I just found this out when reading about Brazil, the water, and the olympics. The article talked about how Canada is also guilty of dumping raw sewage into the ocean. I checked it out cause I figure it might be something worth knowing in case the opportunity to change it presents itself. It's hard to change things we aren't aware of.

Canada flushes some 200 billion liters of raw sewage directly into natural waterways every year, from the St. Lawrence River to the Strait of Juan de Fuca and the Pacific Ocean. That’s only a fraction of the three trillion liters of sewage Canadians produce annually—about 6 percent, in fact—but it’s still enough to fill more than 40,000 Olympic-sized swimming pools.
According to Macleans, Canada’s leading news magazine, the sewage is a mixture of water, human waste, microorganisms, toxic chemicals, heavy metals, excreted pharmaceuticals and, potentially, pathogens such as cholera, typhoid and hepatitis B.
"It is widely recognized that inadequate or no waste water treatment have negative impact on aquatic life, human uses of water, fisheries and human health,” Environment Canada told Macleans. “Therefore it is unacceptable and shortsighted not to maintain and upgrade infrastructure."
A number of municipalities throughout Canada persist in this practice that the Sierra Legal Defence Fund calls a “national disgrace,” particularly coastal cities where for many years the sewage could be dumped in open water and remain out of sight and out of mind for many people.
Unlike the European Union and the United States, Canada has no national standards for sewage treatment that cities and towns must follow. So while some Canadian cities have top-notch sewage treatment facilities, others have none.
Even Montreal, a seemingly world-class city, pumps 900 billion liters of sewage into the St. Lawrence River. Most of it receives primary treatment, which reduces the number of solids somewhat by means of a settling process, but 3.6 billion liters of that total enters the river as untreated raw sewage.
According to many environmentalists, however, the worst offender in the Canadian landscape is Victoria, the picturesque provincial capital of British Columbia. Not only does Victoria pump its raw sewage directly into the Strait of Juan de Fuca, an arm of the Pacific Ocean, but city officials also claim they are doing the “right and responsible thing” for their community and the environment. They see no reason to change.
