Canada Sales TAX invoice based on buyer's province

I am new to Dolibarr any help would be greatly appreciated. I’ve seen similar threads and can’t find any answers to this basic question.
We would like to use Dolibarr to generate invoices for customer orders.
I have setup the tax rules under setup dictonaries.
When setting up an invoice I would like the correct sales tax amount to be auto applied to each product line item based on the buyer’s province. Sales tax differs by province in Canada. By default it is leaving each line’s sales tax field blank.
Thanks for any help
