Former US team manager Bob Bradley was hired to coach Toronto six days after leaving Los Angeles FC.
Bradley, 63, will lead his son Michael, captain of Toronto.
The team fired Chris Armas in July, after winning just one of 11 games. He had tied two and lost the remaining eight.
With Javier Pérez as interim manager, he finished 13th out of 14 teams in the Eastern Conference, with six wins, 18 setbacks and 10 draws.
The departure of Genreal manager Ali Curtis was announced on Monday.
Bradley spent five years (2006-2011) at the helm of the US team. In the MSL league it accumulates 182 games won, 86 draws and 127 defeats. He is the third most victorious coach, behind Bruce Arena and Sigi Schmid.
In his long career he directed the Chicago Fire, the MetroStars and Los Angeles FC in MLS, the United States, Egypt (2011-13), Stabaek of Norway (2014-16), the French Le Havre and (2015-16) Swansea of the English Premier League. AP
