Summary

Face masks are now mandatory in Quebec healthcare facilities.
An early flu outbreak is straining the region's emergency rooms.
Mask rules vary across eastern Ontario hospitals.

Face masks are once again required in healthcare settings across Western Quebec as an early surge in the flu season overwhelms regional emergency rooms. The Centre intégré de santé et de services de la région de l'Outaouais (CISSSO) implemented this new mandate on Tuesday, which will remain in effect indefinitely. This requirement extends to all hospitals, long-term care facilities, seniors' homes, and specific health centers like the Pierre-Janet mental health hospital.

The early onset of seasonal respiratory viruses has contributed to an increase in reported outbreaks and a significant rise in emergency room visits. Health officials are urging vigilance as they manage the current strain on medical resources. This proactive measure aims to curb further transmission within vulnerable populations.

In neighboring eastern Ontario, mask policies present a varied landscape. Some hospitals, like CHEO, have specific mask requirements in certain zones and recommendations for others. The Ottawa Hospital and Kingston Health Sciences Centre also enforce mask-wearing under particular circumstances, especially for patients exhibiting respiratory symptoms.
