According to TSN.ca:
The mixed martial arts juggernaut enjoyed a record day at the box office Thursday, selling more than 42,000 tickets -- its entire original ticket block -- for UFC 129 on April 30 at the Rogers Centre.
"I LOVE CANADA!" UFC president Dana White told The Canadian Press in a text message.
The previous UFC attendance record was UFC 124 in Montreal, which drew 23,152 to the Bell Centre in December. White often refers to Canada as the mecca of mixed martial arts.
On Friday, another pre-sale is set for those who subscribe to the UFC newsletter. Tom Wright, the UFC's director of Canadian operations would not detail the possible total number of seats on sale but said 50,000 would be "pushing it."
