I don't see why not. Like I said, I haven't bought yet but I'm pretty sure Etrade will accept my buy order. You'll want to check the bid and ask on the TSX before you bid. There's a link in the Railpower homepage to the TSX. Another place to find a quote is at http://www.stockhouse.com Use the symbol "P", here's a better link.... http://www.stockhouse.com/comp_info.asp?symbol=P&table=LIST
Stockhouse has a currency converter on the quote page.
