Not justifying it, but Victoria has been able to get away with dumping their sewage directly into the Pacific because it is by most standards nothing more than a large town with it's population of only approximately 350,000.
Halifax is the same size but they got around to treating sewage. The difference, I suppose is the nature of the harbour. Halifax harbour is narrow, goes deep inland and ends with a dead end. The tide doesn't completely flush it out and some of it comes back up, each cycle.
