Leo Cahill lived in Etobicoke for 18 years. In that comparatively short time he made his presence known in much the same way as he made himself known in professional football circles.

It began in the early 1960s in Montreal, where Cahill was an assistant coach with the Montreal Alouettes football team. His move to Toronto shortly thereafter, which coincided with the start of nearly two decades of residency in Etobicoke, saw him take over direction of the Toronto Rifles of the Continental Football League. He made the move to the Argonauts as Canada celebrated its Centennial.

In his eight years as Argonaut coach, spread over twelve seasons, Cahill brought football to the forefront in Metro. Suddenly, the Argos were popular again and playing no small role in that popularity was Leo Cahill himself.

Among his coups as coach, and later as general manager, none was as notable as outbidding the NFL for the services of quarterback Joe Theismann.

Away from his professional life Cahill always found time for the City of Etobicoke, either running clinics for the area’s up and coming stars or doing a variety of charity work.
