A doctor with ties to Saskatchewan and Ontario has had his medical licence suspended after being charged with dozens of sex crime-related offences in Toronto late last year.

David Edward-Ooi Poon garnered significant media attention during the COVID-19 pandemic after starting an organization working to re-unite families separated by travel restrictions.

According to the colleges of physicians in Saskatchewan and Ontario, responsible for regulating the profession in each province, Poon had training in family medicine and later earned a specialization in public health.

He was first charged by Toronto police in November 2025 for possessing and accessing child sexual abuse material.

Based on records from the colleges, at that time Poon was released on bail conditions limiting his access to the internet and was barred from attending to patients under 18-years-old or acting in a position of trust or authority over minors.

A month later, he was arrested a second time in Toronto and charged with an additional 40 offences alleged to have occurred between 2014 and 2024, including multiple counts of sexual assault, sexual assault with a weapon, administering drugs to “overcome resistance,” voyeurism and multiple counts of creating child sexual abuse and exploitation material.

He’s been in custody since — and had his medical licence suspended in both provinces.

His records show he worked out of the Population Health Unit in La Ronge and also practiced in Ontario.

Under his LinkedIn profile, Poon disclosed he was an employee of the University of Saskatchewan (U of S), working as an assistant professor of public health and as a safety and wellness representative for medical residents’ exam preparation.

A spokesperson for the U of S told CTV News Poon was not employed by the university and had no active appointments, but was under a temporary contract to Northern Medical Services until November 2025, “and has not provided services since then.”

“Dr. Poon has not provided service in the exam preparation role since July 2025, and such role is no longer in place. He does not hold the assistant professor role in the Division of Public Health and Preventive Medicine,” the spokesperson said.

He’s expected to make another appearance before the Ontario Court of Justice tomorrow.
