"We're scheduled to do something in Canada later this year. We've got everything on hold right now to see if New York happens. So we'll see," White told a stop on the UFC 189 World Championship Tour on Friday.
The answer drew boos from the crowd at the Toronto Eaton Center.
"Yeah, I know, I know. Bad answer," said White.
The UFC has been trying for years to get New York state to sanction mixed martial arts so it can stage a show in New York City.
A September 2014 show in Toronto, featuring a rematch between light-heavyweight Jon (Bones) Jones and Sweden's Alexander (The Mauler) Gustafsson, was shifted to Las Vegas.
UFC 186 is scheduled for April 25 in Montreal. A televised Fight Night show is also planned for Canada this year, possibly in Saskatchewan.
