I keep getting this message in my checkout “Shipping not available”. I only want to ship through out Canada which I already have set up. I have checked and all my inventory is set up for one location. Under SHIPPING ORGINS it is set as Canada all provinces and under carrier names it has this:

Canada Post (Discounted rates from Shopify Shipping)

but doesn’t show any rates at all. I have 3 services set up. Not sure how to fix this.

Thanks
