After the French and Indian War, the British gained control of nearly all of North America east of the Mississippi River. This made the British the undisputed colonial power on the continent. They gained control of the Ohio River watershed as well as Canada.
Great Britain lost more over than what they gained from the French and Indian war because whatever land they received from France after the Treaty of Paris (1763) they lost almost all of it. Also, Britain suffered war debt from both the revolutionary war and the French and Indian war.
I really hope this helps!!
