Why was the land gained from Great Britain in the Treaty of Paris a cause for trouble and what steps helped to solve it?

The Treaty of Paris, signed in 1763, brought an end to the Seven Years' War fought between France and Great Britain. France gave up all of its territorial holdings in North America, transferring a number of these to Great Britain. Canada, a number of islands in the Caribbean and the area between the Mississippi River and the Appalachian Mountains all fell under British control as a result of the treaty.
