Known as an enforcer, he played for the Toronto Maple Leafs, New York Rangers, and Winnipeg Jets over a 16-year NHL career.

[1] Domi was born in Windsor, Ontario, to Albanian parents,[2][3] and grew up in nearby Belle River (now part of Lakeshore).

[4] In his first full season with the Petes in 1987–88, he recorded an OHL career-high 22 goals and 43 points over 60 games, to go along with 292 penalty minutes, earning a reputation as an enforcer.

[4] Domi turned professional in 1989–90 with Toronto's American Hockey League (AHL) affiliate, the Newmarket Saints, recording 14 goals and 25 points over 57 games, along with 285 penalty minutes.

[13] That year, he famously knocked New York Rangers defenceman Ulf Samuelsson unconscious with a sucker punch to the face.

"[18] Domi was fined $1000, the maximum allowable at the time by the NHLPA's collective bargaining agreement, but received no suspension.

[19] On May 3, 2001, in the closing seconds of Game 4 of the 2001 Eastern Conference Semi-finals, well away from the play, Domi threw an elbow at the head of New Jersey Devils defenceman Scott Niedermayer, knocking him unconscious.

[28] Domi stated publicly that he was not happy with being benched, a fact that was underlined by his staying in his hotel room, not arriving at the game until after the second period and was widely regarded as a contributing factor in the decision to buy out his contract.

Following his retirement, Domi accepted a position in broadcasting with The Sports Network (TSN),[33] a stint that lasted less than a month.

In October 2009, Domi began competing as a pairs figure skater on the Canadian Broadcasting Corporation reality show Battle of the Blades with Christine Hough.

[36] Domi has three children from his marriage to his ex-wife, Leanne: daughters Carlin and Avery Rose, and son Max, who is a current NHL player.
