To qualify as an off-road vehicle (ORV), a vehicle must be “mainly designed or adapted” for use on rough surfaces or unpaved or difficult-to-access terrain. A passenger vehicle temporarily modified for use in these areas cannot be considered an ORV. A motorized mobility aid (AMM) is not a ORV.
The types of vehicles considered to be ORVs, within the meaning of the Act respecting off-highway vehicles, are:
snowmobiles
quad bikes (ATVs or four-wheelers);
utility task vehicles (side-by-side);
all-terrain motorcycles, including motocross bikes;
any other motorized vehicle primarily designed or adapted for use on uneven surfaces or unpaved or difficult-to-access terrain (surfaces consisting of snow, ice, earth, sand or gravel, as well as woodlands and other natural environments).
