peak demand periods. The current emergency repairs follow a pattern seen in other North American cities, where decades-old infrastructure struggles to meet modern needs. For example, in 2019, Baltimore faced a similar crisis when a major water main break left thousands without water for days, highlighting the risks of deferred maintenance.
Who is affected and how
The call for reduced water use will impact a broad cross-section of Montreal’s population, from individual residents to large institutions and businesses. Households are being asked to limit outdoor watering, shorten showers, and avoid running taps unnecessarily. The city has also suspended non-essential water use, including decorative fountains and continuous street washing, to ease pressure on the system. While these measures may seem minor, their cumulative effect could determine whether the city avoids more severe restrictions, such as a full watering ban or fines.
Businesses and industrial users are not exempt from the call for conservation, though critics like Projet Montréal leader Ericka Alneus argue the burden has fallen disproportionately on residents. City officials have stated that industries and commercial enterprises have already been notified of restrictions, but the lack of detailed public guidance has raised concerns about enforcement and fairness. Firefighters, too, are watching closely. While the city claims the fire department will have sufficient resources, the Montreal Firefighters Association has warned that water shortages could force defensive firefighting tactics, potentially endangering lives and property.
Why it matters
This crisis extends beyond a temporary inconvenience; it underscores the fragility of urban infrastructure in an era of climate change and population growth. Montreal’s water system, much like those in other aging North American cities, was designed for a different era—one with lower demand and fewer extreme weather events. The current emergency repairs are a stopgap measure, but the underlying issue of deteriorating pipes and high leakage rates demands long-term investment. Failure to address these challenges could lead to more frequent disruptions, higher costs for repairs, and even public health risks if water quality is compromised.
Moreover, the crisis highlights the tension between individual responsibility and systemic accountability. While residents are being asked to change their habits, the root cause lies in decades of underinvestment in infrastructure. The situation also raises questions about equity: wealthier neighborhoods with separate water sources may face fewer immediate hardships, while lower-income areas could bear the brunt of any water restrictions or fines. As climate change intensifies heatwaves and droughts, cities like Montreal will need to balance short-term conservation efforts with long-term planning to ensure resilient water systems.
What happens next
Over the next six to eight weeks, the city will carry out emergency repairs on the compromised pipe while closely monitoring water consumption and infrastructure conditions. The goal is to reduce overall water use by 7%, a target officials believe is achievable with public cooperation. If consumption remains too high, the city has warned it may impose stricter measures, such as a watering ban or fines for excessive use. The fire department has assured residents it will have the resources needed to respond to emergencies, but firefighters’ unions have raised concerns about preparedness in the event of a major blaze.
The city will also need to address the broader issue of infrastructure decay. While the current repairs are critical, they are not a permanent solution. Montreal’s water system requires significant investment to modernize aging pipes and reduce leakage rates. In the meantime, residents and businesses should prepare for potential disruptions, particularly during heatwaves when demand peaks. The city has not specified whether additional measures will be needed beyond the summer, but officials have indicated they will reassess the situation as repairs progress.
