This dashboard provides trend data about the levels of COVID-19 in the wastewater (sewage) of different communities and settings across Canada. This can reflect the levels of COVID-19 in those communities. We update this information on Tuesdays and Fridays at 12:00 noon Eastern Time. In the event of a holiday, we update on the next business day. Data may lag slightly, due to the time it takes to transport and analyze the samples.
