in the region is affected by the raw sewage dumping that Victoria engages in. Like Victoria, Vancouver is part of a province, British Columbia, that has had lax regulation on sewage treatment and, as noted in the other post, Vancouver has its own problems in that area.
I disagree with you that any large city that dumps sewage after only going through a primary treatment can be considered to have an excellent environmental record.

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.
