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

[Jherome Miguel]

On Magic Earth, the case is the shield rendered seem to depend on the
underlying classification (other renderers too?). 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.
