The beloved Canadian sitcom, Son of a Critch, has officially secured its future on the air, much to the delight of fans worldwide. As of this current date in December 2025, the show has been officially renewed by CBC for a fifth season, with a concrete premiere window now set. This renewal confirms that the heartwarming and hilarious story of young Mark Critch navigating life in 1980s Newfoundland will continue, though the new season comes with a significant air of anticipation and speculation about its potential as a series finale.

The show, which is a fictionalized adaptation of creator Mark Critch's best-selling memoir, has resonated with audiences for its nostalgic charm, sharp wit, and deep emotional core. With the fourth season having wrapped up storylines around Mary’s mid-life crisis and Mike Sr.’s personal growth, the upcoming fifth installment is poised to explore new territory as young Mark continues his journey toward adulthood and, potentially, his eventual departure from St. John’s.

Son of a Critch Season 5: Official Renewal Status and Premiere Date

Fans no longer have to wonder about the fate of the Critch family.

• Renewal Status: Officially Renewed by CBC (Canadian Broadcasting Corporation).
• Official Release Window: Winter 2026.
• Episode Count: Season 5 is slated to have 12 episodes.

The Winter 2026 premiere date aligns with the show's typical release schedule, providing a clear timeline for when viewers can expect to catch up with Mark, his family, and his best friend, Ritche. The 12-episode order is a slight reduction from the 13 episodes of the fourth season, but promises a tightly focused narrative arc.

The Cast and Characters Expected to Return

The core ensemble cast that brings the Critch family and their world to life is expected to return, continuing their roles in the next chapter of the story. The chemistry among the main actors is a significant reason for the show's success, and their return is essential for Season 5.

Main Cast and Key Entities:

• Benjamin Evan Ainsworth as Mark Critch: The young, introspective protagonist whose life is the heart of the series. His journey through high school will be the central focus.
• Mark Critch as Mike Critch Sr.: The show's creator and narrator, playing his own father. Mike Sr.'s continued personal growth and relationship with his sons will be a key storyline.
• Claire Rankin as Mary Critch: Mark's mother, who was navigating a significant mid-life crisis in Season 4. Her "new era of personal growth," including potential travel and new friendships, is a major thread for Season 5.
• Malcolm McDowell as Patrick "Pop" Critch: Mark's wise and eccentric grandfather. His unique perspectives and relationship with young Mark are foundational to the show's charm.
• Colton Gobbo as Mike Critch Jr.: Mark's older brother, whose own coming-of-age stories provide counterpoint to Mark's.
• Sophia Powers as Ritche Perez: Mark's best friend and co-conspirator. The evolution of their friendship is crucial as they grow older.

The return of these central figures, particularly the dynamic trio of Mark, Mike Sr., and Pop, ensures the show will maintain its signature blend of comedy and heartfelt drama as it moves into the mid-to-late 1980s setting of St. John's, Newfoundland.

Plot Predictions: Is Season 5 the Final Chapter?

The most compelling speculation surrounding the fifth season is whether it will serve as the series finale. This curiosity is driven by the source material—Mark Critch’s memoir, which the show is based on.

The Memoir's Ending and Mark's Age

The original memoir concludes when Mark Critch is 18 years old, after he participates in a stage production of "Tomorrow Will Be Better." The series has been steadily moving through Mark's adolescence, and by Season 5, the character will be approaching that pivotal age. If the show adheres closely to the chronological conclusion of the book, Season 5 is a natural and logical point to wrap up the narrative.

The writers have a delicate balance to strike: concluding the story while Mark is still a "child" in the sense of his youth, but also showing his transition into a young adult. The Season 4 finale was reportedly written in a way that *could* have served as a series ending, which suggests the creative team is aware of the finite nature of the story. The 12-episode count could be designed to provide a focused, definitive conclusion to Mark's high school years and his life in Newfoundland before moving on to his career as a comedian and writer.

Key Storylines for the Fifth Season

Based on the end of Season 4, Season 5 is likely to explore several key themes and plotlines:

• The Critch Family Dynamics: Mary's journey of self-discovery following her mid-life crisis will continue, potentially leading to new, humorous, and challenging family situations. Mike Sr. will continue to grow, possibly facing the reality of his son, Mark, growing up and leaving home.
• Mark's Teenage Years: The series will delve deeper into the complexities of high school life in the 1980s, including more significant romantic relationships, academic pressures, and the pursuit of his burgeoning career in broadcasting or comedy. The show will continue to explore themes of identity and belonging.
• The Newfoundland Setting: The unique culture and landscape of St. John's, Newfoundland, will remain a central character, with the show continuing to use local references and historical context to ground the story. The nostalgic elements—from music to technology—will be even more pronounced as Mark gets older.
• The Death of a Student: Season 4 featured the sudden death of a fellow student, a serious moment that rattled young Mark. Season 5 may explore the lasting emotional impact of this event on Mark and his peers, adding depth to the show's comedic framework.

Whether it’s the final season or not, Son of a Critch Season 5 promises to be a powerful and moving chapter, bringing Mark closer to the end of his childhood and the beginning of his remarkable career.
