I have no issue with that in any way. I ride scooter style and have never put my bike on a bike path here in Guelph. No matter what a law states Fed/Province, local by law states on all signs " No Motorized ", thus I just stay off and avoid any fuss.
I would hope they make clear that a Mobility Scooter ( 3 or 4 wheel), for handicap use would be able to access paths.
