The Blades started as a Junior C team, and made it to the Clarence Schmalz Cup Final once to compete for the All-Ontario Junior "C" title. In 1969, the Blades lost 4-games-to-3 to the Woodstock Navy-Vets. Oakville moved up to the Junior B level for the 1970-71 season, and joined the Mid-Ontario Junior B league. In 1971, the leagues realigned, and Oakville moved to the new Central Junior B league. In 1975 and 1991 the Blades made it the Sutherland Cup Final for the All-Ontario Junior "B" title. The first time, they were defeated by the Metro Junior B Hockey League's Bramalea Blues 4-games-to-3. The second time, they were defeated by the Midwestern Junior B Hockey League's Waterloo Siskins 4-games-to-0. Oakville became a Junior A team in the mid 1990s and ever since they played in the Ontario Junior Hockey League Buckland Cup Final five times, winning three Buckland Cups in franchise history.
2007-08 season
The Blades had a great 2007-08 regular season. With 39 wins, 6 losses, and 4 overtime losses, the Blades finished first overall in the West Division. After a bye in the division quarter-final, the Blades defeated the Milton Icehawks 4-games-to-1 in the division semi-final and Georgetown Raiders 4-games-to-1 to win the West Division playoff title. In the North/West Conference championship, the Blades took on the defending Royal Bank Cup 2007 champion Aurora Tigers. The Tigers appeared dominant, but faltered late in the series to lose to the Blades 4-games-to-2. In the OPJHL Buckland Cup final, Blades dominated the Markham Waxers and won 4-games-to-1 to win their first ever Junior A league championship.
The 2008 campaign got rocky when the Blades shipped off to Cornwall, Ontario for the Royal Bank Cup. Star goaltender Scott Greenham could not attend the tournament despite leading the Blades to the OPJHL and Central Canadian Championships. Having accepted a scholarship to play for the Alaska Nanooks,[1] he would lose his NCAA eligibility if he played in the Royal Bank Cup because his age (21).[2] With this, the Blades had to bring their back-up cold off the bench for the national championship. In the first game of the tournament, Oakville had to play the host Cornwall Colts of the Central Junior A Hockey League. Despite outshooting them, the Blades were shocked by the Colts 5-4. The next night, the Blades drew the Weeks Crushers of the Maritime Junior A Hockey League. The Blades badly outshot the Crushers, but the Crushers managed to squeak out a 4-3 overtime victory of the Central Canadian champions. In a nail-biting and high scoring outing, the Blades gave Humboldt a 7-6 loss to keep contention for a playoff spot in the tournament. It was not to be though, as the Blades out-shot but still lost to the top ranked Camrose Kodiaks 6-1.
Despite outshooting all four of their opponents, the Oakville Blades lost three out of four games and were eliminated on a head-to-head tie breaker with Weeks.
2018-2019 season
The Oakville Blades had their best season yet in franchise history, winning the OJHL, the Dudley-Hewitt Cup, and coming in third place going to the semi-finals at the National Jr. A Hockey Championship, the furthest they have got at the national tournament. The Blades finished with the highest wins ever, and tied for most points in club history.
