If 55,000 fans in Toronto, Ontario wasn't enough at UFC 129 in April, Canadian fight fans are getting a double dip in the year 2011.

That's because the promotion will return to "Queen City" for its upcoming UFC 140 event, which is scheduled for Dec. 10 at the Air Canada Centre, according to ESPN.com.

How's it feel to be spoiled, eh?

Of course, the Air Canada Centre doesn't seat anywhere near as many fans as the Rogers Centre. At its current configuration, the arena seats somewhere around 20,000, still a considerable number.

Based on the organizations track record, the UFC should have no problem filling it up.

UFC 129 featured Canadian superstar and Welterweight Champion Georges St. Pierre taking on Jake Shields on April 30. In addition, Jose Aldo vs. Mark Hominick and Randy Couture vs. Lyoto Machida filled the card with compelling match-ups.

That was enough to sell out the Rogers Centre with an astounding 55,724 frenzied fans, easily enough to shatter the record for both attendance and live gate.

That record was previously held by another show up in the Great White North, UFC 124, which was also headlined by St. Pierre in a grudge match against Josh Koscheck.

That fight took place in Montreal but the point stands -- Canada remains a hotbed for mixed martial arts and more specifically, the UFC.

However, this time around it's highly unlikely that "GSP" will be available to headline UFC 140, thanks to his scheduled title defense at UFC 137 on Oct. 29 against Nick Diaz.

One man who has already called for a spot on the card is Mark Hominick, who contested for the featherweight title in Toronto at UFC 129 in the co-main event.

Could he be making a return trip in his very next fight. Stay tuned.
