Lettieri was waived by Toronto on Thursday, according to James Mirtle of The Athletic.
Lettieri came up big for AHL Toronto during its 2026 Calder Trophy-winning run, supplying 11 goals and 26 points in 25 playoff outings. He also had 14 goals and 42 points in 55 regular-season appearances with AHL Toronto in 2025-26. Although the 31-year-old is great in the minors, he's unlikely to spend much time, if any, in the NHL this season.
