The US dollar and Canadian Dollar share the same currency symbol $, which is confusing.
The Canadian dollar is an option in the Currency Switcher. When is selected as currency I want the product prices to show CAD$ for Canadian dollar and USD$ for the US dollar and AUD$ for the Australian dollar. The WooCommerce Multilingula & Multicurrency configuration doesn't seem to have that option, which is odd
Sorry for the delayed response - there has been a full ticket queue in the past few days and there has also been a weekend where not so many of us, supporters, are working.
I also wanted to take the proper time to make sure that I came back to you with an accurate answer, so I double-checked with some of my colleagues, too.
This will require custom code so it will fall out of the purpose of our Support Policy but I still wanted to take the time to point you in the right direction.
I hope that you will find this information helpful. 🙂
