Global Payment Service receiving accounts in CAD

Hi,
I need a Global Payment Service receiving accounts in CAD but I don't have an option to apply. I have GPS accounts in other currencies (USD , EUR, GDP) but not in CAD.
I've created 3 separate cases with the customer service for which I got a automated reply saying how to apply for Global Payment Service account.
The problem is that I don't have an option of CAD account.
Please help.
