biotplaya.... re Choice. I'm not sure if you can buy it in Canada thru Schwab. You would have to call them. I couldn't thru Ameritrade so went to Interactive Brokers.
I did buy all my Choice thru the pink sheet route so I am holding the pink sheet version. Since December, I have been buying the Canadian versions of all stocks that I could but bought all the Canadian juniors for medium term holds so didn't expect to trade them.
