Treliving was hired as Toronto’s general manager Wednesday, less than two weeks after firing Kyle Dubas
The 53-year-old Treliving left the Calgary Flames in April following nine seasons that included five playoff appearances and two 100-point seasons.
“Brad brings a wealth of knowledge from his years of experience as a general manager and hockey executive in Calgary, Arizona and beyond,” Leafs president Brendan Shanahan said in a statement. “He has earned tremendous respect amongst his peers throughout his years in the NHL and has built excellent relationships at all levels within the game.”
Treliving joins the Leafs at a crucial juncture in the wake of Shanahan’s stunning dismissal of Dubas on May 19.
The Original Six franchise, whose Stanley Cup drought stands at 56 years, won a playoff series for the first time in nearly two decades with a victory over the Tampa Bay Lightning this spring, but then lost to the Eastern Conference champion Florida Panthers in five games. 
Dubas, who had been Toronto’s GM since 2018 and didn’t have a contract beyond June 30, suggested at an end of season news conference May 15 he wasn’t sure he wanted to remain in the role — at least in part because of the stress on his young family.
A roller coaster five days followed, with Shanahan ultimately firing the 37-year-old Dubas despite previously wanting to keep his GM, and the now-unemployed executive eventually indicating to his boss he wished to stay.
Treliving is the third GM — joining Dubas and Hall of Famer Lou Lamoriello — hired in Toronto by Shanahan, whose so-called “Shanaplan” aimed at getting the storied franchise back on its feet when he came on board in 2014 has seen unparalleled regular-season success, but just that one series victory in eight attempts.
“I’m thrilled to join an Original Six team and recognize how much the Maple Leafs mean to this community,” Treliving said. “This is a very exciting day for my family and I.”
Treliving has a lot to deal with as he settles into his new office at Scotiabank Arena.
Treliving, who served in the Phoenix Coyotes’ front office for seven seasons before arriving in Calgary, will have to decide the future of head coach Sheldon Keefe, while stars Auston Matthews and William Nylander can sign contract extensions as of July 1.
Matthews and Mitch Marner have full no-movement clauses ready to kick in the same day. Nylander will have a 10-team list.
The NHL draft is also set for the end of June in Nashville, Tennessee, while the Leafs have 12 roster players primed to hit free agency at noon EDT on July 1.
The Flames, who missed the playoffs this season, won the Pacific Division in 2021-22 under Treliving before falling to the Edmonton Oilers in the second round.
Johnny Gaudreau then stunned the organization by leaving Calgary for the Columbus Blue Jackets in free agency last summer. Fellow star forward Matthew Tkachuk added another wrinkle by informing the team he didn’t plan to re-sign.
Treliving subsequently dealt the winger to Florida as part of a package that included forward Jonathan Huberdeau and defenseman MacKenzie Weegar heading to southern Alberta.
Huberdeau then signed an eight-year, $84 million contract extension with the Flames that kicks in next season.
Tkachuk, a Conn Smythe Trophy candidate as playoff MVP, and the Panthers open the Cup Final against the Vegas Golden Knights on Saturday night.
Despite the departures of Gaudreau and Tkachuk, the Flames looked like contenders ahead of the 2022-23 season.
The acquisition of Huberdeau and the signing of center Nazem Kadri was expected to fill the void left by Gaudreau and Tkachuk, but the mix wasn’t right for a group led by hard-nosed coach Darryl Sutter.
Huberdeau and Kadri finished well off their career-high points totals of the previous season — the former went from 115 with Florida to 55 in Calgary — while subpar goaltending was an issue much of the season
