UFC 129: St-Pierre vs. Shields was an epic mixed martial arts event held by the Ultimate Fighting Championship on Sunday May 1st 2011 (aus time) at Rogers Centre in Toronto, Ontario.
The event was the sixth that the UFC has hosted in Canada and the first in Ontario since mixed martial arts was legalized in the province in August 2010.
The event was the largest UFC event in North American history and coincided with a two-day UFC Fan Expo at the Direct Energy Centre.
UFC officials had originally planned for the Rogers Centre to be configured to hold 42,000 fans for UFC 129. The UFC put those tickets on sale to UFC Fight Club members in a special pre-sale on February 10, 2011, selling nearly all of them. They released and sold more tickets the following day to UFC newsletter subscribers in a second special pre-sale. UFC 129 then sold out when tickets went on sale to the general public on February 12, with officials scrambling to up the number of seats to 55,000.
