As a British official, I realize there are many alternatives to governing Quebec is. I have chosen the policy of isolation to ensure the colony is properly run. By isolating all the colonies, a pro would be there would be less wars and fights over land because we all are own piece of land for our colonies. One big piece of land for the English and their colonies and one big chunk of land is for the French/Acadians, and more for the first nations.
Also, by doing that they might come into alliances and become friends. But one of the cons would be that they would run out of resources and land, so for that they might fight in wars. As I have outlined above, I believe the best policy for governing Quebec is isolation. This will ensure that the colony will remain under British control and provide wealth for our glorious country.
