Canadian actress and model Dayle Haddon died Friday from a suspected incident of carbon monoxide poisoning which took place at the home of her son-in-law, Marc Blucas, who starred in the TV series “Buffy the Vampire Slayer,” according to local authorities. She was 76.
Haddon was discovered in Blucas’ home in Bucks County, Pa. CBS referenced a police officer stating high levels of carbon monoxide were detected inside the property. A malfunction with the heating unit was also suspected. It has not yet been confirmed if Blucas was present at the time of death.
Born and raised in Montreal, Haddon spoke both English and French. She was initially pursuing a career as a ballet dancer before becoming a model for Revlon, Estee Lauder, Clairol and Max Factor. She was featured on the cover of Vogue several times over the course of her career. She also appeared on the cover of the 1973 Sports Illustrated Swimsuit Issue and was recognized in Harper’s Bazaar’s list of “Ten Most Beautiful Women” twice.
Haddon transitioned to acting in the early 1970s. Her on-screen credits include “The World’s Greatest Athlete,” “Cheaters,” “Madame Claude,” “North Dallas Forty,” “Desert Chase,” “Cyborg” and “Bullets Over Broadway.”
She was later the face of L’Oreal’s anti-aging products as well as the author of the book “Ageless Beauty: A Woman’s Guide to Lifelong Beauty and Well-Being.”
Haddon was also an ambassador for the UN children’s relief fund UNICEF as well as the founder of WomenOne, a New York-based organization that helps expand educational opportunities for women.
