Ethan Del Mastro Bio
Ethan Del Mastro (born January 15, 2003) is a Canadian professional ice hockey player who plays as a defenceman for the Chicago Blackhawks of the National Hockey League (NHL). Selected 105th overall by the Blackhawks in the 2021 NHL Entry Draft, he has progressed through the organization’s development system and made his NHL debut in April 2024. Standing 193 cm tall and weighing roughly 95 kg, he has the prototypical frame of a modern, two-way NHL defenceman.
Born and raised in Burlington, Ontario, Canada, Del Mastro came up through junior and minor-pro pathways before turning professional. His journey from a fourth-round selection to an NHL roster spot reflects steady development within the Blackhawks’ pipeline rather than an overnight rise.
Early Life and Background
Ethan Del Mastro was born on January 15, 2003, in Burlington, Ontario, a city on the western shore of Lake Ontario in the Greater Toronto and Hamilton Area. Burlington has long produced competitive amateur hockey talent, and Del Mastro grew up immersed in that environment. His Canadian roots and Ontario upbringing shaped his early introduction to the sport, where he developed the foundational skills that would later attract NHL scouts.
From a young age, Del Mastro showed the size and skating ability that have become trademarks of his game. He played his youth hockey in the Ontario minor-hockey system, progressing through age-group divisions while continuing to add height and strength. His steady growth trajectory positioned him as a legitimate prospect entering his draft year.
Path to Hockey
Del Mastro’s path to professional hockey included time in the Ontario Hockey League (OHL), one of the top developmental leagues in North America. As a left-shot defenceman with size and mobility, he drew attention from NHL scouts during his junior career and was rated as a prospect with both offensive upside and defensive reliability.
The Chicago Blackhawks selected him in the fourth round, 105th overall, in the 2021 NHL Entry Draft. He signed a three-year entry-level contract with the team on April 22, 2022, formally beginning his professional pathway. The contract signalled the organization’s belief in his long-term potential and set the stage for his transition to the American Hockey League (AHL).

He spent the bulk of the 2022–23 and 2023–24 seasons anchoring the IceHogs’ blueline, refining his defensive game and adjusting to the pace of professional hockey.
