Much of the series is filmed on location in and around High River , Alberta , with additional filming in studio and on location in nearby Calgary . A June 2013 flood in High River swamped the standing set for Maggie 's Diner . The main '' Heartland '' sets escaped damage , and seventh season scripts were rewritten to move shooting locations for the fictional town of Hudson to Inglewood , a historic neighborhood in downtown Calgary . A month after the flood , the show 's Calgary studios offered behind-the-scenes tours to paying fans for a one-day " Heartlanders for High River " fundraiser , providing $ 80,000 to help the town recover
