Greg Vanney was named the ninth head coach in club history on August 31, 2014.

Vanney originally joined Toronto FC on December 11, 2013 as the club's assistant general manager and academy director. Vanney holds a USSF 'A' Coaching Licence and has been involved with the U.S. Soccer Development Academy.

Vanney previously held titles of director of soccer operations and director of Real Salt Lake-Arizona Youth Academy at Grande Sports World. It was there that he oversaw program and business development at the Grande Sports World facility. Vanney, Grande Sports World, and Real Salt Lake were responsible for creation of the first MLS Residential Academy in the United States, which began play in the Fall of 2010. Vanney also held a dual role at Chivas USA from 2011-2012 as assistant coach under Robin Fraser and technical director of the youth academy.

Vanney played professionally for 13 years, starting with the LA Galaxy in 1996. During his time with the Galaxy, Vanney helped lead the club to three MLS Cup championship finals, one Supporter's Shield, a US Open Cup Championship and a CONCACAF Champions Cup title. He was named to the MLS Best XI in 2000 and 2001. Following the 2001 season, Vanney transferred to SC Bastia, of France's Ligue 1, where he remained until 2005 helping the club reach the Coup de France Final in 2002. He rejoined MLS, signing with FC Dallas and spent two seasons with the Hoops; where he earned two All-Star selections, captaining the 2005 team to a 4-0 victory over Fulham. Vanney was traded to the Colorado Rapids in January 2007, and then to D.C. United later that same season. Vanney rejoined the LA Galaxy in February 2008 and retired at the conclusion of the season. During his playing career, Vanney earned 36 caps and scored one goal for the United States Men's National team. Vanney was added to the U.S. 2002 FIFA World Cup preliminary squad, but missed the tournament due to injury. He was also part of the U.S. side that won the 2005 CONCACAF Gold Cup.

Greg resigned at the end of the 2020 season after failing to progress past the first round of the playoffs for MLS Cup. This was probably the toughest season in TFC history as not only did the club (and all other clubs) need to battle the COVID19 pandemic, but when play resumed, they had to temporarily move 'home' to Rentschler Field in East Hartford, CT for the season due to the closure of the Canadian border and COVID restrictions that meant BMO Field could not be used for MLS play with US opposition. In spite of all this, TFC took second spot in the Supporters' Shield with the title only being decided on the last day of the season.

Greg leaves the club in far better shape than when he took over, amassing 3 MLS Cup Final appearances, 1 MLS Cup win, 1 Supporters Shield, 1 CONCACAF Champions League Final appearance, and 3 Canadian Championships (not including this year's final to be played in 2021). He also led TFC to a domestic treble in 2017 when TFC won MLS Cup, Supporters Shield and Canadian Championship, the first time in MLS history a team managed this.

It goes without saying that he will be a hard act to follow and leaves a remarkably successful legacy behind, having transformed TFC from what Danny Koevermans called "the worst club in the world" in 2012 to an MLS powerhouse by 2017 and with a great foundation to stay that way into the future.
