You need to surround yourself by a team of trusted and very pro efficient professionals(accountant, notary, lawyer), whatever you need for your situation and they will be able to point you to the correct direction.
The Canadian gov. is supposed to lower the corporation taxes to 15% btw. Anyways, like other said, you get a company car, so that expense is on your company. The company could also buy real estate that you rent from it. You put whatever expense you can with the company. You don't pay yourself a salary that is super big because the rule is the bigger your salary, the bigger your taxes are... That way you will pay less tax over the course of time.
Anyways, I'm in no mean a professional so you should seek help offline and not on GFY
