"Most of the tickets for UFC 83 were sold in the first 24 hours of our UFC Fight Club (Premium fan organization owned and controlled by UFC)  pre-sale, and the rest were gone within one minute of the public on-sale today,"  stated UFC President Dana White, "I'm excited to say that this event is a sellout, and the fastest one in UFC history, so it's safe to say we definitely will be back in Canada after this inaugural event."

The main event of the evening will be Matt Serra defending the UFC Welterweight Championship against Montreal's own Georges St. Pierre, with whom Serra has split two matches. With over 21,000 fans live in attendance, the crowd will break UFC's record  of 19,049, set at UFC 68 on March 3, 2007, at the Nationwide Arena in Columbus, Ohio, which was headlined by Randy Couture's return to the Octagon to win the Heavyweight Title from Tim Sylvia.
