This is the first major adjustment for Treliving since he joined Toronto’s staff last May. Shanahan had parted ways with former GM Kyle Dubas — who originally hired Keefe to replace Babcock after also bringing Keefe to the organization when he was GM of the Marlies’ prior to that — and introduced Treliving in the role shortly after. Treliving opted to extend Keefe before last season began, touting Keefe’s “clear vision and direction for where the team needs to go.”

Now the hunt for Keefe’s successor will get underway in what could be a busy offseason for the Leafs. Toronto has key skaters including Auston Matthews and William Nylander signed to long-term contracts. They want to capitalize on that core with success right now, particularly in the playoffs. The other pieces of the Leafs’ designated Core Four — Mitch Marner and John Tavares — will be entering the final year of their current deals this season. Both would be eligible to sign extensions in Toronto on July 1.
