Fans of heartfelt small-town drama can’t get enough of Sullivan’s Crossing. That perfect mix of romance, family secrets, and those stunning Nova Scotia views keeps pulling people back to Timberlake. Season 3 wrapped up with a bombshell that left jaws on the floor—Maggie’s “summer fling” Liam showing up as her actual husband? Chaos. With production already underway, excitement is building for what’s next. Let’s dive into all the fresh details on Season 4, from when it’ll hit screens to who’s returning and the juicy plot threads dangling.
When Does Sullivan’s Crossing Season 4 Premiere?
Good news hit hard in July 2025 when The CW dropped the renewal announcement right before the Season 3 finale aired. CTV had greenlit it back in June, confirming the series’ staying power after topping charts on Netflix. No exact date has landed yet, but expect the premiere sometime in mid-2026—likely spring or summer, sticking to the show’s rhythm.
Filming kicked off in August 2025 in Halifax, Nova Scotia, with crews wrapping by November. Post-production will take a few months, but that timeline lines up perfectly for a 2026 debut.
Meet the Returning Cast: Familiar Faces and Exciting New Additions
The core crew that’s made Sullivan’s Crossing feel like home is back, bringing all the emotional depth fans crave. Morgan Kohan shines as Maggie Sullivan, the neurosurgeon navigating life back in her roots. Chad Michael Murray steps in as Cal Jones, the charming campground hand whose slow-burn romance with Maggie has hearts racing. Scott Patterson returns as Harry “Sully” Sullivan, the gruff-but-loving dad whose own love story added sweet layers last season.
Supporting stars keep the town alive too. Andrea Menard and Tom Jackson reprise Edna and Frank Cranebear, the wise locals whose bond grounds everything. Amalia Williamson as Lola Gunderson brings fresh energy to the friend group, while Lauren Hammersley, Allan Hawco, and others fill out the quirky ensemble. Tom Jackson’s Frank especially stole scenes with his quiet strength.
But here’s the buzz: Season 4 expands with four new series regulars, announced in late September 2025. Marcus Rosner, who teased trouble as Liam in the Season 3 finale, levels up to full-time—get ready for more fallout from that marriage reveal. Joining him are Fuad Ahmed (Late Bloomer), Jonathan Silverman (Good Girls), Colby Frost (The Oval Portrait), and Emerson MacNeil (We Were Liars). Details on their roles stay hush-hush, but whispers suggest they’ll stir up new conflicts at the Crossing. Showrunner Roma Roth calls it a “huge weight lifted” for the characters, hinting these newcomers will push boundaries.
Kohan’s Maggie has evolved so much—from city escapee to someone wrestling real purpose. Murray’s Cal? That easy smile hides depths fans adore. And Patterson’s Sully, off on a trip with new flame Helen (Kate Vernon), promises heartfelt returns. The cast’s chemistry feels effortless, like old friends catching up over coffee.
Sullivan’s Crossing Season 4 Potential Plot
Season 3 left the Crossing in knots. Maggie finally commits to her medical practice there, balancing career dreams with her bond to Cal after grieving their lost baby. Sully finds unexpected romance with writer Helen Culver, even planning a jaunt to Ireland. But then—bam—Liam Davies (Rosner) crashes the party, claiming he’s Maggie’s husband from a forgotten Vegas whim. Cal’s world crumbles just as things heat up. Showrunner Robyn Carr teases, “There’s never a dull moment at Sullivan’s Crossing.” That “big shoe drop” sets up a season of raw reckonings.
Expect Season 4 to unpack the marriage mess head-on. Maggie’s past catches up hard—will she and Cal weather the storm, or does Liam complicate their push-pull dynamic? Carr’s books marry them off early, but the show savors the tension, so fans might see more hurdles before any happily-ever-after. Sully’s absence opens doors for Maggie and Cal to lead the campground, but his return from Ireland could bring wisdom (or drama) from afar.
Side stories simmer too. Edna bounces back post-surgery, but rumors of her and Frank eyeing a move add bittersweet vibes. Antagonist Rob Shandon lurks, scheming against the Sullivans—his favors owed might backfire spectacularly. Lola’s new romance blooms, weaving in lighter moments amid the heartbreak. New cast like Ahmed and Silverman could introduce fresh faces to Timberlake, maybe rivals or allies shaking up the community. Carr promises “push and pull” in the romances, blending healing with those signature twists that make binge-watching addictive.
