Knowledge to Action Series Case Example Ottawa Public Health

Publication Summary

As part of the NCCID and CWN Knowledge to Action series, Ottawa Public Health’s (OPH) approach to wastewater-based surveillance (WBS) stands out as a national model. OPH successfully integrated WBS data into its routine decision-making during the COVID-19 pandemic, providing the public and policymakers with clear, timely, and transparent information on community viral trends. Their collaborative model—working closely with researchers, wastewater utilities, and communications teams—enabled OPH to build public trust and inform risk communication. This case highlights how sustained leadership, cross-sector collaboration, and data storytelling can turn WBS into a powerful tool for local public health response.
