Canadian Percentage Grades to an American Law School?

MyCousinElleWoods

I go to a school up in Canada for my undergrad, and as some of you may know, Canada grades a bit differently than the US does. A pass is >50 instead of >60, so therefore percentages tend to be lower (an 80 is an A-).
However, I really want to go to a law school down in the states. I know that the LSAC will use the letter grades if they are on your transcript, but my school only puts a conversion in the 'legend' portion of the transcript, and not with the percentages (I don't know if I am being clear here).
Do I have any shot at getting into any American law school? I have heard rumors that schools add an extra 5-10% on Canadian grade percentages because of the difference, but I don't know if that is true or not.
