"On behalf of the MLSE Board of Directors, and certainly our company and fans as well, we are very pleased to see Brendan continue in his role as president of the Toronto Maple Leafs," said Larry Tanenbaum, chairman of Leafs ownership group MLSE. "Brendan's positive impact on this team has not only been felt on the ice, where the team is on an impressive path, but throughout the league, with the Leafs' alumni, and in the community.
"We look forward to continued success for the Maple Leafs under Brendan's leadership over the next six years."
The former head of the NHL's Department of Player Safety, Shanahan joined the Maple Leafs in April 2014 and has overseen massive organizational changes since taking over.
Under Shanahan, the Leafs brought in Mike Babcock as head coach and Lou Lamoriello - since replaced by Kyle Dubas - as general manager. With Shanahan at the helm, the team also drafted several members of its young core including Auston Matthews, Mitch Marner, and William Nylander, and made a franchise-altering free-agent splash with the signing of John Tavares last July.
Shanahan's arrival has paid major dividends for Toronto, as the team has transformed from a perennial cellar dweller into a legitimate Stanley Cup threat. The Leafs have qualified for the playoffs in each of the last three campaigns and have now recorded back-to-back 100-point regular seasons for the first time in franchise history.
