Excerpts from Books and Wikipedia
"British naval victories in the American War of Independence after Cornwallis's surrender gave them a stronger hand in the peace negotiations, but the British had had enough. . . . Congress had appointed Benjamin Franklin, who was respected in both London and Paris, as the principal American representative in the negotiations. . . . In the treaty signed on September 3, 1783, in Paris, American independence was recognized and the boundaries of the United States wee agreed to stretch from the Atlantic to the Mississippi, but Britain kept Canada."
