Fair point R_D...nothing is without risk. Having said that, I personally feel that interest rates have a long time to go before they double. I might also suggest that the recent hikes by the BoC are meant to reign in personal borrowing, not defend the dollar or cool an apparently robust economy such as in the U.S. I have read/heard many thoughtful (but not infallible) commentators positing a "new normal" for borrowing/savings rates going forward. We shall see. My point here is to display a tool that, under the right circumstances, can be an effective retirement option.
