Tracing the professional trajectory of Amalia Williamson reveals a career built on a diverse range of genres, spanning from high-stakes family dramas to unsettling dystopian thrillers. Since her debut in the mid-2010s, the Canadian actress has moved from local theater roots in Oakville, Ontario, to becoming a familiar face on major international streaming platforms and television networks. Her filmography serves as a testament to her versatility, showing a steady progression from supporting roles in cult comedies to lead performances in prime-time dramas. As of 2026, her presence in the industry continues to expand with new projects that showcase both her acting range and her behind-the-scenes creative capabilities.

The Breakthrough in Television Drama

Television has been the primary vehicle for Williamson’s rise to prominence. Her work in long-form narratives allowed for the development of complex characters that resonate with a global audience, particularly within the "family drama" and "small-town mystery" niches.

Sullivan's Crossing (2023–Present)

One of the most significant pillars of her career is her recurring role as Lola Gunderson in Sullivan's Crossing. Based on the popular novel series by Robyn Carr, this show has become a staple for fans of heartfelt, character-driven storytelling. The series follows neurosurgeon Maggie Sullivan as she returns to her childhood home in Nova Scotia, navigating past traumas and current complications.

Williamson’s portrayal of Lola Gunderson provides a crucial layer to the show's ensemble. Lola is a character often caught between the historical secrets of the town and her own personal growth. Throughout the seasons, extending into the current 2026 broadcasts, Lola has evolved from a secondary presence into a character with significant narrative weight. The show's success on networks like CTV in Canada and The CW in the United States has solidified Williamson’s standing in the North American television landscape.

Northern Rescue (2019)

Before the success of Sullivan's Crossing, Amalia Williamson landed her first prime-time lead role in the CBC/Netflix original series Northern Rescue. Playing Maddie West, the eldest daughter of a family grappling with the sudden loss of their matriarch, Williamson delivered a performance that anchored much of the show’s emotional stakes.

The character of Maddie West is complex—a teenager dealing with grief while forced into a maternal role for her younger siblings. The series explores themes of healing and resilience as the family moves from the city to a small northern town to run a search-and-rescue service. Williamson’s ability to portray the "moody yet responsible" eldest child helped the show gain a dedicated following during its release. The dynamics between her character and her father, played by William Baldwin, were central to the narrative, highlighting her capacity to hold her own alongside established industry veterans.

Exploring the Thriller and Horror Genres

Beyond the realm of family drama, Williamson has demonstrated a keen interest in darker, more suspenseful material. Her film work often leans into the psychological and the dystopian, offering a sharp contrast to her television roles.

Level 16 (2018)

In the 2018 cult hit Level 16, Williamson played the role of Rita. The film is a chilling dystopian thriller set in a windowless boarding school where girls are raised to follow strict rules of cleanliness and etiquette. The narrative slowly unravels a horrifying truth about the institution's real purpose. As Rita, Williamson contributed to the tense, claustrophobic atmosphere of the film. Level 16 received critical acclaim for its atmosphere and social commentary, and it remains one of the most notable entries in her early filmography, showcasing her ability to fit into high-concept independent cinema.

The Kid Detective (2020)

Another significant cinematic entry is The Kid Detective, starring Adam Brody. Williamson appeared as Melody in this dark comedy-mystery that subverts the "boy detective" trope. The film follows a once-celebrated child detective who is now a struggling adult solving trivial cases until a serious murder investigation lands on his desk. While her role was part of a larger ensemble, the film’s critical success and its unique tone allowed Williamson to be part of a project that blended sharp humor with genuine pathos.

Suspense and Lifetime Original Movies

Williamson has also become a frequent presence in the thriller sub-genre often associated with television movies. These projects typically involve high-stakes domestic drama and psychological tension.

  • Glass Houses (2020): In this thriller, she played Blair, a character involved in a web of neighborhood secrets and revenge. The plot follows a babysitter who seeks to expose the dark side of a seemingly perfect family, only to find herself in a dangerous game of cat and mouse.
  • Remember Me, Mommy? (2020): Also known as The Secret of My Neighbor, this film saw Williamson in the role of Janie Wade. The story centers on the discovery of long-held family secrets and the tension that arises when a biological daughter reappears under unexpected circumstances.
  • My Sister's Double Life (2025): One of her more recent ventures in this genre, where she took on the role of Hayley Ellis. These roles have allowed her to explore characters driven by desperation, mystery, and survival, further diversifying her acting portfolio.

Comedic Roles and Guest Appearances

Williamson’s range extends into comedy, where she has appeared in some of Canada’s most successful exports. Her ability to adapt to different comedic styles—from the fast-paced wit of Letterkenny to the grounded humor of family life—demonstrates her adaptability.

Letterkenny (2016–2023)

In the acclaimed series Letterkenny, Williamson played the role of Harley. Known for its rapid-fire dialogue and unique linguistic quirks, Letterkenny is a difficult show for any actor to step into without a strong sense of timing. Her involvement in the series, particularly in later seasons, connected her with a massive international fanbase that follows the residents of the fictional rural community.

Bria Mack Gets a Life (2023)

In the series Bria Mack Gets a Life, she played Gemma. This show offers a stylized look at the life of a young Black woman navigating adulthood with the help (and hindrance) of a vivid imaginary friend. Williamson’s role in this production highlights her involvement in contemporary, socially conscious television that uses humor to explore identity and growth.

Children Ruin Everything (2022–2023)

Further showcasing her comedic timing, Williamson appeared as "Bubblegum" in the series Children Ruin Everything. This show, which explores the chaotic reality of parenting in the modern world, allowed her to play a role that contrasted with the more serious, drama-heavy characters she is often known for.

Recent Developments and 2026 Projects

As of April 2026, Amalia Williamson remains highly active, with her career trajectory pointing toward more leading roles and creative control. The industry has seen her transition from being a "rising star" to an established professional with a multi-hyphenate skillset.

You’re Killing Me (2026)

Her most recent project, You’re Killing Me, features her in the role of Andrea Walker. This series continues her trend of working in projects that blend tension with modern character dynamics. Early reports and production notes suggest that this role is one of her most mature to date, allowing her to lean into her experience with suspense while maintaining the emotional groundedness that made her successful in Northern Rescue.

The Truth Fairy (2025/2026)

In addition to her acting work, Williamson has been increasingly involved in the production of short films. The Truth Fairy is a project where she is credited not just as a performer (Veruca), but it also represents the continuation of her interest in directing and writing. Throughout her career, she has consistently expressed a desire to tell her own stories, a goal supported by her film and television production degree from Sheridan College.

The Multi-Hyphenate: Writing and Directing

While the public primarily knows her through her movies and TV shows as an actress, Williamson has a significant body of work as a creator. Understanding this aspect of her career provides a more complete picture of her professional identity. Between 2016 and 2025, she has directed and written several short films, including:

  • Daughter (2017): Writer and Director.
  • Rosie (2018): Writer and Director.
  • Love Not Lost (2019): Writer and Director.
  • I Am Here (2019): Director.
  • Blue Light (2016): Director.

These projects often explore intimate, human-centric themes, suggesting that her future in the industry may involve a move toward producing or directing full-length features. This dual focus on being in front of the camera and behind it is a hallmark of many successful modern artists, allowing her a deeper understanding of the mechanics of storytelling.

Career Trajectory and Industry Impact

Amalia Williamson’s filmography reflects the changing landscape of Canadian media. By taking roles in shows that are co-produced by domestic networks (CBC, CTV) and international giants (Netflix, The CW), she has benefited from the "globalization" of local content. This has allowed her work to reach audiences in dozens of countries simultaneously, a feat that was much harder for previous generations of Canadian actors.

Her choice of roles suggests a deliberate attempt to avoid being typecast. Transitioning from the gritty, survivalist atmosphere of Level 16 to the lighthearted chaos of Children Ruin Everything requires a high degree of technical skill. Furthermore, her background in theater and formal film production education has given her a reputation for being a "director's actor"—someone who understands the technical needs of a set as much as the emotional needs of a scene.

As the industry moves through 2026, Williamson is increasingly viewed as a reliable lead capable of carrying a series. Her work in Sullivan's Crossing continues to be a highlight for many viewers, especially as the show enters its newest chapters. The combination of her acting credits and her growing list of directorial projects suggests that she will remain a significant figure in the entertainment industry for years to come.

Whether you are revisiting her breakout performance in Northern Rescue or catching up with her latest work in You're Killing Me, Williamson's filmography offers a wide array of stories to explore. Her career serves as a roadmap for modern performers who utilize every tool at their disposal—acting, writing, and directing—to build a lasting and meaningful presence in the world of cinema and television.
