Setting your shipping destination to Default to customer shipping address should still return the shipping options for CA correctly. Did you test with a CA shipping address when this option is selected?

If you don’t see the shipping options when having this option enabled, it looks like it could be a conflict on your site that prevents the options from showing up. I’d suggest looking into doing a conflict test to help you find out the culprit. Here’s the documentation on conflict testing: https://docs.woocommerce.com/document/how-to-test-for-conflicts/

I hope you found the previous reply helpful. We haven’t heard back from you in a while, so I’m going to mark this as resolved – if you have any further questions, you can start a new thread.
