From the league's inception in 2001 through 2005, the Cannons were in the American Division. With the MLL contraction for the 2009 season from 10 to 6 teams (due to the state of the U.S. economy), there is currently only one division/conference. Boston has qualified for the MLL playoffs 2001, 2002, 2003, 2004, 2005, 2006, 2009, 2010, 2011, 2012 and 2015.
The Cannons won the 2004 and 2005 American Division championships. The Cannons won their first MLL Championship in 2011 defeating the Hamilton Nationals 10-9.
