All About Laysla De Oliveira's Partner: Bio, Career, and Relationship Facts
By Elena Rostova
Born in New York City before relocating to Toronto during his teenage years, Jonathan Keltz built his screen credentials across broad-spectrum North American productions. He honed his craft in Toronto theatre workshops and secured early guest spots on critically acclaimed series like Degrassi: The Next Generation and Cold Case.
His mainstream breakthrough arrived through HBO’s Entourage, where he appeared as Jake Steinberg, assistant to super-agent Ari Gold. Keltz then secured a career-defining anchor role on The CW’s royal drama Reign. Across four seasons and dozens of episodes, his portrayal of kitchen boy-turned-soldier Leith Bayard established him as a television mainstay capable of handling period dialogue, physical choreography, and romantic melodrama with equal ease.
Beyond historical drama, Keltz expanded into the procedural and romantic genres. He took on a prominent role in the Canadian crime series Cardinal, booked headlining parts in Hallmark and television romance films, and stepped behind the camera to develop narrative projects as a producer. That dual career trajectory gives both partners a clear-eyed understanding of the erratic working schedules, multi-month location shoots, and relentless audition cycles native to the entertainment trade.
