Fans of the show did their part to ensure that Killjoys Season 4 will happen. “Bless the fans for everything they’re doing,” praises Michelle Lovretta. “Our numbers are going up every week, which is really, really hard in a season 3, so thank you. Keep that up!”[1]

Renewal of Killjoys for Season 4 and Season 5 was announced September 1, 2017. Like the previous seasons, they will each have ten episodes.[2]


Syfy announced that Killjoys season 4 will premiere on July 20, 2018.[3]


Production on Season 4 began on February 2, 2018. Adam Barken, who has been a writer and producer on the series since season one, is promoted to executive producer and showrunner for Killjoys.

“We are thrilled to have 20 episodes to complete the epic story of Killjoys,” said David Fortier and Ivan Schneeberg, executive producers of Killjoys and co-presidents of Boat Rocker Studios. “Michelle created a unique show that set a new standard for being both fun and empowering, and we are excited to see Adam taking the reins."[4][5]

Potential Crossover with Dark MatterEdit

Viewers have often associated Killjoys with its neighboring Friday space drama, Dark Matter[6], and the question of a crossover has been raised more than once. “I love [Dark Matter executive producer, Joseph Mallozzi], and we’re usually emailing each other, and we’ve certainly poked at the thought of it,” Michelle Lovretta admits. “I think that’s really contingent upon us first of all getting season 4 renewals, both of us… and then if we both get season 4’s, it then comes down to scheduling… if we were able to figure out enough in advance where we could have a credible crossover, I would totally be doing that, yeah.[7]
