Hexagon

, also known as the Purple Cobras, was an alliance on Big Brother Canada 3, consisting of Brittnee Blair, Johnny Colatruglio, Jordan Parhar, Kevin Martin, Sarah Hanlon, and Zach Oleynik.

Formed during Week 3, the alliance went on to win 8 of the 13 HoH's, 5 of the 12 PoV's, and the Coup d'Etat. Five of the six alliance members reached the jury stage. Two of the six alliance members reached the final four.

Due to winning so many competitions, the alliance ran the house for a little bit. However, as other houseguests began to catch onto the alliance, certain members were targeted and evicted. However, some managed to survive, and one went on to win the game.
