Ontario Bill 126, changes to the Road Safety Act 2009, came into effect a few weeks ago.
(7) Subsection 1 (1) of the Act is amended by adding the following definition:
"power-assisted bicycle" means a bicycle that,
(a) is a power-assisted bicycle as defined in subsection 2 (1) of the Motor Vehicle Safety Regulations made under the Motor Vehicle Safety Act (Canada),
(b) bears a label affixed by the manufacturer in compliance with the definition referred to in clause (a),
(c) has affixed to it pedals that are operable, and
(d) is capable of being propelled solely by muscular power; ("bicyclette assistée")
There is NO label on my BionX system and the dealer who I purchased it from is not aware of the existence of any such label.
Hopefully the police have better things to do with their time than hassle E Bike users over technicalities like this but I wouldn't bet money on it.
