Where can I find exchange rates from the past?

I have to reimburse a double payment that was made to me about a year and a half ago in Canadian currency and then, of course, in my bank account, became American currency. I'm seeing sites which have today's rates but not finding the past. I'd appreciate any leads. Thank you.
