Toronto Maple Leafs' potential general manager candidates

The search to replace fired Toronto Maple Leafs general manager Dave Nonis began immediately following, if not before, Sunday's announcement of his dismissal.

How deep club president Brendan Shanahan and his management team want to reach in the interview process will depend on whether they wait to see if more candidates become available during, or at the conclusion of, the Stanley Cup playoffs.

Ideally, teams prefer to have a new GM in place for the NHL draft, with this year's event set for June 26-27 in Sunrise, Fla. However, Maple Leafs assistant GM Kyle Dubas and director of player personnel Mark Hunter have been with the team for most, if not all, of the season and are well into their draft preparation, so it's not a must.

Peter Chiarelli and Doug Wilson have been rumoured for weeks to be on their wait out of Boston and San Jose, respectively, but it's not clear if Toronto would prefer to hire an experienced NHL GM or promote someone currently working as an assistant GM in the league.
