Sullivan’s Crossing is officially headed into season 4, and the early signals point to big emotional shifts. Creator Roma Roth says the new chapter will lean into “change” and “transformation,” setting up fresh challenges for Maggie and Cal. Us Weekly reports that season 4 builds directly off the season 3 cliffhanger, so expect fallout from that final twist.

We also have a first look and a status update from the set. Deadline shared new images and confirmed filming began in August 2025 in Canada. Star Morgan Kohan called season 4 their “best yet,” which should ease fan nerves after that wild finale reveal.

Fan chatter hasn’t cooled either. For context, ScreenRant rounded up the show’s most debate-starting moments, including Maggie’s secret-husband shocker. Meanwhile, ShowSnob amplified Kohan’s bold “best yet” tease and noted the show’s summer 2025 surge after all three seasons hit Netflix.

Release Window & Where to Watch

Season 4 is expected in 2026. An exact date is not confirmed yet. Historically, new episodes premiere on CTV in Canada and then air on The CW in the U.S., with Netflix streaming following the completion of the season. If the pattern holds, fans can plan accordingly, but we’ll flag the date as soon as it’s confirmed.

Who’s Back in Sullivan’s Crossing Season 4

  • Morgan Kohan as Maggie Sullivan
  • Chad Michael Murray as Cal Jones
  • Scott Patterson as Harry “Sully” Sullivan

Additional regulars are expected to return, although full casting has not been announced. Deadline’s first-look suggests the core trio remains front and center.

Plot setup: That Secret-Husband Twist

The season 3 finale ended with a man claiming he’s Maggie’s husband. That gut-punch threatens Maggie and Cal’s fragile peace. Because season 4 is framed around “transformation,” expect the writers to test loyalties, expose old wounds, and force hard choices. ScreenRant’s fan-frustration list shows how quickly small choices escalate in this world, so the stakes feel real right away.

First Look, Trailer Status & Episode Count

Deadline’s gallery gives early vibes but holds back on spoilers. A full trailer hasn’t been released yet. Episode count is also unannounced; however, prior seasons ran ten episodes, and ShowSnob notes season 4 could follow suit. We’ll update once the network confirms the final number.

Why It Matters for Sullivan’s Crossing

This is an opportunity to expand the audience that discovered the show on Netflix in July and August 2025. The creative team is leaning into change, which often unlocks bigger arcs. If Maggie and Cal can weather the fallout, the show can push deeper into its small-town romance-plus-family-drama sweet spot.
