I had a look at a historical chart about the Canadian and US dollar rates. They've fluctuated a great deal over the past 150 years. There have been a few times when the Canadian government fixed the rate for a period of time, but usually only a few years. 8 years in one case. Then they always decided to let it float again for whatever reason, and the rate would start changing. The Canada dollar has been higher than the US dollar, it's been lower, depends on when. On average over the long haul it's been a little bit lower. It hit rock bottom in 2002. That was when I should've saved all the extra cash that was coming in from the high US $. ;-)

The only prediction that is guaranteed to be right is this one: It's gonna change again.
