Wastewater samples are used to monitor COVID-19 levels in Canada in the absence of widespread laboratory tests in most provinces. Municipal wastewater sampling data is being collected and disseminated nationally to determine COVID-19 outbreaks or the emergence of new options, the Public Health Agency of Canada said.
On Friday, the agency released an easy-to-read online dashboard that shows wastewater monitoring data for several major cities in Canada since the fall of 2020.
The data show that Montreal has some of the lowest concentrations of COVID-19 compared to Vancouver, Toronto, Edmonton, Halifax and Winnipeg.
