Toronto has had teams in a number of first division soccer leagues of the United States. The Toronto Greenbacks were members of the North American Soccer Football League for its two years of existence in 1946–47. In 1967, two rival leagues began play: the United Soccer Association (USA) and National Professional Soccer League (NPSL). Both leagues had Toronto-based clubs with Toronto City (owned by future owner of Maple Leaf Sports & Entertainment Steve Stavro) joining the US and the Toronto Falcons in the NPSL and both playing their games at Varsity Stadium. Following the merger of the two leagues for the 1968 season only the Falcons survived, with Stavro selling his team back to the league for $160,000. However, the Falcons only played a single year in the newly founded North American Soccer League (NASL) with losses reported to be up to $500,000 before folding. The following year, Toronto City was invited to join the NASL. Subsequently, the Toronto Metros joined the NASL in 1971, and though they were renamed the Toronto Metros-Croatia in 1975 following the purchase of 50% of the club for $250,000 by the Toronto Croatia of the National Soccer League, and again in 1979 to the Toronto Blizzard following the acquisition of 85% of the team by Global Television Network for $2.6 million, the team played until the NASL folded in 1984.
