Ottawa Fury FC

On June 20, 2011, the North American Soccer League announced that Ottawa had been awarded an expansion franchise. The team would join the league in 2014 once developments at Lansdowne Park were completed. In February 2013, the club ran a campaign to select a name and received over 4,000 submissions. Club president John Pugh announced that Ottawa Fury FC was chosen as the name.

On May 23, 2013, the club named Marc Dos Santos as the first head coach. Two days later, the official crest was revealed at an event open to season ticket holders and supporters groups. In the final months leading up to the 2014 season, the club also named Martin Nash as assistant coach, David Bellemare as goalkeeping coach and Philip Dos Santos as technical director.

With Lansdowne Park not ready for the 2014 spring season, the club agreed a short-term deal to play at Keith Harris Stadium. After going unbeaten in five pre-season friendlies, Ottawa Fury lost 2–0 at the Fort Lauderdale Strikers in their first competitive match on April 12, 2014. The club finished the spring season in sixth with three wins from nine games. Ottawa Fury moved into Lansdowne Park ahead of the fall season, and lost 1–0 to the New York Cosmos in their first match at the new stadium on July 20. After failing to record a win in their first six matches of the 2014 fall season, the club finished in eighth place.

Ottawa Fury added Chelsea academy coach Darko Buser to the club's management team for the 2015 season, and after another unbeaten pre-season in 2015, ended the 2015 spring season in ninth place. The club saw great improvement for the 2015 fall season, and were crowned champions with 45 points from 20 games and sitting six points clear of Minnesota United. Ottawa beat Minnesota in extra time with a 2–1 victory in the Soccer Bowl semi-final, but lost 3–2 to the New York Cosmos in the final a week later.

In November 2015, Marc Dos Santos stepped down as head coach to join Sporting Kansas City as assistant coach having announced his intentions to the club two months earlier. On November 20, the club named Paul Dalglish as his replacement. The following month, Philip Dos Santos left his position as technical director and was replaced by Buser. A third consecutive unbeaten pre-season campaign followed, but the club could only manage a ninth-place finish in the 2016 spring season with nine points from a possible 30. Ottawa Fury finished the 2016 fall season bottom of the table amidst rumours the club would leave the North American Soccer League.

On October 25, 2016, the club announced that they would join the United Soccer League for the 2017 season. At the time of the announcement, it had been reported that the Fury were losing up to $2 million per year while operating in the North American Soccer League.

In December 2016, the Montreal Impact announced an affiliation agreement with Ottawa Fury after disbanding their reserve side FC Montreal. The club remained eligible for the Canadian Championship.

On August 14, 2017, Dalglish left his role at Ottawa Fury. Club president John Pugh announced that Dalglish had informed him of his intention to leave the club for personal reasons, and two days later the club and Dalglish decided to mutually part ways. Former player and current assistant coach Julian de Guzman took over as interim head coach for the remainder of the season. The Fury ended their first United Soccer League campaign in 10th place, missing out on the Conference Playoffs by six points.

On December 21, 2017, the club announced that Nikola Popović would take over as their new head coach. De Guzman remained with the club as general manager.

On September 5, 2018, Mark Goudie, president and CEO of Ottawa Sports and Entertainment Group, officially dispelled rumours about the club joining the Canadian Premier League (CPL) for the league's first season in 2019, citing the stability of the USL as their reason to remain there. Goudie, however, stated that the club supports the CPL's mission of expanding soccer in Canada, and did not rule out joining it in the future. On December 12, 2018, the Canadian Soccer Association (CSA) received a letter from CONCACAF, stating that the Ottawa Fury's sanctioning to play in the 2019 USL Championship season would be revoked, despite the club receiving approval from both the CSA and the United States Soccer Federation (USSF). On December 13, 2018, CONCACAF released a statement saying that they "never received a formal request from any party to consider sanctioning the participation of the Ottawa Fury in the 2019 season of the USL, despite public announcements by Ottawa Fury that it would be doing so". CONCACAF additionally stated that the launch of the CPL precludes the "exceptional circumstances" provision which allowed Canadian clubs to participate in USSF-sanctioned leagues. On December 19, 2018, OSEG filed for arbitration with the Court of Arbitration for Sport in an attempt to reinstate the Fury's sanctioning in the USL. Two days later, the club revealed that it would be allowed to continue to play in the USL for the 2019 season.

In the 2019 season, the Fury reached the play-offs for the first time since joining the USL. Their play-off run, however, only lasted one game as they were knocked out in the play-in round by the Charleston Battery, who advanced on penalties. One week later, on October 30, the Fury announced they would not be renewing the contract of head coach Nikola Popović.

On November 8, 2019 the Fury announced that they had not been sanctioned to play in the USL Championship for the 2020 season and would be suspending operations. The team had received sanctioning from Canada Soccer, but not from the USSF and CONCACAF. On December 11, the Fury announced the sale of its franchise rights to the ownership group of Miami FC, with Miami set to participate in the 2020 USL Championship season.
