Production has begun on the fourth season of “Private Eyes”, with Global‘s hit detective series serving up more twist-filled, unpredictable cases for Private Investigators Matt Shade (Jason Priestley) and Angie Everett (Cindy Sampson) to solve.

“We’re so pleased to begin Season 4 of Global’s standout hit,” said Lisa Godfrey, Vice President of Original Content, Corus Entertainment. “After three incredibly successful seasons, ‘Private Eyes’ continues to resonate with audiences, and we are proud to support such a successful Canadian original scripted series.”

“We are ecstatic to continue our great partnership with Global on this popular series,” added Jocelyn Hamilton, eOne’s President, Canada, Television. “’Private Eyes’ has found a large and faithful audience around the globe, with Season 3 the current top-rated scripted series in Canada. We can’t wait to start filming and to share Season 4 with the fans.”

“With Toronto remaining a focal point of the series, Season 4 will showcase a range of different worlds from a Gatsby garden party, to a high-profile celebrity golf tournament, and the glitz and glamour of a film festival, to a bizarre alien cult,” reads the announcement for the new season. “Shade and Everett will be personally and professionally challenged as they think about the paths not taken, and what kind of life they want to lead.”

Returning characters this season include Jules Shade (Jordyn Negri), Don Shade (Barry Flatman), Zoe Chow (Samantha Wan), Officer Danica Powers (Ruth Goodwin), Nora Everett (Mimi Kuzyk) and Inspector Mathilda Carson (Linda Kash).

The fourth season will also welcome some new faces to the cast, including one familiar to ET Canada viewers: Canadian singer and ET Canada correspondent Keshia Chanté, who will be playing Mia, Angie’s friend.
