We can submit a change proposal to add them. Probably late for inclusion in STU 3. All we'd need to agree on is the URL for the code system. I'd recommend *not* going the route they followed with the US code system, for a few reasons:
*Canada post defines codes for more than just Canadian provinces & territories
*Websites move around

So my leaning would be http://hl7.org/fhir/CodeSystem/ca-province-and-territory-codes
The code system could then make reference to the CanadaPost website page that's currently source of truth and also enumerate the codes.

It seems the one with the codes for Canadian provinces is missing in FHIR. There is a USPS Two Letter Alphabetic Codes for US states: http://build.fhir.org/valueset-usps-state.html. This value set is also part of a bigger Jurisdiction ValueSet: http://build.fhir.org/valueset-jurisdiction.html. In my opinion, Canadian provinces are supposed to be in included in the Jurisdiction ValueSet, but they are not (jurisdictions from Australia and other countries, other than the US, are missing too).

Hi,

Has anyone assigned or is aware of code system and value set URIs (for use in FHIR) for the Canada Post 2-letter Canadian provinces/territories and US states?

Thanks
Finnie
