Flu Season Likely Peaked in Parts of Canada but Nationwide Cases Still High

Canada’s 2025‑26 flu season appears to have reached its peak in at least two provinces, while national influenza activity remains high but is showing signs of stabilizing, according to the latest federal data.

Influenza positivity rates — the share of flu tests that come back positive — hit a multi‑year high of 33% during the week of Christmas, before dropping to around 27% in the first week of January. In Ontario, public health officials say test positivity peaked around Dec. 21 and has since declined by about 10%, suggesting the worst part of the seasonal wave may be over in the province.

Similarly, health officials in Alberta report that influenza A activity has likely peaked, with case counts and hospital admissions beginning to ease. However, influenza A levels remain elevated and a potential rise in influenza B later in the season could extend circulation.

Despite signs of decline, public health experts emphasize that flu activity is still widespread, and many regions are experiencing high case numbers and pressure on hospitals.

Officials continue to recommend vaccination and basic precautions like staying home when sick, as substantial influenza circulation is expected for several more weeks.
