<div dir="auto">I just had a look of the GTA at Magic Earth, but the case there is that county/regional roads that were former provincial highways and tagged primary use provincial highway shields. Also another thing is a circle is used for regional/county roads and secondary highways. This is the case for Magic Earth, but what about other renderers? Magic Earth does seems to use a single rendering scheme across Canada that correlates with the underlying OSM classification: shield for motorway, trunk, and primary, and slightly squared-off oblong for secondary. If we should keep using numbers only for ref=*, maybe ask them to improve their render, considering different sign shapes are used across different provinces and the route relation should dictate the sign shape. Most province use a shield for top-level provincial highways (or all highways if there isn't a lower-level network like Alberta 501-986 highways, Manitoba provincial roads and Ontario secondary highways), though others would have it in a different colour (Saskatchewan shields are blue, Quebec green for ordinary provincial highways and red-and-blue Interstate-like style for the autoroutes). An exception exists for Nova Scotia as route numbers there use the "NS [number scheme]", which follows the American way; Magic Earth doesn't render them (so are US state route numbers), but I can point to them how those should be rendered. </div><div dir="auto"><br></div><div dir="auto">By the way, for me, I would insist on adding a prefix (as in the American way) as it will better deal with exceptional cases such as those downloaded provincial highways now marked as county/regional roads, and the proposed reclassifications push for it as it will uncouple (albeit partially) official classification from the OSM classification. That still would need an improvement to renderers though as an adaptation. Also something to address is numbered routes posted in TCH shields (use same scheme as regular provincial highways of [postal abbrev] [number] or use TCH [number]).</div><div dir="auto"><br></div><div dir="auto">Any other renderers that does Canadian highway numbers well aside from the US-centric OSM render?</div><div dir="auto"><br></div><div dir="auto">On Wed, Feb 2, 2022 at 6:33 AM Kevin Farrugia <<a href="mailto:kevinfarrugia@gmail.com">kevinfarrugia@gmail.com</a>> wrote:<br></div><div><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;padding-left:1ex;border-left-color:rgb(204,204,204)"><div dir="ltr"><div>The relations should define the shield (network=*), not a prefix on the ref.

So in the case of some primaries in the GTA that are former provincial highways, not adding a suffix such as CR or RR to distinguish it from provincial highways (this being the likes of the 401, the 407 and the other 400-series highways) would result in a provincial highway shield being rendered instead of a regional or county road shield. Maybe also a consideration for provincial highways that use TCH sign except in Ontario and Quebec.</div><div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Feb 1, 2022 at 9:40 PM Brian M.
