The only full-on canopy tour I've ever done, was near Ochi. I don't remember the name of the place as it was arranged by the hotel, but it was a nice lengthy tour with a good number of zip lines. This was probably 10+ years ago.

YS Falls only has a couple lines, but it is a nice diversion if you are going for the falls. I would imagine that Jam West has more lines in their course, but I think you are right about the lack of canopy.
