The bus that Grace boards actually does belong to Tisdale Bus Lines (as it says on the bus), headquartered in Porcupine, Ontario.
Kellie Martin was initially cast as Grace when the film was first announced in March 2018. At some point in the five and a half months leading up to filming, she was replaced with Eloise Mumford for unknown reasons.
Aired as the second of sixteen original films in Hallmark Movies & Mysteries' 2018 "Miracles of Christmas" lineup (replacing the "Most Wonderful Movies of Christmas" lineups of the previous years).
