Dr. Joss Reimer, recently appointed as Canada’s chief public health officer, has outlined her commitment to addressing the pervasive issue of health misinformation while working to rebuild public confidence in health institutions. In an interview conducted on the day her three-year tenure was announced, the Manitoba native acknowledged the challenges posed by the rapid spread of false information and the trust deficit that has emerged since the COVID-19 pandemic.
Combating the Spread of Misinformation
Reimer emphasised the pressing need for the federal government to adopt a proactive stance against health misinformation. “One of the biggest challenges with health misinformation is the speed at which it changes, because it doesn’t take a lot of time to come up with a lie,” she remarked. Her insights reveal a clear recognition of the detrimental impact that misinformation can have on public understanding and health behaviours.
Reimer is acutely aware of the erosion of trust in public institutions, particularly health-related ones, that many Canadians experienced during the pandemic. “People were losing jobs and income, and being separated from loved ones. And whether or not those were right decisions, it was hard,” she stated, indicating that restoring this trust will be a lengthy process requiring significant effort.
A Transition of Leadership
Dr. Theresa Tam, Reimer’s predecessor, became a prominent figure during the pandemic, delivering frequent updates to the public. After serving for eight years, Tam retired in June, leaving behind a challenging legacy. Reimer, who served as the chief medical officer for the Winnipeg health authority and led Manitoba’s COVID-19 vaccine implementation task force, steps into this pivotal role at a time of critical health challenges.

Health Minister Marjorie Michel highlighted the importance of Reimer’s appointment, noting that Canada is currently grappling with a resurgence of vaccine-preventable diseases, including measles, and other pressing health threats such as avian influenza, HIV, and tuberculosis. The ongoing opioid crisis and the pervasive influence of misinformation further complicate the landscape.
The Urgency of Addressing Vaccine Hesitancy
Reimer’s perspective on the recent measles outbreak is particularly personal; she hails from a small town affected by vaccine hesitancy. “We need to have partnerships from on the ground, from community leaders all the way up to the federal government,” she stated, emphasising the importance of a collaborative approach to public health. Alarmingly, the outbreak has led Canada to lose its measles elimination status, a designation held since 1998, raising concerns among public health officials nationwide.
The contagious nature of measles, paired with increasing misinformation and vaccine hesitancy, has created a perfect storm for health crises. Reimer’s awareness of these dynamics reflects a broader understanding of the complexities involved in public health communication and the urgent need for a coordinated response.
Rebuilding Trust in Health Institutions
Reimer’s commitment to improving public trust is echoed by Nancy Hamzawi, the president of the Public Health Agency of Canada, who expressed confidence in Reimer’s vision and dedication during this critical period. Similarly, Dr. Margot Burnell, current president of the Canadian Medical Association, praised Reimer’s calm and measured leadership during the pandemic. Her prior efforts to combat misinformation and advocate for equitable access to healthcare demonstrate her readiness to tackle the challenges ahead.

As Reimer prepares to officially begin her term on April 1, she brings a wealth of experience, including a master’s degree in public health and extensive research on health issues including sexually transmitted diseases and drug-related harms.
Why it Matters
Reimer’s appointment comes at a crucial juncture in Canadian public health. The dual challenges of misinformation and declining trust in health institutions threaten the efficacy of health policies and the well-being of communities. By prioritising transparency and collaboration, Reimer has the potential to not only stem the tide of misinformation but also to foster a culture of trust that is vital for the future of Canada’s public health landscape. As the country faces a resurgence of preventable diseases and ongoing health crises, her leadership will be instrumental in steering Canada towards a healthier future.
