Gill joined Merrimack College in October, and in 10 NCAA games during the 2025-26 season, he has 10 points (four goals, six assists) and 24 PIM. A free agent in the NHL, Gill will look to impress during his time in the NCAA and attempt to earn a look from an NHL team in the future.

The New York Islanders did not sign Gill to an entry-level contract as of June 1, 2025. He is an unrestricted free agent.

2023, fifth-round pick, 145th overall, Justin Gill recently signed an AHL contract with the Bridgeport Islanders but will play this season in the ECHL. Last season, Gill finished with 40 goals, 58 assists, and 98 points for Baie-Comeau Drakkar, finishing two consecutive seasons with more than 90 points in the QMJHL. This year, look for Gill to carve out a role on the ECHL roster with potential for the occasional call-up to Bridgeport. However, already 21 years old, he has an uphill battle to prove himself to the management and is likely to be a bottom-six forward in the big leagues.
