From a media release:

Shaftesbury announced today that #1 Canadian drama* MURDOCH MYSTERIES has begun production on Season 13, for CBC and UKTV, distributed by ITV STUDIOS Global Entertainment. With 18 new one-hour episodes, Season 13 will see the beloved series celebrate its 200th episode. Starring Yannick Bisson, Hélène Joy, Jonny Harris, and Thomas Craig, the internationally acclaimed series averaged 1.1 million viewers each week on CBC in Season 12,** and in the U.K. remains one of Alibi’s top-performing shows. MURDOCH MYSTERIES Season 13 will film on location in Ontario until November 2019, and premiere on CBC this fall, with international dates to follow.

With personal and professional changes for some of the Station House No. 4 team last year, Season 13 will continue to explore new developments in the lives of Detective William Murdoch (Bisson), Dr. Julia Ogden (Joy), Inspector Thomas Brackenreid (Craig), Constables George Crabtree (Harris) and Henry Higgins-Newsome (Lachlan Murdoch), and Detective Llewelyn Watts (Daniel Maslany) as they tackle Toronto’s toughest mysteries, from the serious and historic to the comical and unusual. Returning cast also include Shanice Banton, Arwen Humphreys, and Siobhan Murphy. Season 13 guest stars include Colm Feore (The Umbrella Academy, House of Cards) and Claire Goose (The Coroner, Casualty).

Yannick Bisson returns to the director’s chair for a Season 13 episode. Other episodes will be directed by showrunner Peter Mitchell, Harvey Crossland, Gary Harvey, Mars Horodyski, Sherren Lee, Mina Shum, and Craig David Wallace. Season 13 episodes are written by Mitchell, Paul Aitken, Noelle Girard, Maureen Jennings, Simon McNabb, Mary Pedersen, and Dan Trotta.

One of Canada’s most successful and longest-running dramas, MURDOCH MYSTERIES (13 seasons; 207 total episodes – 204 x one-hour episodes, 3 x two-hour specials) has become a staple for CBC and broadcasters around the world with its winning formula that brings together compelling mysteries, unique slices of turn-of-the-century history, ingenious inventions and personal moments for each character. The series is licensed to broadcasters in 150+ countries and territories including the U.S., U.K., France, Finland and China.

The MURDOCH MYSTERIES brand continues to grow and evolve – brand licensing deals include an all-ages immersive game experience, The Murdoch Mysteries Escape Series, a collaboration between Shaftesbury and Company & Co. that launched in early 2017 in Toronto, and recently relocated to historic Casa Loma in Toronto.

MURDOCH MYSTERIES is based on Maureen Jennings’s popular Detective Murdoch series of novels and premiered in Canada in January 2008.

MURDOCH MYSTERIES is executive produced by Christina Jennings, Scott Garvie, Yannick Bisson, Hélène Joy, and Peter Mitchell, who also serves as showrunner, and produced by Stephen Montgomery and Julie Lacey.
