The Lady in White – Montmorency Falls, Que. Hidden in the roar of Montmorency Falls are the cries of La Dame blanche (the Lady in White) calling out for her lost love. It was at the falls that Mathilde Robin’s fiancé, Louis Tessier, had courted her. Little did the betrothed couple know that Louis was soon to perish in battle during the Seven Years’ War. Overwhelmed with grief at the news of this death, Mathilde donned her wedding gown and tossed herself into the raging cataract.
