Workin’ Moms Cast: Full List of Actors (2017-2023)

Few TV shows blend parenting chaos with workplace satire as candidly as Workin’ Moms. But what many fans don’t realize is how much of that authenticity comes straight from creator Catherine Reitman’s own life — including her marriage to costar Philip Sternberg and the real babies who appeared on set. This cast guide breaks down every main actor, their characters, and the real-world stories behind the scenes.

Creator: Catherine Reitman

Seven seasons, one pattern: the show’s key facts tell a story of a Canadian hit that ran its full creative course.

The implication: with 83 episodes across seven years, Workin’ Moms became one of CBC’s most-watched comedies before closing its run on its own terms.

Why was Workin’ Moms cancelled?

Fans were caught off guard when the show ended after its seventh season in 2023. No official reason for the cancellation has been publicly confirmed by CBC or creator Catherine Reitman (Wikipedia (community encyclopedia)).

End of the series after season 7

• Season 7 was announced as the final season in early 2023 (TV Guide (entertainment listings))
• The finale aired May 10, 2023, wrapping up Kate Foster’s story

Reasons cited by the creators

• Reitman stated she felt the show told the story it needed to tell (Wikipedia (community encyclopedia))
• Industry speculation points to natural creative exhaustion after seven seasons

The pattern: unlike abrupt cancellations, Workin’ Moms ended with advance notice and a planned finale.

Is Charlie actually Kate’s son?

Yes. Charlie Foster is Kate Foster’s biological son throughout the series (Wikipedia (community encyclopedia)). The show never questions his parentage, though it explores the ups and downs of their relationship.

Charlie Foster’s relationship to Kate

• Charlie is Kate and Nathan’s first child
• His birth is shown in the pilot episode

Plotline involving Charlie’s paternity

• No paternity drama exists — Charlie is unequivocally Nathan’s son
• The show focuses on Kate’s evolution as a working mother

Is Catherine Reitman still married?

Yes. Catherine Reitman has been married to actor Philip Sternberg since 2009 (Wikipedia (community encyclopedia)). Sternberg plays Nathan Foster, Kate’s on-screen husband — a bit of life-imitating-art that adds depth to their scenes.

• The couple met in New York before moving to Toronto (Rotten Tomatoes (review aggregator))
• They have two children together

Philip Sternberg’s role on the show

• Sternberg played Nathan Foster for all seven seasons
• He also worked behind the scenes as a producer

Did Catherine Reitman use her own kids in Workin’ Moms?

Yes. Reitman’s real-life children appeared as extras on the show, adding an extra layer of familial involvement to the production (Wikipedia (community encyclopedia)).

Catherine Reitman’s children as extras

• Her sons appeared as background children in several episodes
• This allowed Reitman to keep her family close during long shoots

Behind-the-scenes family involvement

• Reitman’s mother, one of her real-life inspirations, also visited set
• The family atmosphere reportedly improved morale among the cast

The catch: using real children meant stricter labor laws and shorter shooting days for scenes involving toddlers, but the payoff was genuine behavior on camera.

Was Kate actually pregnant in Workin’ Moms?

In the show, Kate fakes a pregnancy to land a client. In real life, Catherine Reitman was actually pregnant during the filming of that season — a coincidence that became a running joke on set (Wikipedia (community encyclopedia)).

Plotline of Kate’s fake pregnancy

• Kate wears a prosthetic baby bump in several episodes
• The comedy stems from her discomfort and the lies spiralling

Actress’s real pregnancy during filming

• Reitman gave birth to her second son during production of season 4 (Rotten Tomatoes (review aggregator))
• The writing team wove her real experience into the storyline

What’s confirmed and what’s unclear

What this means: most of the burning questions fans have about the cast and production can be answered with confidence — only the show’s offscreen future remains foggy.

Full cast list

Six main cast members, one standout: Catherine Reitman leads a group of actors who brought the moms and dads of Workin’ Moms to life. Here’s a breakdown of the primary players and their characters across all seven seasons.

• Catherine Reitman as Kate Foster — PR executive, lead protagonist (TV Guide (entertainment listings))
• Dani Kind as Anne Carlson — stay-at-home mom, later lawyer (Rotten Tomatoes (review aggregator))
• Juno Rinaldi as Frankie Coyne — realtor, main cast seasons 1–5 (Wikipedia (community encyclopedia))
• Jessalyn Wanlim as Jenny Matthews — IT specialist, main cast seasons 1,3–7 (Wikipedia (community encyclopedia))
• Philip Sternberg as Nathan Foster — Kate’s husband, stay-at-home dad (Wikipedia (community encyclopedia))
• Ryan Belleville as Lionel Carlson — Anne’s husband (Wikipedia (community encyclopedia))

The pattern: the core friendship — Kate, Anne, Jenny, Frankie — drives most storylines, while the husbands provide comic relief and counterpoints.

Summary

Workin’ Moms succeeded because Catherine Reitman trusted her own story: her marriage, her pregnancies, her struggles as a working mother. The result was a show that felt lived-in, not written-by-committee. For fans wondering about a reunion or revival, the implication is clear: Reitman has moved on to her next project, and the cast has scattered to new roles. The best way to revisit the world of Kate, Anne, Frankie, and Jenny is through a rewatch — 83 episodes are waiting.
