　　Big Brother 3 is the third season of the Canadian reality television series Big Brother Canada. It is based upon the Netherlands series of the same name, which gained notoriety in 1999 and 2000. The series premiered on Global on March 23, 2015 and will last for ten weeks. The series revolves around sixteen strangers living in a house together with no communication with the outside world. They are constantly filmed during their time in the house, and are not permitted to communicate with those filming them. One HouseGuest, known as the Head of Household, has the task of nominating two of their fellow HouseGuests for eviction. The Power of Veto can be used to save a nominee. The HouseGuests then vote to evict one of the nominees, with the HouseGuest who receives the most votes being evicted from the house. When only two HouseGuests remained, the previously evicted HouseGuests decide which of them would win the $100,000 grand prize.收起
