How can I capture a CAD currency

[durck0001]

I want to charge cad currency and use "cad" as currency code,

but got error 

Error message: The supplied currency code is either invalid, not supported, not allowed for this merchant or doesnt have an exchange rate.

Anybody helps?

Your account is set up with a single currency. To process in CAD check with whomever set up your account as you would need a new one to process CAD.
