[Talk-ca] Revisiting exits with “names” in Ontario and Quebec

[Julian Loke]

Hi List,

https://wiki.openstreetmap.org/wiki/Exit_Info#Canada 

The wiki recommends as best practice the use of "node and way" tagging

Several examples from Canada with accompanying photos of the signage demonstrate the use of
ref= on the node, with destination= and destination:ref= and junction:ref on the way.

Sincerely
Julian Loke
