Does Tesla do business differently in Canada than the U.S.? I thought purchasing in the U.S. was done through an app, and everything was one-price, no negotiation? Pick the options you want, and the car is delivered to your door at sometime in the future. And the showrooms were exactly that, places to show the car, no selling, no salesmen, no protection plan upselling, undercoatings, etc.. Maybe someone who has purchased a Tesla in Canada or the U.S. could chime in?
