[8][9][10][11] By 1980, Harold Ballard, owner of the Leafs, had decided that they needed a developmental team of their own,[9] with a spokesperson citing the limited number of roster spots as the rationale for the move.

[2][3] MLGL launched the Cincinnati Tigers in the old Central Hockey League in 1981 to serve as their own affiliate, while retaining their share of the New Brunswick Hawks.

[4][12][13][15][16] That same summer, with Chicago having already pulled out of New Brunswick in favour of affiliating with the Springfield Indians on their own,[4][13][16][17] the Maple Leafs announced that they would not operate the team in Moncton the following year after they couldn't come to terms with the city on a new arena lease,[4][13][17] even though the team had the fifth highest attendance in the league.

[18] The Maple Leafs wanted to relocate the team closer to Toronto, with both St. Catharines and Niagara Falls in Ontario potential destinations for the franchise.

[13][20][21][22][23][24] However, following protests by fans in St. Catharines[25] and threats by Ballard to suspend the Moncton franchise to prevent another AHL team from playing in the city[13] and to sue the Sabres and NHL for $20 million,[22][23] the relocation was approved unanimously and the franchise became the St. Catharines Saints, serving as the Maple Leafs' primary affiliate.
