Cal here from Shopify, thanks for reaching out to us. I'd be happy to assist with your currency switch. There are quite a few things to consider when you've already made sales, so please think carefully before making the change.
This feature is locked in the admin if you have already made sales, even a test order. The reason for this is so you can reach out to our support team and chat with us about the effects this will have on your business if you were to change currencies after sales have been made.
Let me know if you still want to go ahead with the currency switch, share your MyShopify URL here, and I'll email the account owner with further information.
Kritesh here from Better Reports team. I believe this is where our app Better Reports can help as well.
We can report sales and transaction for each currency and if given a conversion rate (or a monthly conversion rate), we can report them as a integrated report as well.
In your case, the reporting could all be in USD and we could convert the CAD Sales/Transactions basis given rates.
I encourage you to install Better Reports and start your free 14-day trial and I'll be happy to set this up for you.
Let me know how you go and feel free to reach out if you have any further questions.

Hi @Hoza! I've emailed the account owner with more information on switching currencies.
