The first season of Big Brother Canada began airing on February 27, 2013. Based on the worldwide franchise of the same name, it saw fifteen HouseGuests competing to win the show's grand prize. It is the first English adaption of the series to be held in Canada, although all seasons of the North American edition have been broadcast in the country. Arisa Cox served as the show's host during its ten-week run, concluding on May 2, 2013 when Jillian MacLaughlin was crowned the winner. The season proved to be a hit for Slice, significantly boosting the network's ratings and boosting traffic onto the official website.
