Yup. You gotta' call and pay the $27 commish. Then they'll tell you to wait while they root around for a legit quote. Then they'll tell you they need to access another system.
It's best to find a current quote on the TSX and just give Scottrade your limit order- be warned as well: I tried buying these warrants when they showed as trading at .39 each. I had to chase all the way up to .48 to get filled.
Also, keep in mind the currency exchange rate when you place your order.
