You can definitely split up the provinces into different shipping zones for Canada. This can be accomplished by removing the provinces (i.e. Ontario and Quebec) from the overall Canada shipping zone by clicking "Edit" -> then creating new shipping zones for them, each with their own shipping rates. For example, if you take a look at this screenshot, this is what I have created.
I hope this helps and have a lovely weekend!
I hope this guide gives you a very clear understanding of Zones and Provinces: Setting up Shipping zones. The guide explains how to set up the zones and add zones based on postcodes.
