The Trillium Cup is an annual rivalry between the Columbus Crew and Toronto FC. The Trillium Cup is named after the trillium, which is both the official flower of the Canadian province of Ontario, and the official wildflower of the U.S. state of Ohio. The rivalries draw on the team's similarities: two teams are geographically near the Great Lakes that border the United States and Canada and both teams also play in a soccer-specific stadium. The cup is awarded to the team that wins the most points from the series at the season's end. In the event of a draw on points, the first tiebreak is determined by the away goals rule, then by the team with the largest overall goal differential at the conclusion of the match.
