I have Google.com/ig as my homepage, and the Currency Converter is a plug-in that I chose from the list of "gadgets" that Google offers. So it's not technically Google's converter, but it says $2 for Canada.
And I've been using it for a year. So it's wrong, not me.
Also, I'd recommend
http://www.xe.com for a currency converter. It says it's $1.00255.
But I do apologize for the mis-information.
