wirmpolter, the cost to import a foreign car from the USA to canada is:
6.1% duty
+ excise tax if it has air conditioning (i think it's $100)
+ excise tax if it is a heavy vehicle (over 2000kg)
+ 7.0% GST
+ 8.0% PST(ontario)
so it's basically 21%.

RTPscoupe, like RedAGT mentioned, the impression i get is that, if the car is over 15 years old, you can import it, even if it wasn't manufactured to meet US or canadian standards. this surprises me, but i guess the attitude is the same that applies to emissions testing, that is, if the car is real old, there's so few of them, the govt doesn't care about them. BTW the newspaper today says the ontario govt is going to phase out emissions testing.
edit: don't know the details about the newer skylines. i'd guess they're illegal in the USA and canada . but once they're 15 years old, they can be imported into canada.
