NIAGARA FALLS, Ont. - Daredevil Nik Wallenda will likely find out this week if he will be allowed to walk a tightrope over Niagara Falls.

The Niagara Parks Commission plans to deliver its decision to the performer by Wednesday. Wallenda made his formal pitch for the high wire act to the board last month.

The stunt has the approval of U.S. lawmakers but it has been a tough sell on this side of the border, where the commission has a rule against such stunts.

Wallenda maintains 500 million people around the globe would watch him inch across the Horseshoe Falls, and predicts an economic payoff for Niagara of $120 million.

Commission chairwoman Janice Thomson says tourists expect to see the natural splendour of the falls, and she doesn't want them to experience something "opposite to what they were expecting."

Thomson also worries about the safety of the spectators and first responders. Wallenda has tried to calm those fears by talking up the expertise of his own rescue team.
