Sullivan’s Crossing Season 4: Release Date, Plot, Cast, and the Game-Changing Twist

Sullivan’s Crossing, the beloved Canadian romantic drama, has fans eagerly awaiting its fourth season after a jaw-dropping Season 3 finale. With its intoxicating blend of romance, drama, and the stunning natural beauty of Nova Scotia, the show has skyrocketed to the top of Netflix charts, drawing comparisons to Virgin River. The CW and CTV confirmed Season 4’s renewal in June 2025, and as production gears up, one shocking detail from the Season 3 finale is set to change everything for Maggie Sullivan and the residents of Timberlake. Here’s everything we know about Sullivan’s Crossing Season 4, from its release date to the cast, plot, and the twist that has fans buzzing.

Release Date: When to Expect Season 4

While no exact premiere date has been announced, Sullivan’s Crossing Season 4 is slated to debut on CTV in Canada around April or May 2026, with The CW in the U.S. following shortly after, likely in June 2026, based on the show’s consistent annual release pattern. Production is set to begin in Halifax, Nova Scotia, from August 7 to November 25, 2025, supporting a spring premiere timeline. Netflix, which has propelled the show’s global popularity, is expected to release Season 4 in August 2026, following the pattern of Season 3’s August 11, 2025, drop. The season will consist of 10 episodes, continuing the format of previous seasons. Fans can catch up on Seasons 1-3 on Netflix or stream Season 3 for free on The CW app until the new season arrives.

Plot: A New Chapter in Timberlake

Season 4 picks up after the explosive Season 3 finale, which aired on June 22, 2025, and left fans reeling with a cliffhanger. Maggie Sullivan (Morgan Kohan), having decided to stay in Timberlake to open her own medical practice, was blindsided by the arrival of Liam (Marcus Rosner), a man from her past who claimed to be her husband. This revelation, described by fans on X as leaving them “yelling at their screens,” sets the stage for a season filled with emotional turmoil, romantic entanglements, and the serene yet dramatic backdrop of Timberlake’s campground.

The central focus will be Maggie’s relationship with Cal Jones (Chad Michael Murray), which faces its greatest test yet. Liam’s claim threatens to unravel their slow-burn romance, raising questions about trust and Maggie’s past. Was their marriage a fleeting moment, perhaps a forgotten Vegas escapade, or is there more to the story? Morgan Kohan hinted in an interview with Swooon that “a few conversations” will be needed to rebuild trust, suggesting a deep dive into Maggie’s emotional and legal complications. The show may explore whether Maggie and Cal can overcome this hurdle or if Liam’s presence will spark new romantic tensions.

Beyond Maggie’s love triangle, Season 4 will delve into other relationships. Sully (Scott Patterson), Maggie’s father, agreed to travel to Ireland with Helen (Kate Vernon), marking a significant shift. His absence could leave the campground’s future in Maggie’s hands, with potential threats like financial struggles or “shady new neighbors” challenging the community. Edna Cranebear’s (Andrea Menard) recovery from brain tumor surgery, performed by Maggie, will highlight themes of healing and togetherness, while Frank Cranebear (Tom Jackson) supports her. Other storylines include Rafe (Dakota Taylor) and Sydney’s (Lindura) potential breakup over differing views on marriage, and Lola (Amalia Williamson) and Jacob’s (Joel Oulette) long-distance challenges after Jacob’s return to Alberta.

The show’s signature blend of small-town drama, emotional depth, and stunning Nova Scotia scenery—filmed in Halifax with its misty shores and lush forests—will amplify the stakes. Expect heartfelt moments by the campfire, tense confrontations under starlit skies, and the serene landscapes that make Timberlake a haven for romance and redemption.

Cast: Who’s Returning and New Faces

The core cast of Sullivan’s Crossing is expected to return, maintaining the show’s tight-knit ensemble. Confirmed returning actors include:

Morgan Kohan as Maggie Sullivan, the neurosurgeon navigating love and her new life in Timberlake.

Chad Michael Murray as Cal Jones, Maggie’s love interest facing the fallout of Liam’s arrival.

Scott Patterson as Harry “Sully” Sullivan, Maggie’s father, whose journey to Ireland may shift his role.

Andrea Menard as Edna Cranebear, recovering from surgery and a pillar of the community.

Tom Jackson as Frank Cranebear, Edna’s supportive husband.

Lindura as Sydney Shandon, whose relationship with Rafe is at a crossroads.

Reid Price as Rob Shandon, rebuilding his life post-diner fire with girlfriend Jane.

Dakota Taylor as Rafe Vadas, grappling with his desire for marriage.

Amalia Williamson as Lola Gunderson, facing long-distance love with Jacob.

Cindy Sampson as Jane, Rob’s girlfriend and a new fixture in Timberlake.

Kate Vernon as Helen Culver, Sully’s romantic partner with plans for Ireland.

Marcus Rosner’s Liam, introduced in the Season 3 finale, is expected to have a significant role, given his game-changing claim. New guest stars may join, following the precedent of Season 3 additions like Cooper (Steve Lund) and Jacob Cranebear (Joel Oulette). While no major cast exits are confirmed, Sully’s trip to Ireland raises questions about Scott Patterson’s screen time, though a time jump could bring him back to Timberlake.

The Detail That Changes Everything

The bombshell that Maggie has a secret husband in Liam is the detail that will reshape Sullivan’s Crossing Season 4. This twist, revealed in the final moments of Season 3, stunned Cal, Sully, and even Maggie herself, suggesting she may not have realized the marriage was still valid. As Kohan noted in Swooon, this omission is “a pretty big thing to leave out,” setting up a trust crisis that could fracture Maggie and Cal’s relationship. The show may explore whether the marriage was a youthful mistake, a legal oversight, or something more sinister, with Liam’s true intentions unclear. This revelation not only threatens Maggie’s romance but also her plans to root herself in Timberlake, as legal and emotional fallout could pull her back to her past. Fans on X have called it a “game-changer,” with one post noting, “Maggie’s got a husband now? What?!” This twist promises to drive Season 4’s drama, making it a pivotal moment for the series.

Why Season 4 Is a Must-Watch

Sullivan’s Crossing Season 4 is shaping up to be its most dramatic yet, with Liam’s arrival shaking the foundations of Maggie’s life. The romance between Maggie and Cal, set against Timberlake’s breathtaking landscapes, will keep fans swooning, while the community’s struggles—Edna’s recovery, Sully’s journey, and the campground’s future—add emotional depth. Filming in Halifax ensures more stunning visuals, from coastal cliffs to tranquil forests, making it the perfect summer escape. With production starting soon and a Netflix release expected in August 2026, clear your calendar for a season of love, secrets, and the cozy charm of Timberlake.
