4. For the purposes of this Regulation, the vehicle fleet of a vehicle manufacturer means all the vehicles, of whatever make, marketed in Québec by that vehicle manufacturer.
If a vehicle manufacturer markets in Québec, under one of its trademarks, vehicles from another manufacturer, the vehicles from the other manufacturer are then part of the vehicle fleet of the first manufacturer.
Vehicles manufactured by more than one vehicle manufacturer and marketed in Québec constitute a single vehicle fleet(a) where at least 10% of the property of a vehicle manufacturer is held by another vehicle manufacturer; or
(b) where at least 10% of the capital of each vehicle manufacturer is held by the same third party.
