[Talk-ca] Proposed changes to road classification and related stuff

[Jarek Piórkowski]

And I just realized that for Ontario, Statcan's Census Metropolitan Area
designation could be a decent guideline. By my quick count Ontario has 16
CMAs and they seem to cover what I would consider important centres.
Ontario guideline could be that highways leading to CMA centres or
non-urban highways that are NHS should be trunk or motorway, and other
freeways should of course remain motorways too. That's somewhat less
arbitrary than aiming for 20 or 28 centres to connect, or setting a cutoff
at 50k.

To be explicit, I think it is fine that roads like the St. Thomas
Expressway become primary under this guideline. Primary and whatever tag
describes their built form (e.g. expressway=yes) or legal status (e.g.
motorroad=yes) seem a fitting tagging to me.

This might not work for other provinces. Maybe using Statcan's Census
Agglomerations would work for less densely populated provinces?
