User:Jarek Piórkowski/Canadian addresses

Collecting in data to question what exactly should go in addr:*=* tags:

City / community names

Canada Post address lookup (official postal addresses) still uses pre-amalgamation cities in Toronto (amalgamated 1998) and Ottawa (amalgamated 2001)

(This is one solution, though IMO a poor one, to duplicate street names in Toronto, e.g. King Street and Church Street in Weston vs downtown)

(TODO: what is the situation in Montreal?)

Varying abbreviation / spelling of community names - see writeup in https://ruk.ca/content/st-peters-vs-st-peters, table copied below:

Rule making body	Community name
The Community	St. Peter’s Bay
Government of Prince Edward Island	St. Peters Bay
PEI Civic Addressing System	St Peters
Government of Canada	St. Peters Bay
Canada Post	St-Peters Bay (possibly changed to ST. PETERS BAY since 2016?)

Street names

Varying abbreviation / spelling of street names - see https://www.openstreetmap.org/note/1733741, with forms including "St Helens Avenue" (Geobase, City name sign, City street name index), "St. Helen's Av." (another City name sign), and "SAINT HELENS AVE" (Canada Post)

If "St" is saint, which saint is "St. Clarens Avenue" named after?

Is there any justified case for name of highway=* being different than name of adjacent addr:street=*?

Address formats

TODO: RR addresses in rural areas - are these used for anything other than mail delivery? How are courier packages delivered? What do the property tax bills say?

What is not ambiguous

Postal codes (but these are not open data)
