One thing Americans and Canadians can agree on is that we don't want each other's health care systems. In truth, most Americans don't know how Canada's system works and Canadians don't know much about the U.S. system. Yes, there are waiting lists for some services -- but, no, Canadians are not coming across the border in droves to get American care. Separating fact from opinion as the Canadian ambassador long ago urged was something I tried to do as I made my way across Canada while visiting there recently. In some ways, the Canadian system is very different from U.S. health care. In other ways, it's very much the same and faces similar challenges in the years ahead.
