I'm in Richmond Hill and the quoted shipping costs including PST/GST/duties/brokerage were:
$318 (no turbo)
$424 (with turbo)
Now remember, the HO is also $200 more than the MK3 so there is another $30 or so in taxes alone.
Not sure why Thornhill would be different than TO, unless the depot for Fedex is much closer to where you are.
Regardless of the fact that it's pretty expensive to ship these to Canada, it's nice to see HSU giving us a "landed cost" versus some ID companies where you have no idea what the duties/brokerage fees will be until it shows up at your door!
