Greater Victoria is the last coastal region in Canada to stop dumping raw sewage into the ocean.
Or maybe not:
The Canadian Press provided a useful breakdown of statistics on the country’s sewage situation:
215 billion liters: Reported amount of untreated sewage flowing into Canadian waterways in 2017.
1.02 trillion liters: Reported amount of untreated sewage flowing out between 2013 and 2017.
269: Number of municipal water systems that are supposed to report sewage outflows to Environment Canada each year.
159: Number of municipal water systems that actually reported sewage outflows to Environment Canada each year.
1: Number of municipalities known to monitor the actual amount of sewage outflows versus a calculated estimate.
36 percent: Share of total leaks and spills in 2018 that came from British Columbia.
Nearly 120 million cubic metres of untreated sewage and runoff entered Canadian waterways in 2016...
In combined sewer systems, the pipes that carry rainwater runoff also carry sewage from homes and businesses to the treatment plant. During heavy rains, these pipes can end up carrying more wastewater than the plant can handle, so they have overflow points where the wastewater can pour directly into a waterway, like a river or lake.
British Columbia was responsible for almost 40 per cent of the sewage overflows across the country in 2016.
Data provided by Environment Canada shows B.C. was responsible for the highest volume of sewage overflows across the country in 2016, and that doesn’t include the untreated sewage released on purpose in cities like Victoria, which doesn’t yet have a sewage treatment plant.
Nova Scotia, the second-worst offender, released more than 19 million cubic metres of sewage and runoff in 2016.
Quebec City to dump 46 million litres of sewage waste into St. Lawrence River
February 22, 2018
Quebec City is warning residents it will be dumping 46 million litres of untreated wastewater into the St. Lawrence River over a 12-hour period starting Thursday night at 11 p.m.
The city is asking residents to limit water consumption during the operation, which is expected to end at 11 a.m. on Friday.
...sewage will be dumped directly into the St. Lawrence, "although there is a grid in place which retains solids,"
Maintenance work is required on the Saint-Pascal pumping station, which entails emptying it entirely to allow workers inside.
...not doing the repairs could damage the structure of the station, which was last emptied in November 2016, when 135 million litres of untreated water were washed into the St. Lawrence River.
At the time... the procedure was fairly common, although the controversy over Montreal's flushgate episode in 2015 has forced the city to be more transparent.
Montreal dumped some 4.9 billion litres of untreated wastewater into the St. Lawrence in November of that year.
Scientists with the city of Montreal later found the water quality of the St. Lawrence River returned to normal four to 10 days after the dump ended.

Anyway, nothing has changed. Same arguments and counter-arguments as back in the 1960s, and untreated wastewater continues to pour into the oceans regardless. But we've certainly made some major strides with the politics and the PR aspects.
