In Ontario it's illegal to operate any motorized scooter, whether stand up or sit down, on the sidewalk unless your handicapped. They have bike lanes there in a lot of cities though as well. I personally think they shouldn't be on the sidewalks as we already have enough BS with cyclists on the sidewalks. At some point pedestrians' rights have to matter for something.
