Montreal health officials reported on Wednesday that emergency rooms across the city are functioning at more than double their usual capacity. The surge, measured at 200% of normal levels, is linked to an ongoing severe heat wave combined with staffing shortages in hospitals.

The extreme temperatures have increased the number of patients seeking care for heat-related illnesses, while the shortage of medical personnel has limited the ability of facilities to manage the influx. As a result, hospitals are experiencing prolonged wait times and strained resources.

In response to the situation, health authorities have issued an advisory directing seniors and individuals with respiratory conditions to take measures to stay cool. The guidance includes staying in air‑conditioned environments, staying hydrated, and limiting outdoor activity during the hottest parts of the day.

Hospital administrators indicated that the current capacity strain is affecting routine emergency services, with some departments redirecting non‑critical cases to alternative care sites. The health department continues to monitor the situation and is working to allocate additional staff where possible, though the shortage remains a significant challenge.

The heat wave, described by officials as severe, is expected to persist for several days, further testing the resilience of the city’s healthcare system. Residents are urged to follow the cooling recommendations to reduce the burden on emergency services and protect vulnerable populations.

Authorities emphasized that the combination of high temperatures and limited staffing has created an unprecedented demand for emergency care, prompting the call for community cooperation and personal precautionary steps.
