From a media release:

Shaftesbury announced today that production is now underway on Macy Murdoch (8×11), a new CBC Gem original tween series that follows the adventures of Detective William Murdoch’s time-travelling great-great-great-granddaughter. A spinoff of Shaftesbury and CBC’s hit long-running drama Murdoch Mysteries based on novels written by Maureen Jennings, the series is currently shooting in Toronto and will debut on CBC Gem in spring 2023.

Sixteen-year-old Macy is a forensic wunderkind who unravels a century-old mystery with the help of her two friends Zane and Billie. When a villain uses a time machine to frame famous Edwardian-era Detective William Murdoch for murder, Macy and her friends travel back in time to find the real perpetrator of the crime. Not only are the teens trying to crack a difficult case, but the trio are undercover, trying to solve a mystery in 1910 without the help of modern technology.

Macy Murdoch captures the playful, mystery-loving spirit of Murdoch Mysteries with Canadian Screen Award-winner Shailyn Pierre-Dixon (Pretty Hard Cases, The Book of Negroes) co-leading the series with Beau Han Bridge who plays Zane, and Raffa Virago as Billie. The series will have a special guest appearance by Spencer West, while Shanice Banton (“Mrs. Violet Hart”) and Lachlan Murdoch (“Constable Henry Higgins-Newsome”) from the beloved CBC series will appear in the series as guides to help the young detectives absolve Murdoch of a crime he did not commit.

The digital series is directed by Laurie Lynd with showrunner Jennifer Kassabian and Co-EP Robina Lord Stafford.  The series was initially developed by JP Larocque and Jessica Meya. For CBC, Sally Catto is General Manager, Entertainment, Factual and Sports; Marie McCann is Senior Director, Children’s Content, CBC Kids; and Lisa Cinelli is Executive in Charge of Production, Children’s and Youth Programming.
