Maple Leaf Sports and Entertainment president and CEO Tim Leiweke announced Thursday that he will step down after just over a year on the job.
Leiweke will continue in his role until June 30, 2015 or until a successor is appointed.
"Under Tim's leadership, MLSE has made a number of key moves to strengthen our organization on the path to championship success," MLSE chairman Larry Tanenbaum said in a statement. "We look forward to working closely with Tim to build on this foundation and further accelerate our momentum as we seek a new leader for MLSE."
Leiweke, who joined the company in April of 2013, said he plans to pursue his goal of owning and operating his own business following his departure from MLSE.
"It's an honor to lead MLSE, a world-class organization in a city and a country so passionate about sports. But with new opportunities on the horizon, it's time for me to begin the transition from sports and entertainment executive to entrepreneur," Leiweke said in a statement. "Right now, my total focus is here at MLSE and I look forward to working with the Board and MLSE team to continue strengthening our franchises while ensuring a smooth transition to a new leader."
Since his arrival at the Toronto Maple Leafs parent company, Leiweke has made proclamations about the direction of one of the NHL's most storied franchises.
Leiweke said early on he already had the Maple Leafs Stanley Cup parade route planned despite the fact that the team hadn't won the championship since 1967.
The Maple Leafs missed the playoffs last season after a late-season collapse.
Prior to joining MLSE, which also operates the NBA's Toronto Raptors, Toronto FC of MLS and the Toronto Marlies of the American Hockey League, Leiweke spent 17 years with sports entertainment power AEG.
