I suppose you realize the people running those manufacturing companies won't be hurt much at all, everyone who scrapes by trying to making a living work for them will hurt a lot when they get fired.
This is these companies own fault. These companies have grown cozy rent seeking with little competition and have completely missed the electrification of cars as a result. Cheaper cars will hurt those workers, but all of society will be better off when one of their largest expenses decreases.
Keep doing you, Canada.
