The US dollar vs Canadian is pretty close to each other, today it is $1.01 vs $1.00 Canadian. Will recheck again next week after the holiday otherwise I would do the exchange today. The good thing, we are not having to exchange for the Euro or British Pound.
Apple Iphone has an APP for "measures". It converts all types of measures including current exchange rates. I compared the rates versus what CNN is showing and they are comparable.
