When Daniel Lissing announced he was leaving Hallmark’s When Calls the Heart after Season 5, Hearties were stunned. His character, Mountie Jack Thornton, had become one of the show’s most beloved figures, making his departure one of the most emotional moments in the series.
Years later, fans are still asking the same question: Why did Daniel Lissing leave When Calls the Heart?
Daniel Lissing Chose Not to Renew His Contract
Rather than being written out unexpectedly, Lissing made the decision to leave when his contract expired after five seasons. He has explained that personal circumstances led him to move on and said Hallmark and his co-stars were supportive of his choice.
Although he has never shared every detail behind the decision, he has consistently described it as a personal and professional choice.
Jack Thornton Was Killed Off

Because Lissing chose to leave the series, the writers decided to give Jack Thornton a permanent ending.
In one of the most heartbreaking episodes in When Calls the Heart history, Elizabeth Thornton learns that Jack was killed while leading Mounties on assignment, leaving her to raise their unborn son alone.
Series co-creator Brian Bird later explained that killing off Jack became the only realistic way to explain the character’s departure after Lissing decided to move on.
Daniel Lissing Has No Regrets
Despite how difficult the exit was for fans, Lissing has repeatedly said he doesn’t regret leaving the series.
In interviews, he explained that stepping away from the show allowed him to pursue other opportunities and ultimately led him to meeting his future wife, Nadia, whom he married in 2020. Looking back, Lissing has said everything happened the way it was meant to.
Could Daniel Lissing Return?
Since Jack Thornton died in the original series, a traditional return isn’t possible.
However, Lissing has reprised the character in special appearances, including the Hallmark spinoff When Hope Calls, proving that flashbacks, dream sequences, or special stories remain possibilities.
Hearties Still Miss Jack Thornton
Even more than a decade after When Calls the Heart premiered, Jack Thornton remains one of Hallmark’s most iconic characters.
While the series has continued with new storylines and romances, many longtime viewers still consider Jack and Elizabeth’s love story the emotional heart of the show.
