First, this is something that would need to be dealt with by the map creators, not us. However, in my experience, most map renderings show highway=track at some level.
There was actually a recent discussion related to tracks in Canada here. One contributor has a different interpretation of the documentation, but in general forestry roads can be tagged as follows:
-Typical forestry road (wide enough to drive a truck on, but may be unpaved and very rough): highway=track + track_type=[one of the grades]
-Major forestry road (referred to as a “Main” or “Mainline” in BC; generally better maintained, wider, and smoother than the tracks): I generally use highway=unclassified, since that’s the next more major highway type above track.
