Toronto FC had one of the greatest seasons in MLS history in 2017, becoming just the second team ever to win the domestic Treble. They captured the Supporters' Shield with a record-breaking 69 points, won MLS Cup 2017 by defeating the Seattle Sounders 2-0, and also claimed the Canadian Championship.
The team set multiple MLS records that season, including most points in a regular season (69), most wins (20), best goal difference (+48), and most goals scored at home (40). Led by Sebastian Giovinco, Jozy Altidore, and Michael Bradley, TFC finished the regular season with a 20-7-7 record and only lost twice at BMO Field all year.
Toronto FC's 2017 campaign is widely considered one of the most dominant seasons by any team in MLS history, cementing their place among the league's all-time great teams and marking the franchise's first MLS Cup title after years of playoff disappointments.
