If you're going to compare prices, you need to compare them both with or without destination charges.
$53,990 in the US does not include $1200 in destination charges.
$69,990 in Canada includes $1390 in destination charges.
Using your exchange rate with destination charges, the US price is $69,400 in CDN, which is almost the same price as here.
the US price increases makes me feel better about current CAD Model Y pricing. What would make me feel even better would be to see the CAD strengthen in value again to BELOW 1.2 making our price in Canada more competitive VS US.
