Born and raised in Örnsköldsvik, Sweden, Sedin and his identical twin brother Henrik played together throughout their careers; the pair were renowned for their effectiveness as a tandem.

[2] Sedin tallied 393 goals and 648 assists in 1,306 games played in the NHL, ranking him as the Canucks' second-highest points scorer all time, behind only his brother Henrik.

He played four seasons with Modo (including a return in 2004–05 due to the NHL lockout), helping the club to two consecutive appearances in the Le Mat Trophy Finals, in 1999 and 2000, where they lost both times.

[4] As they were unlikely to be picked by the same team, their agent, Mike Barnett, president of international talent agency IMG, presented them with two options to circumvent the usual NHL draft process, allowing them to play together.

[24] Finishing the campaign with that goal total, he tied for second among League rookies in scoring with Shane Willis of the Carolina Hurricanes, behind Brad Richards of the Tampa Bay Lightning.

[23] Daniel received one third-place vote from the Professional Hockey Writers' Association for the Calder Memorial Trophy as NHL rookie of the year, finishing eighth in award balloting overall.

[32] Facing the Presidents' Trophy-winning and eventual Stanley Cup champion Detroit Red Wings in the first round of the 2002 playoffs, they were eliminated in six games.

[3] The Canucks won the Northwest Division title in the regular season and were the third seed in the West Overall ,[38] before losing to the sixth-seeded Calgary Flames in the first round of the playoffs.

[43] His scoring success that season was influenced, in part, by the signing of winger Anson Carter, who played on the Sedins' line and led the team in goal-scoring.

[43] Vancouver's head coach at the time, Marc Crawford, recalled that season as marking the Sedins' ascent to leaders on the team, stating that "by the end of that year, they definitely were our top guys.

Daniel notched his second career NHL hat-trick on 6 February, scoring two goals against Edmonton Oilers goaltender Dwayne Roloson and one into an empty net.

[36] Winger Taylor Pyatt, acquired in a trade from the Buffalo Sabres during the 2006 off-season, replaced Carter as the Sedins' linemate[49] and went on to score a career-high 23 goals.

[57] Bernier was later removed;[58] and on 12 February 2009, Canucks head coach Alain Vigneault moved Alexandre Burrows up from the third line during a game against the Phoenix Coyotes.

[61] Set to become unrestricted free agents on 1 July 2009, Daniel and Henrik began negotiating with the Canucks in the 2009 off-season and were reported to have asked for 12-year, $63 million contracts in mid-June.

[62] With free agency looming, Canucks general manager Mike Gillis visited the Sedins in Sweden, where they agreed on identical five-year, $30.5 million contracts on 1 July.

Although Daniel finished the game and recorded three assists on goals by Henrik, Alexandre Burrows and Steve Bernier, x-rays a few days later on 11 October revealed the fracture.

It marked the first time in NHL history that brothers led the League in scoring in back-to-back seasons, as Henrik had won the previous year.

Chicago Blackhawks forwards Doug and Max Bentley also won separate scoring titles, but had achieved the feat three years apart in 1943 and 1946, respectively.

Daniel won the Lindsay Award over forwards Steven Stamkos of the Tampa Bay Lightning and Corey Perry of the Anaheim Ducks, respectively.

[98] He remained out of the lineup for the first three games of the 2012 playoffs, all of which the Canucks lost against the eighth-seeded and eventual Stanley Cup champion Los Angeles Kings.

The call would later be the subject of controversy as it was believed by many in the media, such as National Post journalist Cam Cole, as well as teammates, such as Henrik, that Daniel had made contact with Wingels shoulder-to-shoulder, which according to NHL rules, should not result in a boarding penalty.

[9] The Canucks did not qualify for the playoffs for the first time since 2008,[110] as Daniel had a 23-game goal-scoring drought and injured his hamstring during the Heritage Classic against the Ottawa Senators, on 2 March 2014 which forced him to miss nine games.

During the second period of that game, a hit by the Calgary Flames' forward Paul Byron sent Daniel's head into the boards and ended his season.

[112] On 23 November 2014, Daniel played his 1,000th NHL game against the Chicago Blackhawks, joining Henrik and Trevor Linden as the only players in franchise history to reach that milestone.

[9] Despite his continued individual productivity, the Canucks as a team finished 28th in the NHL in points and third-to-last place in the league overall, failing to reach the postseason for the second time in three years as a result.

[130] On 30 November 2017, Daniel reached the 1,000-point milestone by scoring a power play goal in a 5–3 win against the Nashville Predators against goaltender Pekka Rinne, joining Henrik as the only players to gain 1,000 points in the Canucks organization.

[135][136] Despite their retirement, the Sedin brothers were named finalists for the King Clancy Trophy, awarded to the player who best exemplifies leadership qualities on and off the ice and gives back to his community,[137] which they won on 20 June.

[140] On 22 June 2021, it was announced that Henrik and Daniel would join the Canucks Hockey Operations department and were named Special Advisors to the General Manager.

This once led Canucks general manager Brian Burke to publicly complain, commenting during a 2002 playoff series against the Detroit Red Wings, "'Sedin' is not Swedish for 'punch me or headlock me in a scrum.

[170] After earning a bachelor's degree in psychology at the University of British Columbia[171] Marinette became involved with the Canucks Family Education Centre, helping female immigrants transition to the English language.
