Does it make sense to have a GMB for every location?

Currently our business operates in 1 province and 11 cities. We are expanding to a 2nd province and 4 more cities. I have only one GMB page in our current city with the 11 cities added as service locations. Does it make more sense to: -create a new page for new province add cities as service locations? -add the the province and cities to current page? -Create a page for every single city? Also is it okay to add province to business name to differentiate on google?
