The official première date for the fourth season of Big Brother Canada has been set for Wednesday, March 2 at 9 ET/PT on Global TV. The designers have been working hard redesigning the big brother house with this seasons new theme. It will be exciting to see what design theme they come up with for this season as last season was regarded as one of the best designed big brother houses. The big brother Canada twitter account teased us with a photo (to the right) showing they’ve been hard at work redesigning the house for the new cast.
