n. — Administration
a postal facility serving a heavily populated area that may be far from the nearest post office, often in urban areas.
In the US, the term is synonymous with post office and in Canada, many use this technical term in a similar way. Canada was not the first nation to use the term postal station, although the precise meaning of a kind of sub post office that does not offer any services to customers but is needed for postal delivery in densely populated areas, may be. Currently, postal station is most prevalent in Canada according to internet domain searches (see Chart 1), yet not sufficiently more frequent to declare it a Canadianism. Likewise, the semantic distinction seems to be too narrow and technical to consider it one of the six types of Canadianisms (see Dollinger 2015c).

- 1977  About 2,600 letter carriers serve the area covered by the South Central mail sorting plant, which accounts for 30 per cent of all the mail moved in Canada. Edward Roworth, spokesman for the Post Office, said the Post Office had been on the verge of telling the 2,600 letter carriers in the area that is bounded by Victoria Park Avenue, the Humber River, Highway 401 and the Lakeshore, not to report to work today. However, the movement of mail out of the South Central plant made it possible to reverse that tentative decision.
Mail is distributed from the South Central plant to 28 postal stations, where it is taken over by the letter carriers. The renewal of the discussions dealing with the indefinite suspension of the nine employees began at 6 p.m. after Gordon Cunningham, the Metro area director for the Post Office, returned from Ottawa where he consulted his superiors.

Recently, Canada Post announced that supermailboxes would serve more than 4,000 points of delivery in Richmond Hill before summer.
