The Toronto Maple Leafs were a high-level minor league baseball club located in Toronto, Ontario, Canada, that played from 1896 to 1967. While the Maple Leafs had working agreements with numerous Major League Baseball clubs after the introduction of farm systems in the 1930s, they achieved great success as an unaffiliated club during the 1950s, when they were the strongest team on the field and in attendance in the Triple-A International League.
