Down here south of the border, we recently launched the
openstreetmap-americana project, and we're the first open source map that
has highway shields with full concurrency support on vector tiles. We do
not use the highway classification to determine which shield is used.  We
derive this information entirely from the list of road route relations that
a way is a member of, as well as the network and ref tag on that route
relation.  We ignore the ref tag on ways entirely for the purpose of
generating shields.

(no, we haven't implemented Canada highway shields yet.  Yes, we want to)
