The Hallmark show's season five finale marked the actor's last episode.

Goodbye, Jack Thornton.

Following Sunday's When Calls the Heart season five finale, Daniel Lissing took to Instagram to say farewell and thank all his Hearties for their unconditional support as his time on the show comes to an end.

"After the interviews yesterday regarding #whencallstheheart, I had a phone call about work overlooking LA," the 36-year-old actor wrote on Tuesday alongside picture of himself taking a mysterious call while overlooking the City of Angels. "I have no idea what the future holds for my career… But I’m excited to see what happens and I feel very lucky to have the support of the #hearties and @hallmarkchannel moving forward. #thankyouforeverything."

In Sunday's surprising finale, the series-long love story between school teacher Elizabeth Thatcher (Erin Krakow) and Canadian Mountie Jack Thornton (Lissing) came to a painful end when Jack died offscreen, leaving Elizabeth a bereaved widow -- although the surprise pregnancy cliffhanger at the end of the episode left fans with a ray of hope.

During a Facebook Live, Lissing explained his departure from the show.

"Circumstances arose for me where I needed to leave When Calls the Heart for reasons that are very personal to me," Lissing said without elaborating. "I went to Hallmark and they were nothing but supportive of me. I went to the girls and they were nothing but supportive of me."

He said that his relationship with his co-stars, the network and his fan base is still "a very positive one" and he's "very excited to see what the future brings."
