‘Murdoch Mysteries’ Season 20 Release Date, Plot, Cast and Trailer as the Milestone Season Finally Escapes Toronto
Few shows can claim to have kept viewers guessing for nearly two decades, yet ‘Murdoch Mysteries’ keeps finding new corners of the past to explore. The Canadian period mystery premiered in January 2008 and has now reached a landmark twentieth season. The series has delivered more than 300 episodes along the way.
The headline change this time is geography, because the detective drama is leaving its Toronto comfort zone behind. With a stacked guest list and an international opening case, ‘Murdoch Mysteries’ looks ready to celebrate in style. Here is everything fans need to know before the first episode lands.
‘Murdoch Mysteries’ Season 20 Release Date and Where to Watch
The new season debuts on the CBC and the cable channel Ovation on Monday, October 5, 2026. TV Insider exclusively revealed the American premiere date, and Ovation TV will air the opener at 8 p.m. Eastern.
American viewers do not have to wait, since Ovation will air the show on the same day as its Canadian broadcast. In Canada, the season arrives on CBC Gem at 8 PM. Episodes will air weekly through May 2027, with the usual holiday breaks.
The season has 21 episodes, which matches the episode count of the previous season. That means plenty of room for the clever whodunits that have kept this show on the air for so long.
Ovation executive Sol Doten said the network is thrilled to bring American viewers this landmark season. After so many years, the warm welcome from a U.S. network says a lot about the show’s staying power.
The Season 20 Plot Takes Murdoch to Malta
The milestone premiere sends Murdoch on an unexpected international adventure when he diverts his travels to Malta, where mystery author Nigella Fletcher awaits execution for murdering her husband. The episode is titled The Maltese Falconer, and Murdoch questions the seemingly open and shut case.
Sally Lindsay guest stars as Fletcher. Her character plays an important role in the season premiere. CBC’s published photos also show Murdoch alongside an Inspector Lacroix, played by Marc Cabourdin.
Across the season, Murdoch and the Station House No. 4 team face personal and professional challenges, while tackling clever mysteries, groundbreaking inventions and sharp social commentary. The show is based on Maureen Jennings’ novels, and Jennings once again writes one episode this season.
Producers clearly see the Malta trip as a statement of intent. Shaftesbury chief Christina Jennings said the team has to keep surprising viewers by finding new places for Murdoch to go. Star Yannick Bisson has also teased that some of Murdoch’s archrivals will return.
Meet the ‘Murdoch Mysteries’ Cast Returning This Season
Yannick Bisson leads as Detective William Murdoch, joined by Thomas Craig as Inspector Brackenreid and Jonny Harris as Constable George Crabtree. That core trio has anchored the series for years, and fans would not have it any other way.
The wider ensemble includes Lachlan Murdoch as Henry Higgins, Kataem O’Connor, Daniel Maslany as Llewellyn Watts, Shanice Banton and Paul Sun-Hyung Lee. That deep bench keeps the station house feeling lived in, even when the case takes the detective abroad.

The guest list is just as eye catching. Dancing With the Stars professional Emma Slater, Jason Mewes of Jay and Silent Bob Strike Back, and Yanic Truesdale of Gilmore Girls are among the guest stars. It is a mix that only a show this confident could pull off.
One question lingers around Dr. Julia Ogden. Earlier reports said Helene Joy might return in a guest or recurring role. Cast listings for the new season still name her alongside Bisson. Exactly how much screen time she gets is something longtime fans will be watching closely.
‘Murdoch Mysteries’ Season 20 Trailer and Early Episodes
CBC has posted the official trailer on its season page, along with details on the plot, guest stars and historical references. An earlier first look trailer also appeared on YouTube. Both offer a taste of the globe trotting tone to come.
The first four episode titles give a sense of the variety on offer. Arcana Dei follows the murders of three French priests in a hotel, and Murdoch has to learn who they were protecting. The Big Smoke pits Murdoch against boxer Jack Johnson, who is implicated in the death of a man in his entourage.
A Date with Fate looks into the deaths of train crash survivors, and asks whether they are meeting a fate they escaped or being picked off by someone. That setup alone promises the kind of twisty puzzle fans expect.
Historical cameos remain a signature of the show. The series blends period drama and a steampunk look with light humor, and Murdoch has crossed paths with figures like Nikola Tesla, Alexander Graham Bell and Winston Churchill. With Murdoch finally trading Toronto for Malta and a boxing legend waiting in week three, which Nigella Fletcher twist or historical cameo are you hoping the season delivers first?
