Who's On First postal code data for the Canada (CA).
As of this writing most but not all postal codes have geometries. That said only about 1,600 records have Polygon geometries. The remaining (~800K) postal codes have all been assigned an approximate geometry, specifically the centroid for their containing FSA.
For example the geometry for the postal code T6R 2R3 will be the centroid for the postal code T6R. Additionally these records (with derived coordinates) will contain a mz:is_approximate=1 property.
This work is still in the early stages and some important ancillary artifacts normally found in Who's On First data repositories (like meta files) have not been created yet.
