The flu season has hit Canada hard, and hospitals are feeling the strain. Emergency departments across the country are reporting overcrowding as a rapid surge in influenza cases collides with long-lasting fevers in both children and adults. While the latest federal report hints at a slight decline in flu activity nationwide, the situation remains critical in many regions.
But here’s where it gets controversial: despite the decline, parts of British Columbia, Alberta, Ontario, Quebec, and Prince Edward Island are still experiencing widespread flu activity. For the week ending December 27, 2025, a staggering 33.3% of flu tests came back positive—the highest rate in three years. By January 3, this number had dropped to 27.1%, but the impact on healthcare systems is undeniable.
The current outbreak is driven by the H3N2 subclade, known as K, which, according to the World Health Organization, doesn’t appear to cause more severe illness. However, this is the part most people miss: there’s a potential mismatch between this strain and the components targeted in this year’s flu shot. Infectious disease experts stress that the vaccine still offers protection against other flu subtypes and reduces the risk of severe outcomes like hospitalization. A U.K.-based study published in Eurosurveillance underscores this point, emphasizing its importance for all age groups.
Toronto’s North York General Hospital has been at the epicenter of this crisis. Dr. Kevin Wasko, chief of emergency medicine, notes that the early and intense flu season has overwhelmed the hospital. “Our wards are full,” he explains, “and many admitted patients are waiting in the emergency department for beds to become available.” On a recent Thursday, CBC News witnessed dozens of patients waiting to be triaged, with several lying on stretchers in hallways—a stark illustration of the strain on the system.
Here’s the bold truth: despite the chaos, Dr. Wasko urges, “If you need our services, don’t hesitate.” He emphasizes that anyone struggling to breathe, unable to keep food down, or too weak to perform daily activities should seek immediate care. The hospital aims to see 90% of patients within three hours, a goal they’re working hard to maintain.
In southwestern Ontario, Erie Shores Healthcare in Leamington is seeing a similar trend, with shorter wait times than North York but a notable increase in pediatric cases. Dr. Braedon Hendy, chief of emergency medicine, highlights the severity of influenza type A in children this year. “We’re seeing kids with fevers lasting five to seven days or more, along with gastrointestinal symptoms like diarrhea,” adds Mark McKelvie, a regional medical officer in Newfoundland.
And this is where it gets even more concerning: pediatric infectious disease specialists point out that most children haven’t been exposed to the H3N2 strain in recent years, as it hasn’t been the dominant strain for some time. This lack of immunity could explain the higher severity in pediatric cases.
Wastewater testing in Ontario, conducted by Professor Trevor Charles of the University of Waterloo, confirms that subclade K is the dominant strain. Early data suggests flu activity might be declining, but Charles cautions, “We need the latest data to confirm this trend, especially after holiday gatherings.”
New Brunswick Health Minister John Dornan blames the surge on low vaccination rates, calling the increase in preventable flu cases a major contributor to ER congestion. His statement raises a thought-provoking question: Should vaccination campaigns be more aggressive to prevent such crises in the future?
As hospitals grapple with this challenging flu season, the situation in Alberta has reached a breaking point, with physicians calling for a state of emergency due to overcrowded hospitals.
What do you think? Is the flu vaccine doing enough, or do we need a more proactive approach to prevent future surges? Share your thoughts in the comments below—let’s spark a conversation that could shape how we handle flu seasons to come.
