Oshawa
13 postal areas in Ontario
What this page is
Every forward sortation area whose residents mostly live inside the Oshawa census metropolitan area. Each one has its own profile with census figures, crime, rent, amenity access and air quality.
These areas do not tile the city. A postal area is listed here when more of its residents live inside Oshawa than in any other metropolitan area — so the city extends beyond some of them, and parts of some of them fall outside it. There is no combined figure on this page for that reason; the numbers live on the area pages, where each one carries the geography it describes.
