The Warriors began as Brampton Regents during the 1940s[citation needed] playing at the Junior B level.

As the Warriors folded for good at the end of the season, the Platers came within arm's reach of winning the National Title.

Three alumni of the Brampton 7Ups went on to play in the National Hockey League, all of them (Ken Broderick, Andy Brown, and Lyle Carter) were goaltenders playing a combined total of 106 NHL games.

Brown carries the distinction of being the last goaltender in the league to play without a protective mask, now a mandatory rule.

With the renaming and promotion for the Jr. A Warriors, a farm team was created at the Junior B level to feed them.
