Britannia is predominately an AA school in terms of athletics according to the
BC School Sports. The school had a dominant football team in the 1970s, winning the
Shrine Bowl Provincial Championships once, and being runners-up three times. In 1974, Britannia hosted their first basketball tournament called the Bruin Invitational Basketball Tournament. Since then, the tournament is hosted annually and it has been a great success to Britannia. On March 8, 2008, The Britannia Senior Boys Basketball team won the British Columbia AA Provincial Basketball Tournament by beating the
Windsor Dukes 81-73. That was the first time any public school from East Vancouver has won a B.C. boys senior high basketball title. The next season, Britannia's senior boys team made the 'AA' Provincial final again, but lost to
Southern Okanagan Secondary School from Oliver. The following 2010 basketball season saw the Britannia Senior Boys Basketball team return to the AA Provincial Basketball final and defeated the basketball team from
RC Palmer Secondary to reclaim the title of AA Provincial Champion. On March 10, 2012, the Britannia Senior Girls Basketball team also made school history by capturing its first B.C. girls basketball title after a silver medal finish the year before in 2011. Britannia's senior girls team beat Lambrick Park 69-61 in the AA Provincial basketball final after a fourth quarter surge that saw the Bruins outscore the Pride 21-4.
