> I agree with the proposal. It makes it easier to identify which routes are provincially-owned, which are regional/county roads, and which ones are municipal. For example, with the current no-prefix tagging, one would have no idea that York Regional Road 7 in Markham becomes Ontario Highway 7 east of Reesor Road, and a person would have to look online to websites such as <a href="https://thekingshighway.ca/" rel="noreferrer noreferrer" target="_blank">https://thekingshighway.ca/</a> in order to accurately determine where the provincial part of the highway starts.<br>
<br>
Actually we have this data in OSM, in machine-readable `network` tags<br>
in route relations. York's Highway 7 is<br>
<a href="https://osm.org/relation/4426016" rel="noreferrer noreferrer" target="_blank">https://osm.org/relation/4426016</a> with network=CA:ON:York while the<br>
provincial part is <a href="https://osm.org/relation/2203858" rel="noreferrer noreferrer" target="_blank">https://osm.org/relation/2203858</a> with<br>
network=CA:ON:primary.<br>
<br>
(Incidentally, the `network` tag also allows OSM users to distinguish<br>
between municipal and provincial freeways, for example QEW as<br>
CA:ON:primary <a href="https://osm.org/relation/102331" rel="noreferrer noreferrer" target="_blank">https://osm.org/relation/102331</a> vs Gardiner as<br>
CA:ON:Toronto:Expressway <a href="https://osm.org/relation/109578" rel="noreferrer noreferrer" target="_blank">https://osm.org/relation/109578</a>.)<br>
<br>
It is true that this is not rendered on the default <a href="http://openstreetmap.org" rel="noreferrer noreferrer" target="_blank">openstreetmap.org</a><br>
map layer, but changing tags to get rendering on any one renderer is<br>
generally discouraged in OSM. On the flip side, this `network` tag<br>
actually contains more information than an "RR" in ref would have -<br>
for example, a specialized renderer could show shields for York<br>
(<a href="https://en.wikipedia.org/wiki/File:York_Regional_Road_7.svg" rel="noreferrer noreferrer" target="_blank">https://en.wikipedia.org/wiki/File:York_Regional_Road_7.svg</a>)<br>
differently from shields for Niagara (network=CA:ON:Niagara resulting<br>
in a shield like<br>
<a href="https://en.wikipedia.org/wiki/File:Niagara_Regional_Road_20.svg" rel="noreferrer noreferrer" target="_blank">https://en.wikipedia.org/wiki/File:Niagara_Regional_Road_20.svg</a>)<br>
<br>
> As for the prefix not being on the signs, US Route signs also do not have US- prefix on their shields, nor do many state route shields either. So I don't understand the argument there.<br>
<br>
There is a counter argument that perhaps routes in the USA shouldn't<br>
have prefixes either - since they're not signed, and, you know, for<br>
consistency with Canada ;)<br>
<br>
> To answer the one about Hamilton: I know that Sudbury refers to theirs as "Municipal Road X", so perhaps that would be the same with Hamilton?<br>
<br>
Actually most numbered routes in Hamilton follow named roads (like<br>
King Street, Main Street), and where they don't, the road is often<br>
still named like simply "Highway 8". For an example, check out route<br>
65 near their southern border <a href="https://osm.org/relation/4137034" rel="noreferrer noreferrer" target="_blank">https://osm.org/relation/4137034</a> (the<br>
history of that relation might also be interesting for those wanting<br>
to find an abbreviation for Hamilton roads, but you'll probably want<br>
to find a verifiable source).<br>
<br>
As another example, Oxford County in Ontario is legally a regional<br>
municipality, should their roads be prefixed CR or RR? Who can verify<br>
all of these?<br>
