Answer:
As a result of the Treaty of Paris in 1763, the British colonial power gained vast amounts of land in North America. The treaty was signed at the end of the Seven Years' War, which was a global conflict that involved a number of European powers, as well as their respective colonies in North America and elsewhere. The Treaty of Paris officially ended the war and marked the end of France's involvement in North America. As a result of the treaty, France ceded control of all of its territories in North America, including New France (present-day Canada), to the British. In addition, Spain ceded control of Florida to the British. The treaty significantly expanded the size of the British North American colonies and established the British as the dominant colonial power in the region.
