All it takes is a sold-out a baseball stadium to convince the UFC to come back to your city in short order. is reporting that the UFC will return to Toronto on Dec. 10 for UFC 140.

The UFC is headed back to the city of Toronto for a second time in 2011, where it hosted the most successful show in company history, co-owner Lorenzo Fertitta told on Tuesday.

UFC 140 will take place at the Air Canada Centre on Dec. 10.

It’s important to note that the Air Canada Centre seats up to 20,000, not 55,000 like the Rogers Centre, so this won’t be as big of a show as UFC 129 was. As MMA-crazed as Toronto is though, it will surely be a success.

The question is: Who will headline?
