Model Dayle Haddon found dead from suspected carbon monoxide poisoning at Hallmark actor Marc Blucas’s Pennsylvania home

Dayle Haddon, the Canadian supermodel who rose to fame for her work representing various cosmetic and magazine companies, died Friday from suspected carbon monoxide poisoning. She was 76.

Haddon was found dead in a second-floor bedroom of a detached in-law suite at a home on the 6900 block of Phillips Mill Road in Solebury Township, Pa.

The million-dollar home is owned by Haddon’s journalist daughter Ryan Haddon and son-in-law Hallmark actor Marc Blucas, according to 6ABC News.

“The bright light that is Dayle has dimmed in this Earthly realm,” Ryan posted in a tribute on Friday. “Shining somewhere as radiantly as ever where it’s most needed, I have no doubt.

“She was a woman in her power, yet soft and attentive to all. Deeply creative and curious, gifted with beauty inside and out. Always kind and thoughtful.”

First responders were called to the property just after 6:30 a.m. Friday after receiving reports of a 76-year-old man lying unconscious on the first floor of the suite, the Solebury Township Police Department said.

The unidentified man was removed from the building and brought to a nearby hospital before rescuers learned that the woman, later identified as Haddon, was still inside.

The model was discovered inside and pronounced dead at the scene.

Blucas and Ryan Haddon purchased the “old farmhouse” in 2012 for $1 million, and completely restored the property that dated back to 1711, Blucas told Wide Open Country.

The New Hope Eagle Volunteer Fire Company detected a “high level of carbon monoxide” on the property.

Two medics were hospitalized due to exposure to the poisonous gas and a police officer was treated at the scene for injuries with all three in stable condition, the police department said.

No one in the main home was injured, with police believing a heating unit malfunctioned causing the high levels of carbon monoxide, CBS reported.

During her modeling career, Haddon signed four contracts with major cosmetic companies Revlon, Max Factor, Estée Lauder and L’Oréal, according to her website.

She’s been featured on the covers of Vogue, Elle, and Cosmopolitan.

The longtime spokeswoman for L’Oréal is credited for representing the brand throughout Europe, China and North America during her over 15-year campaign.

She appeared on the cover of Sports Illustrated in 1973.

“She held so many up, saw their greatness sometimes hidden to them, and always built bridges with her own connections to help them ascend,” Ryan said. She was everyone’s greatest champion. An inspiration to many.

“I always trust the timing of things. There are no accidents and certainly how we enter and exit this world is mystical and unknowable. She was a high-hearted spiritual being that put value on her soul’s evolution, so I know her journey here in this dimension must have been complete.”

Haddon was a UNICEF Ambassador and founded the New York-based WomenOne charity focused on delivering access to quality education to every girl in the world.

She has authored two books, “Ageless Beauty” and “The 5 Principles of Ageless Living.”

Haddon’s final Instagram post on Dec. 19, promoted her appearance on the “Shift Happens” podcast with Claudia Mahler where they discussed “How to Gracefully Beat Ageism in Fashion.”
