Matthew Highmore (4th liner who was Adam Gaudette's return when he was traded to CHI from VAN) signed with STL.
Johan Larsson signed with PIT (not fully confirmed yet). Would have been a decent bottom 6 option.
Benning and Nutivaara to SJS. Benning got 4 years at just over one mill (really weird deal but fair enough) and Nutivaara is TBD.
There have been a few other smaller deals but that is about it for ones that have not been reported yet.
Leafs need RD depth and Michael Stone is really the only good RH guy left (who is not a full time guy like Subban, Klingberg, or Stralman). Otherwise, we'd need to turn to guys like Niku, Mete, Beaulieu, Dronov, or de Haan who have been listed as switch guys, or guys like Duszak who were good AHLers but have no NHL experience.
