The Thunder Bay North Stars loss is the London Knights gain.
Rookie forward Zach Grzelewski, a sixth-round pick in last summer’s Ontario Hockey League draft, has agreed to join the Knights and will make his major junior debut on New Year’s Eve in a game against the Trevor Letowski-coached Sarnia Sting.
The 16-year-old Thunder Bay native had 20 goals and 18 assists in just 28 games with the North Stars.
