Marjorie Amy Ferris, 70, was last seen at her Burlington, Ontario apartment on March 5, 1993, the day she was due to meet friends in London to begin a trip to Florida. Family found her home secure with no signs of struggle: her purse was beside her bed, her wallet with $45 U.S. on the dining table, chequebook present, car keys inside and her vehicle parked in the underground garage. The only items noted missing were her winter boots. She was described as 5 feet 4 inches, medium build, with dark wavy collar-length hair, blue eyes and glasses; she was believed to have been wearing grey slacks, a sweatshirt-style top and a dark green ski jacket with red and orange accents.

Halton Regional Police mounted air and ground searches, canvassed the neighbourhood and distributed flyers; family placed a newspaper plea. A severe winter storm on the night of her disappearance and Marjorie’s habit of walking along the waterfront at Spencer Smith Park have led investigators to consider that she might have fallen into Lake Ontario, but no concrete evidence has ever been found. The circumstances remain unexplained.
