The issues is they are artificially cheap, which undercuts Canada's auto component industry from serving as an EV hub.
The Chinese government paid for production and have lots (as in sites) of cars that are unsold. They offered huge discounts to unload last years production. Since there were laws about discounting new cars, they moved them (paperwork wise) through shell type arrangements to make them appear as used cars (with less than 5km on the odometer etc).

That stuff undercuts any means of US and Canada EVs being viable.
