The emergency medical infrastructure serving Montreal and Laval is facing a systemic shift as extreme weather patterns move from occasional anomalies to predictable crises. Urgences-santé, the region’s primary prehospital care provider, has reported a surge in 911 call volumes tied directly to climate volatility, prompting the organization to implement a first-of-its-kind climate resilience plan in North America.
This strategic pivot comes as the organization struggles to maintain response times during increasingly frequent “service ruptures”—critical gaps in availability caused by heatwaves, floods, and severe cold. For veterans of the service, the change is palpable. Jean-Pierre Rouleau, a communications center commander with 35 years of experience, including 25 years on the road, notes that the era of simply reacting to weather events has ended.
According to Rouleau, the organization previously managed these events without extensive formal planning, but such occurrences are no longer exceptions. The increasing intensity of these events has forced a total rethink of how the city manages its most critical lifeline, ensuring that the Urgences-santé climate change response can withstand not just current trends, but potential future catastrophes.
The breaking point: Records and ruptures
The volatility of the climate is already manifesting in the data. On January 11, 2024, a severe ice storm triggered a nearly 50% spike in emergency calls, setting a record for the organization. These surges are not merely about volume; they are about the complexity of the interventions. During heavy snowfall, ambulance deployments are slowed, evacuations become more challenging, and the time required to return vehicles to service is significantly extended.
Heatwaves present a different but equally lethal challenge. Unlike the immediate chaos of a storm, the impact of extreme heat often accumulates over several days as the population reaches a state of total exhaustion. This delayed effect creates a sustained pressure on the system that can last for a week or more.
To illustrate the scale of the challenge, the organization has tracked specific impact markers during extreme weather episodes:
| Event Type | Peak Call Volume | Key Medical Impact |
|---|---|---|
| Ice Storm (Jan 2024) | 1,473 calls/day | 50% increase over baseline |
| Extreme Heat | 1,335 calls/day | 2x increase in loss of consciousness |
| Extreme Cold/Winter | 1,411 calls/day | 3x increase in respiratory distress |
The baseline average for daily calls typically hovers around 1,000, meaning these events push the system nearly 50% beyond its standard operating capacity.
Preparing for the ‘apocalyptic’
In response, Urgences-santé has developed a resilience framework that extends far beyond typical weather forecasting. The plan analyzes a spectrum of high-impact, low-probability scenarios that the organization describes as nearly apocalyptic. These simulations include prolonged power outages, tornados, wildfires, extreme droughts, and zoonotic diseases jumping from animals to humans, as well as civil unrest and coups.
Rouleau emphasizes that the plan is designed to be exhaustive because the cost of being unprepared is too high. The framework incorporates a sophisticated monitoring system and is exploring the integration of artificial intelligence to predict medical surges based on real-time meteorological data.
This proactive stance is mirrored by the expansion of the Groupe d’intervention médicale tactique (GIMT). Often referred to as the SWAT team of Urgences-santé, these specialized “super paramedics” are trained for high-risk operations, including high-angle rescues and riverside interventions. The unit has grown from a small handful of specialists to several dozen in recent years, a growth directly attributed to the rise in major climate-driven emergencies.
A national crisis in a warming climate
The challenges facing Montreal are part of a broader national trend. According to data from the Climate Institute of Canada, Canada is warming more rapidly than almost any other region on Earth. The summer of 2024 was recorded as the hottest globally, and projections suggest that by 2050, many Canadian cities will experience four times as many days exceeding 30°C per year.
The human cost of this warming is already evident in Quebec. Heatwaves in the province result in an average of 470 deaths, 225 hospitalizations, and 36,000 emergency room visits. This translates to roughly 7,200 ambulance transports and 15,000 calls to Info-Santé during these periods.
climate shifts have more than doubled the risk of catastrophic wildfires across Canada, creating a new layer of respiratory and trauma-related emergencies that the prehospital system must now be equipped to handle on a permanent basis.
As Urgences-santé continues to refine its resilience model, the focus remains on the intersection of public health and environmental stability. The organization’s move toward AI-driven prediction and tactical expansion serves as a blueprint for other urban emergency services across North America facing similar environmental pressures.
The next phase of the resilience plan involves the integration of advanced weather-predictive tools into the dispatch center’s daily operations to better allocate resources before a heatwave or storm hits.
