OK:
Surly LHT: $1,100 U.S. plus tax = $1,437 Canadian Dollars
Norco Kwest mention above = about $1,600 Canadian after paying PST.
So, it's $100 more (Canadian) to buy the Kwest.
However, it's 316 km to Syracuse, where you would have to go to buy LHT. Then you have to return. You have to pay a toll for part of the way. So the cost probably comes out equal.
Plus, it looks to me like the value of the bike is well over the customs limit for a Canadian resident returning to Canada, but I'm just looking at what I can find on the internet.
