Brisson was placed on waivers by the Maple Leafs on Thursday, James Mirtle of The Athletic reports.
Brisson agreed to a one-year, two-way contract with the Maple Leafs in early September after he wasn't tendered a qualifying offer from the Rangers during the offseason. He'll be left off the Maple Leafs' Opening Night roster and will head to AHL Toronto if he clears waivers.
