The Toronto Raptors are a Canadian professional basketball team based in Toronto, Ontario. The Raptors compete in the National Basketball Association (NBA), as a member club of the league's Eastern Conference Atlantic Division. The team was established in 1995, along with the Vancouver Grizzlies, as part of the NBA's expansion into Canada. After the Grizzlies relocated to Memphis to become the Memphis Grizzlies in 2001, the Raptors became the only Canadian-based team in the NBA. They originally played their home games at SkyDome (later renamed Rogers Centre in 2005), before moving to the Scotiabank Arena (originally named the Air Canada Centre) in 1999.
Like most expansion teams, the Raptors struggled in their early years, but after the acquisition of Vince Carter through a draft day trade in 1998, the team set league-attendance records and made the NBA playoffs in 2000, 2001, and 2002. Carter was instrumental in leading the team to their first playoff series win in 2001, where they advanced to the Eastern Conference semifinals. During the 2002–03 and 2003–04 seasons, they failed to make significant progress, and Carter was traded in 2004 to the New Jersey Nets.
After Carter left, Chris Bosh emerged as the team leader. In the 2006–07 season, Bryan Colangelo was appointed as General Manager, and through a combination of Bosh, 2006 first overall draft pick Andrea Bargnani, and a revamp of the roster, the Raptors qualified for their first playoff berth in five years, capturing the Atlantic Division title. In the 2007–08 season, they also advanced to the playoffs, but failed to reach the post-season in each of the next five seasons. Colangelo would overhaul the team's roster for the 2009–10 season in a bid to persuade pending free agent Bosh to stay, but Bosh would depart to sign with the Miami Heat in July 2010, ushering in yet another era of rebuilding for the Raptors.
Masai Ujiri replaced Colangelo in 2013, and helped usher in a new era of success, led by backcourt duo Kyle Lowry and DeMar DeRozan. The Raptors returned to the playoffs the following year, and became a consistent playoff team in every year of Ujiri's tenure. The team also won four Division titles, and registered their most successful regular season in 2018. However, the team's failure to reach beyond the second round of the playoffs prompted the Raptors to fire head coach Dwane Casey and trade DeRozan for Kawhi Leonard that summer.
