The reality show that made backstabbing and showmances a TV art form is back, with season three of Big Brother Canada premiering on Global next Monday.

Over the next three days, ET Canada will reveal the 16 houseguests, kicking off tonight with a quarterback, a rock climber and a plus-sized model.

So just how far are the new houseguests willing to go in order to emerge this season’s Big Brother Canada winner?

“I don’t want to have to do it,” says contestant Brittnee of lying and stabbing her fellow houseguests in the back. Then again, she admits that plan “is crazy because this is Big Brother Canada. But you know, we’ll see.”

Contestant Zach says he’s planning to go all out… within limits. “I’m gonna do what I have to do,” he says, “what I have to do to get further in the game. But at the same time, there’s a certain line that I don’t want to cross.”

What about showmances this season? None of the newbies are ruling out the possibility, and Brittnee explains what she’s looking for in a showmantic partner. “I don’t like high-maintenance people,” she says, “or people that just think they’re better than everybody else.”

Houseguest Ashleigh admits that “it’s definitely hard for me to stay nice” when she encounters obvious rudeness, so watch out for fireworks if any of her fellow houseguests are “obnoxious, in-your-face people.”

In that regard, her fellow houseguest Bobby might just fit the bill. “I would define myself as crazy, fun-loving, spontaneous,” he says. “Some people might think I’m borderline psychotic,” he adds with a laugh.

Tune in to ET Canada over the next three days, airing weeknights at 7:30 p.m. ET/PT on Global, to meet the houseguests from season three of Big Brother Canada.
