Can say the same for the US, but would better leave it to the guys south of the border.

>> I think this might at least partially be a StreetComplete issue. For example https://www.openstreetmap.org/changeset/158937395 added maxspeed:type=CA:urban in November 2024, or https://www.openstreetmap.org/changeset/154714996 added CA:rural in August 2024. Anyone want to check on StreetComplete's code and Github issues?
>> 
>> There are also some old cases of StreetComplete users adding CA:rural on city streets like https://www.openstreetmap.org/changeset/60230633 in 2018, which I think can be removed on sight as clearly wrong?

Given traffic laws in Canada are a provincial and territorial matter, I have considered its usage questionable. Province-specific values, prefixed with CA-(province/territory name abbreviation) such as CA-ON:urban for an implied 50 km/h urban speed limit in Ontario better reflect the nature of Canadian traffic laws, but so far, their usage is dwarfed by the CA:-prefixed values.

>> 
>> The table in https://en.wikipedia.org/wiki/Speed_limits_in_Canada looks a mess, I don't know if StreetComplete wants to add all these categories. There's also a quite long disclaimer in https://wiki.openstreetmap.org/wiki/Key:maxspeed:type#Canada for `CA:urban`.
>> 
>> Personally I think StreetComplete should be setting maxspeed:type in Canada as only `sign` and `CA-XX:urban` (as the rural limits vary too much depending on type of road) and even that should exclude some provinces (e.g. Saskatchewan apparently doesn't have a backstop urban limit if not posted?).
