Flu Season Arrives Early Across Canada
1 Oct
Summary
- Respiratory illnesses have started earlier than usual in several Canadian regions.
- Confirmed cases and hospitalizations are already reported on P.E.I.
- Vaccination programs are underway, prioritizing high-risk groups.
Respiratory illnesses have begun earlier than expected in several Canadian provinces. As of October 2026, health authorities on Prince Edward Island are already reporting confirmed cases and hospitalizations related to flu season. Regions including Alberta, British Columbia, and southwestern Ontario have also noted an increase in illnesses starting as early as September.
Yukon's chief medical officer confirmed lab cases of influenza A have been identified since mid-August, marking the early start of the respiratory virus season. While national circulation of COVID-19, influenza, and RSV has been low, surveillance data indicates a slight uptick.
Provinces are initiating vaccination programs, with a focus on vulnerable populations. This includes individuals aged 65 and older, those in long-term care, and people with underlying health conditions. Influenza vaccines are recommended for everyone six months and older, while RSV protection varies by province. Experts suggest that vaccination, staying home when sick, masking, and improving indoor air quality are effective measures against infection.
