Chad Rook, a Canadian actor with a notable presence in television and film, is set to join the cast of "My Life with the Walter Boys" for its third season. Rook will portray Mac, a drag racer who becomes a significant new character, introducing Cole Walter to the sport.

Rook's casting as a recurring guest star was announced in July 2025, with plans for him to appear in at least four episodes of the upcoming season. His character, Mac, makes his debut in the Season 3 premiere, "Homecoming." He is introduced when he brings a car to Tony's Automotive Shop, where Cole works. Tony mentions that Mac has been a long-time customer and a valued client due to the volume of vehicles he brings in for service.

Mac's passion for drag racing is evident as he describes the intense experience to Cole. He highlights the allure of "the speed, the crowd, the smell of the gas, the fact that you can die at any second," emphasizing that there is "nothing like it." This vivid description, coupled with an invitation to the track after his car, named Evangeline, is repaired, sparks Cole's interest in pursuing drag racing.

Rook is a familiar face to television audiences, with a career that includes credits on popular shows such as "Cedar Cove," "Supernatural," and "Virgin River." He also recently appeared in the film "Prank Wars" and is slated to appear in the new USA series "Anna Pigeon." His role in "My Life with the Walter Boys" adds to his diverse acting portfolio.

"My Life with the Walter Boys" continues to explore the dramatic storylines involving Jackie (Nikki Rodriguez), Cole (Noah LaLonde), and Alex (Ashby Gentry) as the series progresses into its third season.
