Big Brother (Quebec TV series)

The Numéro 1 (English: Number 1) was similar to the Head of Household position in the American version. Numéro 1 was exempt from eviction and enjoyed certain luxuries. They were also required to nominate two housemates for eviction.

The Numéro 2 (English: Number 2) was a unique feature to Big Brother Quebec. Numéro 2 was selected by Numéro 1. Despite being immune from eviction and enjoying certain luxuries, they were forced to sleep at the foot of Numéro 1's bed, lest they lose their power and privilege. In addition, Numéro 2 was required to choose a third housemate to nominate for eviction.

The Pouvoir de Véto (English: Power of Veto) worked similarly to the Power of Veto in the US, in that the winner could use it to save a nominee; however, unlike the American version, the Veto winner decided the replacement nominee. On occasion, there would be two Vetos available to win instead of the usual one, this would generally be weeks that the public voted to evict.

Food competitions were similar to the current Have and Have Not competitions in the US. The winners received desired food items, such as steak, bread, vegetables, and dairy, while the losers dined on slop.

Unlike most seasons of the American addition, three housemates faced eviction each week. On eviction nights, the three nominees were moved to a special room to hear the results of the vote, instead of sitting on designated chairs in the living room. Finally, all housemates except Numéro 1 voted to evict, unlike the US, where the two nominees cannot vote, and the Head of Household votes only in a tiebreaker situation. There were exceptions to this, however; the public on occasion had the opportunity to evict a housemate.

Used in other international formats like the Australian version, the "grenade" was used by the newly evicted housemate to throw at any housemate of their choice. The grenade had different powers and these powers changed every week.

The finale was completely different from the American version. Six housemates were in the house on the final day, unlike 2 or 3 in the American version. Unlike the jury format used in the American version to decide the winner, like the original format, the viewing public decided on the winner. However the former and current housemate get to vote on which finalist should not win.
