Holzer has two assists and 10 penalty minutes in nine regular-season games with the Toronto Marlies this season. The 26-year-old Munich native was recalled by the Leafs earlier this season but has yet to play in a game.
Booth, a 30-year-old Detroit native, hasn't played for the Leafs since breaking his foot after blocking a shot in a pre-season game. He rejoins the NHL club after a two-game conditioning stint with the Marlies.
Toronto's next game is at Pittsburgh on Wednesday night.
