National Wastewater Monitoring of Pathogens (NWMP): About the dashboard

This dashboard provides data about COVID-19, flu, RSV and mpox virus levels in wastewater.

  • Last updated: 2025-09-19

We’re working with partners as part of a pan-Canadian wastewater monitoring network to track the spread of COVID-19, flu, RSV and mpox (previously called monkeypox). Our partners include municipal, provincial and territorial governments, as well as other federal departments and academia.

The wastewater dashboard allows you to track and compare COVID-19, flu, RSV and mpox levels over time in some communities in Canada.

It also provides a weekly breakdown of COVID-19 variants circulating across Canada. Over time, as the virus grows and spreads, it gains small changes in its genetic material. These changes are mutations that produce new variants of COVID-19.

The data comes from wastewater samples submitted for testing to the National Microbiology Laboratory or participating partner laboratories.

Data for COVID-19, flu, and RSV is presented using weekly (EpiWeek) averages. Data is based on polymerase chain reaction (PCR) testing and adjusted for population served by each sampling site. Genomic data summarizes the COVID-19 variants detected over a recent 10-week period.

Mpox data is presented based on how consistent the wastewater signal is over several weeks of monitoring.

Some communities monitor their own wastewater and publish their own data.

Why we monitor wastewater

The viruses that cause COVID-19, flu, RSV and mpox are shed in wastewater. Even if a person doesn’t have symptoms, they can still shed viruses in their feces, urine or while brushing their teeth. The viruses can then be detected by testing the community’s wastewater. Wastewater monitoring only detects the viruses in a community or institution. It can’t identify single cases or households.

By monitoring wastewater we can:

Wastewater monitoring can provide an early warning of viruses in a community or high-risk setting. This supports an early public health response, which may include reminding the public about personal protective measures.

Wastewater monitoring partners

We thank participating municipalities for submitting wastewater samples and associated data. We also thank federal, provincial and territorial public health professionals for valued input on the development of this program, as well as the many scientists supporting wastewater monitoring networks nationally.

Canadian Wastewater Survey (CWS)

The Public Health Agency of Canada has been partnering with Statistics Canada on the Canadian Wastewater Survey (CWS) since September 2020 to conduct wastewater monitoring in Halifax, Montréal, Toronto, Edmonton and Metro Vancouver.

We continue to work with provinces and territories to provide federal leadership, connect data across the country, and share best practices on emerging science. In 2024, the following cities and regions were added to the joint collection program: Calgary (AB), Kingston (ON), London (ON), Moncton (NB), Peel Region (ON), Sudbury (ON), and Victoria (BC). This strengthens Canada’s preparedness for disease outbreaks and our ability to inform the public about potential risks in these communities. Data from these locations will be added to the dashboard as it becomes available.
