Backflow Compliance in Ottawa

Ottawa's role as Canada's national capital means a substantial portion of its commercial real estate is occupied by federal government departments, Crown corporations, embassies, and national institutions — all of which require cross-connection control under the City of Ottawa Water By-Law. The Ottawa Hospital Civic and General campuses, Carleton University and the University of Ottawa, the ByWard Market hospitality cluster, and the dense parliamentary precinct each present distinct backflow compliance profiles. City of Ottawa Water Services enforces By-Law No. 2018-102 with annual compliance cycles, and certified testers are required to submit results directly through the City's reporting process.
