Tom Anselmi resigned as chief operating officer of Maple Leaf Sports and Entertainment Ltd., the company said Friday in a release. Anselmi joined MLSE in 1996 and was instrumental in the development of the Air Canada Centre, home to the company's Toronto Maple Leafs. In 2004 he was appointed chief operating officer and later named president of MLSE in September of 2012. "I am from this community, and I’m a huge fan of our teams, so being part of the growth of this organization into one that is admired in the industry has been a real privilege," Anselmi said in a statement. Tim Leiweke took over as president on June 30. "The entire organization, including our ownership group, is grateful to Tom for his many contributions to the success of Maple Leaf Sports & Entertainment over the years," Leiweke, now president and CEO of MLSE, said in a statement.
