Sullivan's Crossing' Casts 4 New Series Regulars For Season 4

The next chapter of Sullivan’s Crossing Season 4 is already stirring fans with fresh drama, romantic tension, and pivotal decisions ahead. As the series prepares for its U.S. premiere on The CW on Monday, April 20, 2026, at 8/7c, excitement is building around the core trio—though one major change has shaken the fanbase.

Morgan Kohan returns as the resilient neurosurgeon Maggie Sullivan, Chad Michael Murray reprises his role as the charming Cal Jones, and while Scott Patterson‘s Harry “Sully” Sullivan was a cornerstone of the show, he will not appear in Season 4. Recent reports confirm Patterson’s exit stems from creative differences that became “untenable,” with the actor issuing a statement emphasizing that fans “deserved better” and clarifying he chose to step away rather than being dropped.

Showrunner Roma Roth has explained that Season 4 picks up immediately after Season 3’s finale, with Sully still in Ireland supporting his partner Helen. The door remains open for potential future returns, but his absence shifts the focus squarely onto Maggie and her evolving life at the Crossing.

Premiere Details and Streaming Outlook

In Canada, the season launched earlier on CTV starting Sunday, March 22, 2026, at 8 p.m. ET/PT, with episodes available the next day on Crave. Trailers and first-look footage dropped in early March, teasing steamy moments and emotional confrontations.

For U.S. viewers on The CW, the 10-episode run begins April 20, marking a slot change from previous Wednesday airings to Mondays. Internationally, Netflix—where the series exploded in popularity—will likely add Season 4 post-broadcast, continuing its strong performance as a feel-good romantic drama akin to Virgin River.

The official logline promises Maggie’s life “finally taking shape” with a new career direction and renewed commitment to Cal. Yet, early plot hints center on a major crossroads: Will Maggie fully embrace the serene, community-focused life at Sullivan’s Crossing, or will lingering ties to her high-powered Boston past pull her away?

The Central Dilemma: Maggie’s Choice Between Boston and the Crossing

Season 3 wrapped with Maggie committing to open a local medical practice in Nova Scotia after performing life-saving surgery and solidifying her bond with Cal. She appeared ready to leave her old life behind—until Liam Davies (Marcus Rosner) arrived, revealing he is her secret husband from a past relationship.

This bombshell has fueled intense speculation. Trailers show heated arguments between Maggie and Cal over the undisclosed marriage, with Liam pushing for a second chance. The dynamic creates a classic love triangle, forcing Maggie to confront trust issues, past mistakes, and what she truly wants.

Insiders and teasers suggest Maggie faces a defining choice: stay rooted in the Crossing’s tight-knit community, pursue her new practice, and build a future with Cal—or revisit Boston’s demands, perhaps tied to unresolved professional or personal loose ends. The absence of Sully amplifies this, as Maggie must navigate without her father’s guidance, leaning more on Cal, friends like Frank (Tom Jackson) and Edna (Andrea Menard), and the town’s support.

Themes of redemption, forgiveness, and second chances remain central, with the scenic Nova Scotia backdrop providing emotional contrast to the turmoil.
