Canadian respiratory virus surveillance report: Snapshot

Overview of key trends in the activity of respiratory viruses, such as influenza (flu), COVID-19, and respiratory syncytial virus (RSV) in Canada.

Update schedule: This page was last updated on ..., with data up to and including ... (surveillance week ...).

This summary tab provides high level trends for COVID-19, influenza, RSV, and other seasonal respiratory viruses. For more detailed trends on each virus, refer to the individual virus tabs at the top of the page.

Activity levels

Figure 1: Map of activity levels by province and territory in Canada, week (week ending )

Hover over the map to explore the respiratory virus activity levels in each province and territory.

Data note: Activity levels are generated with a method adapted from the Moving Epidemic Method (MEM) using laboratory percent-positivity data. Cut-points are calculated separately for each province and territory based on their own historical data (2022-23 to 2025-26) and vary by jurisdiction. To view the cut-points used for a specific juristdiction, hover over the map.

* Important: Activity levels used in this report were designed to support comparability across jurisdictions and viruses. They may differ from levels reported by provinces and territories, which may use methods tailored to their local surveillance data, epidemiology, and response needs. Differences between federal and provincial/territorial activity levels are expected and should be interpreted in the context of the distinct methodologies and objectives used to assess repiratory virus activity. For details on federal activity levels methodology, see Activity levels methods.

Severe outcomes

Provincial and territorial hospitalizations

Among reporting provinces and territories, some do not provide data on all severe outcomes (hospitalizations, ICU admissions, and deaths) and some do not provide age data. For additional information about the current reporting situation, please refer to the data sources and coverage section in the About this report tab.

Sentinel hospitalizations (pediatrics)

Pediatric (less than 18 years of age) COVID-19, influenza, and RSV-associated severe outcomes data are reported by the Surveillance Program for Rapid Identification and Tracking of Infectious Diseases in kids (SPRINT-KIDS).

Figure 12: Data notes
  • Different provinces and territories may use different testing practices which can affect indicators such as percentage of tests positive. Interpret with caution.
  • Respiratory viruses other than SARS-CoV-2 are only shown at the regional and national levels. Note that some regions do not test for/report on all RVDSS viruses.
