Currency display on the front end -Canadian dollars

Hi

I have a client who takes Canadian dollars (her stripe is in CAD), all the currency on the back end is in CAD but on the front end it just displays $XX instead of CAD$XX. Where can I change this to display the currency in CAD on the front end (attached image) or if the customer is in US display US$XX?

I have set the Language and region to Canada English

Thanks

Femy
