The first look at season 4 of Sullivan’s Crossing hints at issues between Maggie and Cal after the arrival of her secret husband.
In a trailer released on Friday, February 6, Maggie (Morgan Kohan) says she was “finally in a good place” with Cal (Chad Michael Murray) before Liam (Marcus Rosner) arrived to Sullivan’s Crossing.
Maggie asks why Liam is there, to which he replies, “Can’t a husband pop in to check on his wife?”
Cal, meanwhile, questions why he didn’t know about Liam.

“I would have thought you would have mentioned being married before,” he mentions before another scene has Maggie discussing how she’s “happy now” with Cal.
Based on the book series by Robyn Carr, Sullivan’s Crossing follows neurosurgeon Maggie after she moves back home to rural Nova Scotia to reconnect with her estranged father, Sully (Scott Patterson). The brief getaway turns into Maggie making plans for a future in Sullivan’s Crossing with love interest Cal.
Season 3 of the hit series, which started streaming on Netflix in August 2025, threw a wrench in Maggie and Cal’s relationship just as they were getting to a good place. After arguing about whether Maggie was taking things too slow, they made plans to move in together — just as a new guest named Liam checked into Sullivan’s Crossing.
Liam then approached Maggie and revealed he was her husband, which came as a surprise to both Cal and Us. Showrunner Roma Roth later teased what viewers could expect from the show moving forward after the shocking reveal.
“I’m absolutely thrilled that Sullivan’s Crossing is returning for a fourth season,” Roth said in a statement after the finale aired. “Seeing it resonate with a global audience and watching the ratings climb have been a dream come true. Season 4 will explore themes of change and transformation so you can expect a whole new set of exciting and emotional challenges for Maggie and Cal.”
Kohan also shared her reaction to the twist.

“I remember hearing a little bit [about Liam early in season 3]. I didn’t know they were married,” Kohan told Swooon in July 2025. “There started to be talk when we filmed the scene with Lola and having summer flings. I knew that he was going to be coming into it, but I didn’t really know when or in what capacity. That cliffhanger was so much fun for me to read as well.”
Kohan acknowledged that Maggie’s trepidation about getting serious with Cal could have come from her past with Liam, adding, “I feel like it came up so last minute that I didn’t really have time to think about it, but I think it definitely would. It makes a lot more sense, for sure, for her to be more hesitant.”
The actress noted that she was just as in the dark about Liam’s role in season 4 as the audience.
“At the same time, I still don’t know the history, so who knows when we get to find out a bit more of that information, what he really means that he’s her husband and all that kind of stuff,” she continued. “I mean, there’s gonna have to be a few conversations had [between Maggie and Cal]. It’s going to be a trust thing to have to build up again because that is a pretty big thing to leave out.”
Sullivan’s Crossing is currently streaming on Netflix. Season 4 premieres on CTV and Crave Canada in spring 2026.
