Bytown Boys Supporters Club was founded in April 2011, in response to news of an expansion Canadian Soccer League (CSL) franchise being awarded to the city of Ottawa. During their inaugural season with Capital City F.C. in CSL, the Bytown Boys generated a level of excitement and energy which rivaled the strongest supported teams in the league. This resulted in players, coaches, and the team itself offering praise to the supporters club, with team members such as Clint Irwin, Sullivan Silva, Kenny Caceros, Julien Edwards, Joel Bagby, and Shaun Harris commenting on the importance of the group in contributing to the home field advantage which saw Capital City play through an impressive inaugural season, culminating in an appearance at the final of the 2011 CSL season. On March 23, 2012, Capital City announced it would not field a team for the following Canadian Soccer League season, leaving the Bytown Boys without a club to support.
The sudden adjournment of Capital City put the future of the supporters club in question. In April 2012, however, it was announced that the group had reached an agreement with the Ottawa Fury, an organization which features a PDL club with NASL expansion on the horizon. During the 2012 PDL season, BBSC aided the Fury as they looked to continue the historical dominance they exert on their home pitch at Algonquin College Soccer Complex. This was a largely successful season for both the soccer club and the supporters group, with the Fury reaching the PDL Conference Semifinals.
