We have the same law here in Ontario, Canada as well. Technically, we are not even supposed to stand up on the pegs while operating a motorycle on the street. Ontario Regulation 455/07, pursuant to the Highway Traffic Act, defines "engaging in a stunt" as a number of activities, including, "driving a motor vehicle in a manner that indicates an intention to lift some or all of its tires from the surface of the highway, including driving a motorcycle with only one wheel in contact with the ground, but not including the use of lift axles on commercial motor vehicles," and "driving a motor vehicle while the driver is not sitting in the driver’s seat."
Welcome to Ontario, the land that fun forgot.
