From a media release:

After a breakthrough inaugural season, CTV announced today it has greenlit unprecedented second and third cycles of its hit new dramatic thriller, CARDINAL for broadcast in 2017/18. The order marks the first time CTV has ordered two consecutive seasons of a drama. Produced by Sienna Films and Entertainment One (eOne) in association with CTV, and commissioned for French-language Canadian broadcast by Super Écran, an additional two self-contained cycles, each consisting of six, one-hour episodes, have been ordered. Both series stars, Billy Campbell (THE KILLING) and Karine Vanasse (REVENGE), return for Seasons 2 and 3.

Cycles 2 and 3 will be filmed once again in Sudbury and North Bay and will be based on books in the John Cardinal Mysteries series written by Ontario native and award-winning author Giles Blunt. Season 2 will be shot this coming summer and is inspired by the third novel in the series, Black Fly Season. Set to shoot in Fall 2017, Season 3 is inspired by the 4^th and 5^thnovels in the series, By the Time You Read This and Crime Machine. As with the first cycle, each additional season will be a self-contained original adaptation inspired by the stories of each novel.

Season 1 has been licensed to BBC in the U.K., C More in Scandinavia and Calle 13 in Spain by eOne, and has several active negotiations underway.

Since its premiere in January, CARDINAL, a critical and ratings success, has averaged 1.2 million viewers, making it the most-watched new Canadian program of the 2016/17 broadcast season and the country’s most-watched original drama. Across all airings and on CTV and Super Écran, more than 3.6 million unique viewers watch episodes of CARDINAL weekly. Viewers looking to catch all of Season 1 thrills and chills can catch full episodes of CARDINALon CTV.ca, CTV GO, CraveTV^TM, and on CTV-branded VOD channels.

Cycle 1 of CARDINAL is adapted from the award-winning novel Forty Words for Sorrow, the first of Giles Blunt’s John Cardinal Mysteries, a series of six, best-selling Canadian crime novels. Starring Billy Campbell as Detective John Cardinal and Karine Vanasse as Detective Lise Delorme, Season 1 of the murder mystery was shot in Sudbury, Ont., North Bay, Ont., Atikameksheng Anishnawbek in Northern Ontario, and Toronto.
