If you need to convert your income or deductions to Canadian dollars, you can get the exchange rates for 2010 and 2011 from the Exchange Rates page of the Bank of Canada Web site. It provides exchange rates for various periods (e.g., daily, monthly, annually).
To get the exchange rates for 2009 and previous years, select a year from the drop-down menu below. You will then be taken to the page on the CRA Web site with the annual Average Exchange Rates page for that year.
