Bob is correct. The promoters called Jim Manion and said that they will not have the funds to sustain the pro show this year because of the lack of sponsorships, and a bunch of other situations, including the hotel wanting some money up front, from rooms, venue, etc, plus others.
This was not the IFBB's fault, nor any of the athletes. The promoter, Winston, loves bodybuilding, has been his life for 30 years, and is truly one of the most influential figures in the history of bodybuilding, as many will tell you, he has unfluenced it quite a lot 20-30 years ago.
Isaac and I had dinner with Winston and others at the Olympia, and he is a cool guy with lots of great stories. This was not an easy decision for him and his family, but losing a lot of money is something that they didn't want to continue at the moment. They took a major loss in the last few years, but it would of been greater this year.
Toronto / Niagara Falls is a tough place to have a show, due to lack of audience and sponsorships. Still, as anyone will tell you, it was a great scenic venue and one of the coolest place to have a show.
Really sorry to hear that.
