Toronto Raptors [SEP] Introduction
The Toronto Raptors are a Canadian professional basketball team based in Toronto. The Raptors compete in the National Basketball Association (NBA) as a member of the league's Eastern Conference Atlantic Division. They play their home games at the Scotiabank Arena, which they share with the Toronto Maple Leafs of the National Hockey League (NHL). The team was founded in 1995 as part of the NBA's expansion into Canada, along with the Vancouver Grizzlies. Since the 2001–02 season, the Raptors have been the only Canadian-based team in the league, as the Grizzlies relocated from Vancouver to Memphis, Tennessee. As with 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 franchise set league-attendance records and made the NBA playoffs in 2000, 2001, and 2002.
