How did the the treaty of Paris in 1765 hangar the map of north America?

The Treaty of Paris in 1763, which ended the French and Indian War, significantly altered the map of North America by transferring vast territories from France to Britain. France ceded Canada and all its territories east of the Mississippi River to Britain, while Spain, an ally of France, ceded Florida to Britain in exchange for the return of Havana, Cuba. This treaty effectively eliminated French colonial presence on the continent, consolidating British control over a large portion of North America and setting the stage for future conflicts between British settlers and Indigenous peoples.
