The build in tax for PS3 is setup in the admin, it will charge the rate specified based on the state or province you enter. You could use this default tax for your Quebec provincial tax by setting the rate and the state to QC.
For the other tax rules you would need eCart to implement them. With eCart installed in your DW environment you could add in two new tax rules based on the users shipping country. If you have access to this tool and would like some more guidance on implementing the tax rules post back with any specific questions that you have and we will be glad to help you with what we can.
