Seguin was moved from wing to center after being acquired by the Dallas Stars from the Boston Bruins in a trade on July 4, 2013. All he did was score at least 33 goals in each of his first three season with the Stars, establishing himself as one of the NHL's elite scorers.

Seguin was simply fulfilling the promise the Bruins projected when they selected Seguin with the No. 2 pick in the 2010 NHL Draft.

He jumped straight to the NHL and had had 22 points (11 goals, 11 assists) in 2010-11 despite averaging 12:13 of ice time during his rookie season. Seguin also contributed seven points (three goals, four assists) in 13 Stanley Cup Playoff games to help the Bruins win their first championship since 1972.

Seguin began to break out the next season, finishing with 67 points (29 goals, 38 assists) and a plus-34 rating that was second in the NHL. He followed that up by scoring 16 goals and finishing with 32 points during the lockout-shortened 2012-13 season. But after Seguin scored one goal on 70 shots during Boston's run to the 2013 Stanley Cup Final, the Bruins traded him to the Stars.

Seguin tied Joe Pavelski and Max Pacioretty for the NHL lead with three hat tricks in 2013-14, his first season with Dallas, and has continued to pile up the goals and points, scoring 40 goals in a season for the first time in 2017-18.

He led the Stars in scoring again in 2018-19 (80 points; 33 goals, 47 assists) and 2019-20 (50 points; 17 goals, 33 assists). Seguin contributed 13 points (two goals, 11 assists) during Dallas' run to the 2020 Stanley Cup Final.

Seguin started the 2023 Stanley Cup Playoffs with four power-play goals in the Western Conference First Round, a Dallas/Minnesota North Stars record and 20 years since any player scored more on the power play in a single round (Doug Weight scored five for the St. Louis Blues in the 2003 conference quarterfinals).

A native of Brampton, Ontario, Seguin played his junior hockey with Plymouth in the Ontario Hockey League, where he scored 69 goals and had 173 points in 124 games.

Seguin also helped Canada finish first at the 2015 IIHF World Championship, where he led all scorers with nine goals.
