Ken Walker

Kenneth Francis Walker (28 February 1924 – 1 July 2025) was a Canadian medical writer, celebrity doctor, obstetrician, gynecologist and abortion practitioner. As an author and columnist, he published under the pen name W. Gifford-Jones, M.D. first settling in Montreal and then in Niagara Falls, Ontario.

Walker earned his undergraduate degree from the University of Toronto and graduated from Harvard Medical School in 1950.

He received his surgical training at the University of Rochester and McGill University as well as Harvard Medical School. Early in his career he was variously a family doctor, hotel doctor at the Manoir Richelieu Hotel at Murray Bay, Quebec, and ship’s surgeon. On his first Atlantic crossing he relieved the captain of his command due to illness.

The Postmedia chain, including the Toronto Sun ceased carrying the Gifford-Jones column at the end of 2019.

In his last years, the column was published online and in smaller newspapers such as the Westerly Sun, the Kingsville Times, the Penticton Herald, and the Prince Albert Daily Herald

Walker continued to contribute a weekly column until his death, claiming never to have missed a week in fifty years. From 2020 until his death in 2025, he co-authored the column with his daughter, Diana MacKay who used the pen name Diana Gifford-Jones. She continued as sole author of the weekly column after his death.

Campaigns and advocacy While practicing in Niagara Falls, Ontario, Walker was an advocate of women's right to choose abortion and was an abortion practitioner in the area after the procedure became legal in 1969, resulting in death threats from abortion opponents. His foundation donated $500,000 to the University of Toronto Medical School to establish the Gifford-Jones Professorship in Pain Control and Palliative Care.

Walker also advocated the right to assisted suicide and euthanasia and was a member of the physicians advisory council of Dying with Dignity Canada.

Medical views and criticisms Alternative medicine When he was 74, Walker suffered a serious heart attack and soon after had a triple bypass operation. He rejected the recommended statin therapy and recalling an interview he had with Linus Pauling advocating Vitamin C megadosage, began a regimen of 10 grams of Vitamin C and 5 grams of the amino acid lysine, which he claimed saved his life. Walker's advocacy of a combination of large dosages of Vitamin C and lysine to prevent or reverse coronary disease and his questioning of the use of statins has been criticized by medical professionals and also led to accusations that Walker's advocacy of this and other alternative treatments puts him in a conflict of interest as he sells vitamin supplements online, including a product that combines Vitamin C and lysine. Dr. Raphael Cheung, an endocrinologist at Windsor Regional Hospital, wrote in an op-ed response to Walker's advice that: “Dr. Gifford-Jones’ anecdotal experience belongs to medicine that was practiced half a century ago!” adding "Why does [the Windsor Star] keep printing articles written by a retired OB-GYN regarding vascular health? Not knowing any better, there are patients who are at high risk for heart disease and stroke in our community who have stopped taking their medications after reading Gifford-Jones articles." Cheung also stated that he was surprised when a patient with coronary heart disease told him that he had stopped his heart medications and "had started taking Dr. Gifford-Jones’s Medi-C Plus treatment purchased online.” Views on vaccination In 2018, the Toronto Sun pulled a Gifford-Jones column from its website following an outcry over its urging readers to consider "both sides of the vaccine debate". Sun editor Adrienne Batra said it was removed from the newspaper's website after medical professionals pointed out inaccuracies in the column. His public advocacy for understanding both the benefits and risks of vaccines dates back to 1974, when he published two articles about the swine flu epidemic taking place that year. In 2021, Gifford-Jones came down in favour of the COVID-19 vaccine, writing "I have never been against vaccination and proven science" and in regards towards COVID-19 vaccines "the risk is so, so minimal versus the risk of dying unvaccinated".

Views on apartheid South Africa In 1986, Walker participated in a "fact finding" tour of South Africa sponsored by the apartheid government. Upon his return he wrote an op-ed in the Globe and Mail titled "The good side of white South Africa" which opposed sanctions against or disinvestment from South Africa and also opposed the prospect of ending white minority rule in the country.

Later life and death After spending much of his life in Niagara Falls, Walker and his wife moved to Toronto's Harbourfront neighbourhood where they celebrated their 60th anniversary in 2016. The city of Niagara Falls, Ontario, declared the day Dr. W. Gifford-Jones Day and staged a special illumination of Niagara Falls in his honour.

At the age of 100, he published Healthy Retirement Residence Living: What Does Gifford-Jones Say? (2024) which he announced would be his "final book".

Walker died on 1 July 2025, at the age of 101. He was cremated at his own request. In 2018, he wrote: "My family knows I want a simple bench along the waterfront in Toronto where people can relax and enjoy the view. My ashes beneath can help the trees grow."
