What Canadian basketball star co-owned Vancouver Whitecaps FC in 2015?

The Canadian basketball star who co-owned Vancouver Whitecaps FC in 2015 was Steve Nash.

Born in Johannesburg and raised primarily in British Columbia, Nash became one of Canada’s most celebrated basketball players. He played point guard in the NBA, won the league’s Most Valuable Player award twice, and was known for his precision passing, outside shooting, and fast-paced style. He also represented Canada internationally and later served as general manager of the Canadian men’s national basketball team.

Nash joined the Vancouver Whitecaps ownership group in 2008, before the club entered Major League Soccer. Vancouver began MLS play in 2011, making the Whitecaps one of Canada’s three MLS clubs alongside Toronto FC and Montreal Impact, now CF Montréal. Nash’s involvement connected one of Canada’s best-known basketball figures with professional soccer in his home region.

The question refers to ownership, not playing. Nash never played for the Whitecaps; he was an investor and co-owner. He was also involved in other sports investments, including a later stake in Spanish football club Mallorca.
