pchencali says: "You will get your 15% tax paid to the Canadian Gov back as tax credit."
That is not necessarily so. It applies only to smaller investors. If your total foreign credits exceed $300 (single filers) or $600 on a joint return, from all foreign sources, you need to file form 1116 which will determine how much of your credits you will receive. I have never received even close to 100% and I am not that big of an investor.
