Heartland is a Canadian family drama based on Lauren Brooke's book series, which debuted on CBC in 2007 and follows the lives of the Fleming family on their horse and cattle ranch in Alberta. The show centers on sisters Amy (Amber Marshall) and Lou (Michelle Morgan), who navigate ranch life alongside their grandfather Jack, estranged father Tim, and ranch hand Ty Borden, dealing with everything from natural horsemanship to deep family trauma. A major milestone came on October 19, 2014, when its 125th episode made it the longest-running one-hour scripted drama in Canadian television history, surpassing Street Legal. The series shows no signs of stopping, having been renewed through a 20th season (confirmed in May 2026), with filming for the 19th season beginning in May 2025. In the United States, it enjoys massive popularity through syndication, the Hallmark Channel (starting January 2025), and streaming services like Netflix and Hulu, while the plot remains gripping with major twists like the tragic death of Amy's husband Ty in season 14.
