Founded in 1963 when remaining members of the Brooklin Stevenson Motors softball team blended with players from a team in Mount Zion, the Brooklin Concretes joined the Oshawa City and District Softball League and quickly established a reputation for on-field excellence. In just their second season, the Concretes advanced to the league semi-finals, a significant result in its own right for a team from a small community that was competing against some of the most elite players and teams of that era.
But it was at the regional and provincial levels where the Brooklin Concretes players realized their most significant achievements. Competing in the Ontario Amateur Softball Association (OASA) Intermediate C division playoffs, the Concretes captured Southern Ontario titles in 1964 and 1966, thereby earning the right to play for the All-Ontario championship in those two seasons; coincidentally, they were opposed by a team from Capreol on both occasions.
The 1964 team, led by Coach Dib Little, had to advance through four rounds of playoffs to capture their Southern Ontario championship. All rounds were best-of-three series, and the Concretes prevailed with an overall record of eight wins versus two losses. The All-Ontario championship was also a best-of-three series with all games to be played in Brooklin. After a narrow 2-1 loss in the opening game, the Concretes rebounded to secure their first provincial title by winning the next two games by scores of 3-1 and 4-2.
Now under the leadership of Coach Bill Harper, the 1966 Concretes faced an even tougher road to the OASA Intermediate C finals; this time, the team had to win six best-of-three playoff rounds to become Southern Ontario champions. Their successful run saw the team win 12 of 15 games, scoring a total of 127 runs to just 28 combined by all their opponents. Facing Capreol once more in the provincial final, the Brooklin team triumphed in short order, winning 2-1 and 5-1 to capture their second All-Ontario title in the minimum of two games.
