I don't think tesla will do much fighting on this one unfortunately for a few reasons.
1. They get paid full price no matter what, the rebate goes to you not them (unlike most dealerships who typically apply on your behalf and take the amount off at time of sale).
2. They will easily still sell the car to someone else, either in Quebec, BC, or US (as well as those of us still willing to accept the car without the rebate). So again, are unlikely to be out of pocket anything here .
3. Even if they fought something, it's highly unlikely that public opinion on this one will be swayed in the next 2 months (sorry...I'm a realist :/ )
A few weeks ago when things were looking to go south I spent a few nights soul searching how much I wanted the car and decided rebate or no I would proceed....if nothing else anyone keeping their order has to be at peace with the fact that they likely won't receive the rebate.
On a plus side, that likely means resale value will be that much higher a number of years down the road (now that's me being a glass half full guy
)
