Information is here on what you can claim. Be aware that you cannot claim CCA on a lease vehicle. Also, since CRA is quite rabid about employment expense, make sure you have a log to prove your mileage and expenses are business related. If the vehicle is for personal use as well, you need a way to calculate the percentage of business and personal.
