Whale Tail, you are making a very common mistake here when it comes to calculating currency exchange. Many people think this way - "oh, it costs $1.20cdn to buy a us $ so the rate is 80 cents, if it's $1.37 it's 63 cents, etc" where they simply subtract the extra amount from $1.00 and call it the rate.

The proper conversion is to DIVIDE us/cdn as in $1.00/$1.37 = .7299 or 73 cents, $1.00/1.20 = .8333 or 83 cents, etc. If you still are unsure, remember that math ALWAYS works both ways. The reverse is to MULTIPLY cdn x us. So at a 73 cent dollar, it takes $1.37 cdn to = $1 us
( $1.37 x .73 = $1.00)

So while the exchange rate is getting worse for us Canuks, it's not quite a bad as you think (thank goodness!)
