The third season of Big Brother Canada began airing on March 23, 2015. It featured sixteen HouseGuests, an increase from the prior two seasons. The series moved to Global Television Network with this season, previously airing on the smaller Slice channel. The move resulted in an increase in ratings, making it the highest rated season at the time; it has since been surpassed by the fourth season. The house featured a "steampunk" theme, while the season featured more twists than its predecessors. It is the first season to feature a triple eviction, a twist that has been used in later seasons. Lasting for a total of ten weeks, the season concluded on May 27 when Sarah Hanlon was named the winner.
