The mergers between all of these leagues continued in 1993 with the collapse of the Canadian Soccer League. This led to three Canadian teams, the Vancouver 86ers, Toronto Blizzard and Montreal Impact joining the American Professional Soccer League for the 1993 season. So by the summer of 1993, only two outdoor leagues competed for national attention in North America, the United States Interregional Soccer League and the American Professional Soccer League. However, by this time, the USISL was growing and the APSL was shrinking.
