Canada’s longest-running and most-watched period mystery series, Murdoch Mysteries, is gearing up to make its big return to the Canadian airwaves this fall for its 18th season in 2024. This beloved series has never been shy about adapting to the times, keeping things fresh while staying true to its roots as a period drama—even as society pushes for more modern representation. One thing that keeps die-hard fans glued to their screens is the fact that, unlike many long-running shows, the core cast of four has stuck around for almost two decades. It gives folks across the country a real sense of having grown up alongside them.
“We are delighted that Paul has joined us in the world of Murdoch,” says Executive Producer Peter Mitchell. “Paul brings a wealth of experience to his role as Inspector Albert Choi and we think the fans will enjoy seeing him on the team at Station House 4.”

When Murdoch Mysteries first hit the airwaves back in 2008, with episodes largely adapting Maureen Jennings’ Detective Murdoch novels, it looked a lot like most period dramas of the time—an all-white cast. But as the show has evolved, so has its approach to representation. Season 18 is shaking things up with the addition of Kim’s Convenience star Paul Sun-Hyung Lee, making his debut as the first major character to join the show in a while. He steps into the role of Inspector Albert Choi, the new boss at Station House #4. As always, Yannick Bisson continues to lead the charge as Detective William Murdoch, joined by Hélène Joy as Dr. Julia Ogden, Thomas Craig as Inspector Thomas Brackenreid, and Jonny Harris as Constable George Crabtree.
What to expect in Murdoch Mysteries Season 18 with Lee’s Debut
Murdoch Mysteries is set in Toronto in the early 1900s, during the age of invention, where Detective William Murdoch enlists innovative forensic techniques to solve some of the city’s most perplexing murders. Season 18 is full of ‘Murdochian’ delights: a murder at a Charles Dickens convention; Murdoch acting as a bodyguard for a silent film star and thrown into a cinematic adventure himself; foiling a theft of the world’s largest ruby; proving the veracity of a “Missing Link” skull found in Milton, Ontario; and a holiday episode celebrating the “misfits” and singletons. Episodes that root mysteries in the social issues of the time are also explored: a worker’s strike at a factory; an early instance of low-income housing; competing public hydro projects; and immigrants trying to purchase land in the ‘paradise’ of the wilds of Canada. Finally, the milestone 300th episode will feature Detective Murdoch visiting the UK to see his wife, Dr. Julia Ogden, as they celebrate their wedding anniversary.
Fans down south in the U.S. won’t be left out for long either, with the new season expected to hit Acorn TV and Ovation by February 2025. It’s a true testament to Canadian television’s staying power, eh?
