of 2021, only five FSAs remain unused in British Columbia: V3P, V4H, V4J, V4Y and V8H. Urbanization "Urbanization" is the name Canada Post uses to refer to the process where it replaces a rural postal code (a code with a zero as its second character) with urban postal codes. The vacated rural postal code can then be assigned to another community or retired. Canada Post decides when to urbanize a certain community when its population reaches a certain level, though different factors may also be involved. For example, in early 2008, the postal code G0N 3M0 (covering Sainte-Catherine-de-la-Jacques-Cartier, Fossambault-sur-le-Lac and Lac-Saint-Joseph, Quebec) was urbanized to postal codes beginning with G3N to remove ambiguities and confusions caused by similar street names. Unique among province-wide districts, New Brunswick (postal district E) is completely urbanized, its rural codes having been phased out. Santa Claus In 1974, staff at a Canada Post office in Montreal were noticing a considerable number of letters addressed to Santa Claus entering the postal system, and those letters were being treated as undeliverable. Since employees handling those letters did not want the writers (mostly young children) to be disappointed at the lack of response, they started answering the letters themselves. The amount of mail sent to Santa Claus increased every Christmas, to the point that Canada Post established an official Santa Claus letter-response program in 1983. By 2011, Santa's mail was being handled with the assistance of 11,000 volunteers, mostly current or former postal workers, at multiple locations across Canada devoting an average of twenty-one hours to this seasonal task. Approximately 1,000,000 letters are addressed to Santa Claus each Christmas, including some originating outside Canada, and all of them are answered in the same language in which they are written. Canada Post introduced a special address for mail to Santa Claus, complete with its own postal code: In French, Santa's name translates as "Father Christmas", and mail is addressed to: The postal code H0H 0H0 was chosen for this special seasonal use as it reads "Ho ho ho," if each zero is interpreted as the similar looking letter O. The H0- prefix is an anomaly: the 0 indicates a rural delivery zone, but H is used to designate Montreal, the second-largest city in Canada. As such, the H0- prefix is almost completely empty. H0M, assigned to the international Akwesasne tribal reserve on the Canada–US border, is the only other
