OTTAWAFar more sewage has been spilled in Canadian urban centres over the last six years than any other harmful contaminant, newly released figures show.
An analysis by The Canadian Press reveals hundreds of millions of litres of sewage, as well as many other dangerous liquids, have been dumped right under Canadians noses.
This never-before-released information has been kept in a classified government database called NEMISIS. The acronym stands for National Enforcement Management Information System and Intelligence System.

The analysis looked at spills in 18 cities and metropolitan areas across 10 provinces.
They include the metropolitan areas of Toronto, Vancouver and Montreal, and the cities of Calgary, Edmonton, Regina, Saskatoon, Winnipeg, Ottawa, Hamilton, Windsor, Ont., Quebec City, Fredericton, Moncton, N.B., Saint John, N.B., Charlottetown, Halifax and St. Johns, N.L.

Not all BC communities were reviewed in the survey, however the report did highlight how coastal communities are lagging behind inland communities in accepting the impacts of dumping raw sewage into the environment. We have to stop thinking there is no price to be paid for dumping raw sewage into the ocean, says Mae Burrows, Executive Director of the Labour Environmental Alliance (LEAS). Sewage contains toxic chemicals, including PCBs, POPs and PBDEs (fire retardants). With the largest sewage treatment plant in BC the Iona plant in Vancouver only providing primary sewage treatment, these toxic chemicals are contaminating our coastal waters and harming the animals that live there, like the endangered southern resident killer whales and harbour seals.
