Season 4 of Sullivan’s Crossing will be picking up the pieces after Cal met Maggie’s secret husband — but who else is expected to appear?

Based on the book series by Robyn Carr, Sullivan’s Crossing centers around neurosurgeon Maggie (Morgan Kohan) 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 (Chad Michael Murray).

Season 3 of the hit series, which started streaming on Netflix in August 2025, initially showed cracks in Maggie and Cal’s relationship when he wanted to take the next step but she didn’t. Elsewhere in the show, Maggie brought up her ex Liam (Marcus Rosner), a summer fling who seemed like a distant memory.
