The UFC confirmed the event and date via Twitter Wednesday after UFC co-owner Lorenzo Fertitta revealed the details Tuesday to ESPN.com.
The first Toronto show this past April was a huge financial success for the promotion. Headlined by Georges St-Pierre defending his title against Jake Shields, UFC 129 became the largest UFC event in North American history with an official attendance of 55,724 and gate of $12.1 million.
With UFC 140 taking place at the Air Canada Centre instead of the Rogers Centre, the UFC will go back to running average-sized shows to stay true to the UFC experience. The Air Canada Centre, home of the NHL's Toronto Maple Leafs, seats at a max of just under 20,000.
No fights have been announced yet for UFC 140, which will take place a week after The Ultimate Fighter 14 Finale.
