Hi John,

If we want to be able generate mailing addresses from OSM (is that a valid use case?), then whatever the city address Canada Post thinks we are in needs to be tagged in some fashion.   Google maps and Bing maps both think I'm in "Kanata".  OSM thinks I'm in "Kanata North". Both are correct, in different ways.

If I we want to do reverse geo coding using OSM data, then the mailing address should be represented in some fashion because that's what people expect to see.

https://wiki.openstreetmap.org/wiki/Key:addr says about addr:city: /May not be required if boundary=administrative <https://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative> is used correctly. May or may not be a clone of is_in:city <https://wiki.openstreetmap.org/wiki/Key:is_in:city>=* (in some places the city in the address corresponds to the post office that serves the area rather than the actual city, if any, in which the building is located)! The name of the city as given in *postal addresses* of the building/area. /(emphasis added)

BTW, this is one of the reasons I started all these discussions about  aligning Canada OSM data... I was trying to use OSM to build a map for a community group and rather than just doing post-cleanup work on the map data in my own private copy, I thought it might be better to see what data we could align and make useful for everyone.  I'll only take it as far as consensus is achieved.

So what we are saying is the city field should be filled in not with the physical city but with Canada Posts thoughts of the day?

Orleans is different.  It never was a municipality.

    Hi John,

    I live in Kanata.  If I type my "<number> <street> Ottawa" into
    the Canada Post lookup tool
    it helpfully corrects me to "Kanata".   Same for old "City of
    Nepean" addresses.   Try "1000 Palladium Drive, Kanata, ON"
    (Canadian Tire Center).

    As far as I know, within the City of Ottawa, everyone's postal
    address uses the pre-amalgamted city names while the city hasn't
    yet finished de-duplicating street names.   So addr:city should
    probably be filled in accordingly.

    I seem to recall from talking to Canada Post that Orleans is
    the only location for which that is true.  All of Orleans is
    located within Ottawa. So how do you tag it?  It is within the
    City of Ottawa these days.

    Thanks John

        Hi Clifford,

        (It was good to meet you at SOTM US last year).

        Thanks for your comments... The situation with addr:city
        appears to me to be more complex than the situation with
        addr:province/addr:country, along the lines of what you are
        mentioning. My personal home mailing address cannot be
        resolved in OSM because the mailing address does not match
        any of the boundaries.  (OSM boundaries are correct, but
        the official post address cannot be resolved from the
        boundaries). So I have a feeling that addr:city is going to
        be required, at least in some cases.

        Do you have a view on addr:province/addr:state or
        addr:country? US/Canada probably have more similarities
        than differences, so your input is very welcome.
