The game of football in Canada was derived from the English game of Rugby, but started to diverge from that game in 1874.  A new set of rules was created by McGill University, so you could credit McGill with having invented Canadian Football.  In 1874, McGill played two games against Harvard.  The first game was played under Harvard rules and Harvard won 3-0.  The second game was a 0-0 tie.  Apparently Harvard liked the new rules from McGill enough to introduce them into the Ivy League.
