The COVID-19 Wastewater Coalition has developed two maps that can help us understand where wastewater-based epidemiology is already underway and/or being applied in Canada.

Over the past year, researchers around the globe have been testing wastewater for the presence of COVID-19 infection in a number of communities. Work is now underway in more than 50 countries at over 2000 sites, as captured by COVIDPoops19.

Researchers in Canada are monitoring SARS-CoV-2 (and variants of the virus) in community wastewater samples to increase our understanding of community spread during the third wave and as vaccinations increase.

The COVID-19 Wastewater Coalition has developed two maps that can serve as a stepping stone in building a more detailed national picture:

Map #1: Wastewater sampling and analysis of SARS-CoV-2 in Canada 

Map #2: Canadian Labs conducting wastewater analysis for SARS-CoV-2

The Coalition maps provide a snapshot from early May 2021 of the Canadian Water Network’s knowledge about where publicly disclosed work is ongoing. To help further stimulate discussion about the potential merits and uses of the data, the maps include some subjective determinations by CWN as to the nature of the work relative to its role in public health decision-making.
