Canada Carrier Calculated Shipping - When!?

Hello, 

Does anyone know when or if Squarespace plans to offer Canada Post to carrier calculated shipping? It is a real pain to go check each province for how much it would cost for weight and box size then to make all of these shipping options for each grouped province. Plus the customer isn't getting the lowest price and shipping can be a big reason someone may not buy. 

Shopify does this easily so I wonder why they haven't bothered to stay up to date with competitors. I really like the SS builder and look of the site but its a huge pain for shipping. 

Thanks!
