Yes, the list of eligible vehicles is available on Transport Canada's website. The incentive can be up to $5,000. Quebec has an incentive of up to $8,000. As you mentioned, the City of Laval is unique in that it also provides a $2,000 incentive. All those incentives can be combined, but the vehicle the person is buying must be on all three lists. It might appear on one list, but not on the others. If the vehicle appears on all three lists, which include the most common vehicles, the person can benefit from a truly significant discount.
