"Well, that's (Leafs President Brendan Shanahan's) decision," Leiweke said, as quoted by the Toronto Sun. "And that's (Leafs GM) Dave Nonis' decision and the two of them are spending a lot of time together.
"There are decisions coming soon. I know where these guys are at on their decision-making, we're not there yet, but they are getting there. We will not lack in our ability to make tough decisions around here. I promise you."
It has been widely speculated that the Leafs would fire Carlyle and the team's coaching staff, though the Sun suggests other moves, including ones within the team's front office, could be made, as well.
Roster moves are also being discussed, as several players may not return to the Leafs' lineup next season.
Pending unrestricted free agents Nikolai Kulemin, Paul Ranger, Troy Bodie, Mason Raymond, Jay McClement and Dave Bolland are all up for new deals, and it's believed on a select few may be brought back.
"No one is untradeable," Leiweke said. "Now, that does not mean a damn thing. What I know is this. Brendan is meeting with each guy one on one. Brendan and Dave are spending a long time talking about how do we get better."
The Leafs aren't expected to re-sign Kulemin, while Bolland's demands may be too high for Toronto's liking.
