Ron,
Unless you can convert the CAD to USD before doing business, I will have to pass. I will suffer a big loss trying to convert the CAD afterwards. The US dollar does not hold up well against the CAD. Sorry.
For my usual trades I can only send funds in your receiving country's currency. I don't mind getting USD and going to a WU location in person to send USD to you but that would require a larger cut or volume for it to be worth my time. PM me if you're interested.
