Eileen de Villa

The provincial government began loosening restrictions in March 2021, with de Villa expressing concerns regarding the growing presence of COVID-19 variants in the city and urging caution. De Villa urged the province to enhance its measures, and amidst a rapid increase in cases and growing ICU occupancy in April 2021, the provincial government issued a new stay-at-home order on April 8. De Villa warned that the rate of daily cases may outpace the ability to rollout vaccines, and that the city remained at risk, even with new restrictions. She issued a section 22 order on April 6, closing Toronto schools from April 7 to April 19, a day after Dr. Lawrence Loh of the Region of Peel issued a similar order for its schools. The Ontario government shortly ordered all schools closed province-wide, following a record number of cases, just a day after education minister Stephen Lecce insisted schools remained safe. The province took further action on April 16, announcing new restrictions and enhanced enforcement measures. On April 20, in conjunction with Peel Region's public health unit, Toronto Public Health announced that de Villa would issue section 22 orders to close workplaces with active COVID-19 outbreaks. De Villa and Loh also called on the Ford government to restore paid sick leave, which would reduce income disruption for workers isolating due to COVID-19.

On December 7, 2021, de Villa announced that she would be taking a leave of absence until December 20 in order to have surgery to address the a mass of pre-cancerous cells, initially discovered following a mammogram she had in the summer. Deputy Medical Officer of Health Dr. Na-Koshie Lamptey will serve as Medical Officer of Health during her absence. De Villa took the opportunity to encourage others to ensure they keep up with routine health screenings to catch problems early.

As Medical Officer of Health, de Villa has been leading the public health response to the COVID-19 pandemic in Toronto since the city saw its first case of COVID-19 on January 25, 2020.

In April 2020, de Villa initially used her authority under section 22 of the Health Protection and Promotion Act to order all individuals with COVID-19—as well as those who have been in contact with confirmed cases—to remain home for 14 days. Throughout the COVID-19 response, she has advised Mayor John Tory on measures the municipal government could take, such as declaring a state of emergency—which allows the mayor to assume the powers of Toronto City Council and expedite legislation—introducing a physical distancing bylaw in parks, and advised City Council to pass a bylaw mandating face masks.

While COVID-19 case numbers remained stable throughout the summer, in September 2020 de Villa warned of a resurgence in cases based on data from other jurisdictions, urging provincial and municipal leaders to develop new measures for the coming months. On September 29, Premier Doug Ford conceded that the province was experiencing a second wave and began to study implementing a new restrictions framework.

She has worked to combat the opioid epidemic in Toronto, advocating for a series of policies to expand public health services. Her recommended policies include the creation of a safer drug supply to reduce the need to buy drugs off the street, better support for under-served populations, and decriminalizing drugs. In 2019, she pushed back against budget cuts proposed by the Progressive Conservative government of Premier Doug Ford, which would limit the city's resources for fighting the opioid crisis and other public health programs. She has also criticized the province for defunding supervised injection sites, which have reversed a significant number of overdoses since opening.

Eileen Patricia de Villa is an American-Canadian physician and public servant who has served as Medical Officer of Health for the City of Toronto since 2017, leading the Toronto Public Health unit.

On March 27, 2017, de Villa began her term as the medical officer of health at Toronto Public Health following the retirement of David McKeown. She was appointed for her evidence-based approach to public health.

De Villa has worked as a public health physician since 2004, for the Region of Peel from 2004 to 2017 (including as medical officer of health) and City of Toronto since 2017, serving as the medical officer of health.

In 2004, de Villa began her almost thirteen year tenure at the Regional Municipality of Peel Office of Health, where she ultimately became the medical officer of health, serving from October 2015 to March 2017. There, she worked on a number of public health issues, including vaccination and prevention of communicable diseases, such as sexually transmitted infections and tuberculosis. She also oversaw the region's air quality and food and water safety. In 2016, de Villa offered a job as Associate Medical Officer of Health to Dr. Lawrence Loh, who later took over her position at Peel Region.

De Villa then decided to go to medical school, receiving her doctor of medicine (MD) degree from the University of Toronto in 1998. She completed her residency in family medicine in 2000 and in community medicine (public health) in 2004. She later received a master of business administration (MBA) degree from the Schulich School of Business at York University.

Through that experience, she became interested in international health.

She was born in Boston, Massachusetts, and briefly lived in the Philippines between 1972 and 1975 before her family fled to Canada.
