From a media release:

CTV announced today it has ordered a fourth instalment of its hit original crime drama MOTIVE (@MotiveTV) from Foundation Features and Lark Productions for the 2015/16 broadcast season. The announcement comes in advance of this weekend’s edge-of-your-seat Season 3 finale on Sunday, June 7 at 10 p.m. ET/PT on CTV and CTV GO. With an additional 13 one-hour episodes on order, bringing the series total to 52 episodes, Season 4 of the “whydunit” drama begins production this fall in Vancouver.

In addition to recently being nominated for a whopping 21 Leo Awards, MOTIVE was CTV’s top nominee for the 2015 Canadian Screen Awards, garnering nine nominations, including for Best Dramatic Series and for the Golden Screen Award for Best Drama/Comedy Series. With an average audience of 1.3 million viewers, MOTIVE is among the Top 3 most-watched Canadian dramas this season. With growth among viewers A18-34, Season 3 becomes the most-watched season yet for the demo.

This explosive season of MOTIVE followed Detective Angie Flynn (Kristin Lehman) and team as they brought another group of killers to justice, unlocking the motives behind each victim’s murder. Now, with just her investigation of Neville Montgomery (guest star Victor Garber, DC’S LEGENDS OF TOMORROW) left weighing on her mind and career, and those of her team — and her car bombed in plain view, there’s no denying there’s someone after Angie. Always an asset to her investigations, Detective Oscar Vega (Louis Ferreira) faces his own preoccupations, as he can no longer outrun the gravity of his looming health concerns, which proves a distraction for all.

In Sunday night’s powerhouse finale entitled “A Problem Like Maria” (Sunday, June 7 at 10 p.m. ET/PT on CTV and CTV GO), Detectives Angie Flynn, Oscar Vega, and Brian Lucas (Brendan Penny) are determined to prove that Neville Montgomery is behind the murder of Maria Snow (Luisa D’Oliveira, 50/50). Although all signs are pointing to Neville’s son, Robert Montgomery (Richard De Klerk, Repeaters) as the primary suspect, the team knows there must be something that will reveal the truth behind the events leading up to Maria’s death.

MOTIVE also stars Lauren Holly as the team’s lead medical examiner, Dr. Betty Rogers, and Warren Christie as Sergeant Mark Cross.

MOTIVE is produced by Foundation Features and Lark Productions in association with Bell Media. Executive Producers are Daniel Cerone (DEXTER, THE MENTALIST), Louise Clark (CORNER GAS, HIGH MOON), Rob Merilees (Capote, The Imaginarium of Dr. Parnassus), Erin Haskett (THE REAL HOUSEWIVES OF VANCOUVER), Rob LaBelle (MENTAL), Lindsay Macadam (Battle in Seattle), and Dennis Heaton (CALL ME FITZ, Fido), who continues to serve as Showrunner. Daniel Cerone is the series creator. The series is distributed internationally by NBC Universal International.
