It's that time of the year again, tax time.

January 2012 Update: Here's a link to the rates for 2011 (ie: the rates you will probably use for your tax return due April 30th 2012)

For those looking for the average annual exchange rate for the Canadian dollar and other currencies for 2010, here they are unofficially.
IE: If you're filling out a tax return and filing it for the CRA's April 30th 2011 deadline for personal tax returns. .

Please contact your accountant or other financial professional as to when you should be using these exchange rates (sometimes you shouldn't be using the average rates here).

These rates are straight from the horse's mouth: The Bank of Canada, which the CRA advises you to use. I merely copy and pasted their rates here.

Please be absolutely sure that you are calculating the resultant Canadian dollars the right way. For example, the Canadian dollar is worth substantially more than a Vietnamese dong, and slightly less than a US$, on average, for the Year 2010.  A handy place to lookup spot exchange rates is xe.net.
