As mnx pointed out on the prototype tour thread, Canadian pricing is due out soon. I've heard that they are indeed working on it.
I'm concerned that Tesla is going to overprice the car. A fellow I know was told they were thinking of averaging the last 5 years exchange rate. But that would be highly biased as it includes the turbulence around the 2008 financial crisis. For the last couple of years the dollar has been within two cents of parity, and we're often above parity. The Canadian buck is now considered a "petrodollar".
I can also point out that Tesla was excessively conservative on the exchange rate for my Roadster. They priced in a possible worsening exchange rate, and it went entirely the other way.
Canadians don't like getting screwed on the exchange rate, and overpricing the Model S could cause a backlash. Surely if the margins on this car are as good as planned they can afford to take a tiny risk on exchange fluctuations.
I'm also wondering how soon the cars will launch here. They said "three months after the US introduction", which makes it early October? I'd sure want to have the car before the snow flies! But I was also noticing that the owner of US Sig Special #114 said on these forums that he was told his delivery would be mid-August. This suggests that the early production rate will be at best 200 cars a month.
