After months of anticipation, the wait is over for fans of the heartfelt romantic drama Sullivan’s Crossing. The highly anticipated Season 4 premieres on The CW on Monday, April 20, 2026, at 8:00 p.m. ET/PT, with Canadian viewers getting an earlier start on CTV beginning Sunday, March 22, 2026, at 8 p.m. ET/PT (streaming next day on Crave). The ten-episode season promises to deliver more emotional depth, small-town warmth, and romantic tension in the scenic setting of Timberlake, Nova Scotia. Netflix is expected to add the season later in 2026, likely late summer or early fall following the linear run.

Morgan Kohan returns as Dr. Maggie Sullivan, the driven neurosurgeon who left her high-pressure Boston life behind for a fresh start at her family’s outpost. Chad Michael Murray is back as Cal Jones, the charming yet complex local whose relationship with Maggie has become the emotional core of the series. Their chemistry continues to anchor the show as they navigate love, career choices, and the pull of the past.

The Shocking Revelation from Season 3’s Cliffhanger

Season 3 ended on a major bombshell that sets up the central conflict for Season 4. After Maggie and Cal finally committed to building a life together in Timberlake—with Maggie deciding to open her own general practice in town to balance her medical career with small-town living—her past came crashing back in the final moments.

During the grand opening celebration for Rob’s restaurant, Liam Davies (Marcus Rosner), a man Maggie had previously described as nothing more than a “summer fling,” suddenly appeared. In a jaw-dropping reveal, Liam introduced himself as Maggie’s husband. Cal stood stunned as the truth emerged: Maggie had a secret marriage she had never fully disclosed. The season cut to black on their shocked faces, leaving viewers desperate to know how this revelation would impact the couple’s hard-won future.

Season 4 picks up directly in the aftermath. Maggie’s life at the Crossing is finally taking shape with a renewed commitment to Cal and a new direction for her career. But Liam’s arrival—and the shocking details surrounding their marriage—threatens to upend everything. Cal, already sensitive about Maggie’s lingering attachment to her surgical career (highlighted in earlier episodes where he worried she might regret choosing him), now faces deeper doubts about trust, honesty, and whether Maggie can truly leave her past behind.

Show teasers describe the season as “pulling up MESSY,” with an old flame directly threatening the new future Maggie and Cal have started building. Fans can expect intense emotional conversations, jealousy, and difficult choices as Cal struggles to process the revelation while Maggie works to explain (and possibly resolve) her complicated history with Liam.

Notable Cast Changes and Returning Favorites

While the core couple remains front and center, Season 4 brings some changes to the ensemble. Scott Patterson (Sully) is not returning as a series regular after Season 3, with the story addressing his absence by having his character travel to Ireland. Showrunner Roma Roth has left the door open for a possible future return, but Maggie steps up to help run the Crossing in his absence.

Marcus Rosner joins as a series regular this season, bringing Liam fully into the mix as the disruptive ex-husband. Additional new series regulars include Fuad Ahmed, Jonathan Silverman, Colby Frost, and Emerson MacNeil, expanding the town’s dynamics with fresh faces and storylines.

Returning cast members include:

Tom Jackson as Frank Cranebear
Andrea Menard as Edna Cranebear
Amalia Williamson as Lola Gunderson
Lindura as Sydney Shandon
Dakota Taylor as Rafe
Reid Price as Rob Shandon

Guest stars such as Glen Gould, Cindy Sampson, and others will also appear, adding layers to the tight-knit community.

What to Expect in Season 4: Love, Growth, and Small-Town Challenges

Adapted from Robyn Carr’s bestselling novels, Sullivan’s Crossing has built a loyal audience with its blend of romance, family drama, medical elements, and the healing power of community. Season 4 continues exploring themes of second chances, forgiveness, and balancing personal ambitions with relationships.

Key story threads likely to unfold include:

Maggie and Cal’s rocky road: How will Cal handle the betrayal of Maggie’s hidden marriage? Can they rebuild trust, or will Liam’s presence create an unavoidable love triangle?
Maggie’s new practice: As she opens a general medical clinic in Timberlake, Maggie must prove she can thrive professionally without sacrificing her life at the Crossing.
Town dynamics and new conflicts: Fresh characters bring new energy, including potential business rivalries, personal secrets, and community events that test relationships.
Emotional growth: Both Maggie and Cal confront their insecurities—hers about vulnerability and his about feeling like a second choice—leading to heartfelt moments that define the season.

The official logline teases that Liam’s revelation “only upends Maggie’s life once again and causes Cal to question whether Maggie will ever truly be able to leave her past behind.” Expect plenty of “feels and heat” alongside the signature small-town charm that has made the series a comfort watch.
