The Royal Christmas Crush was filmed primarily in Toronto, Canada. The production team scouted various locations around the city, including Casa Loma, the Distillery District, and the Don Valley Brickworks. The Christmas scenes were shot at Casa Loma, a historic castle that was transformed into a festive holiday wonderland. The production also used several other locations in the Toronto area, such as the Distillery District and the Don Valley Brickworks, to create a magical atmosphere for the Christmas season.
