Dr. Joss Reimer, appointed as Canada’s new Chief Public Health Officer, has set her sights on addressing the rampant health misinformation that has proliferated in recent years while working to rebuild the public’s trust in health institutions. Her three-year tenure, which was announced on Friday, will commence on April 1, 2024. In a recent interview, Dr. Reimer stressed the urgent need for the federal government to adopt a proactive stance against false health narratives that have emerged, particularly during and after the COVID-19 pandemic.
The Challenge of Health Misinformation
Dr. Reimer, who hails from Manitoba, highlighted the rapidly evolving nature of 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 explained. This relentless tide of falsehoods has created significant obstacles for public health officials attempting to convey accurate information.
The COVID-19 pandemic has undeniably strained public trust in health systems, with many Canadians experiencing substantial upheaval in their lives. “People were losing jobs and income, and they were separated from loved ones,” Dr. Reimer reflected. “Whether or not those were right decisions, it was hard. We have a lot of trust-building to do, and that’s going to take years.”
A Legacy of Leadership
Dr. Reimer steps into her new role following the retirement of Dr. Theresa Tam, who became a prominent figure in Canadian households as she provided regular updates throughout the pandemic. During her tenure, Dr. Tam earned the trust of many Canadians, but the challenges ahead remain significant.

Dr. Reimer previously served as the Chief Medical Officer for the Winnipeg health authority and played a vital role in Manitoba’s COVID-19 vaccine implementation task force. Her experience during the pandemic positions her uniquely to tackle the pressing health issues currently facing Canada.
Addressing Vaccine Hesitancy and Emerging Threats
In her new capacity, Dr. Reimer will focus on urgent public health challenges, including a marked resurgence of vaccine-preventable diseases like measles, as well as threats posed by avian influenza A (H5N1), HIV, and tuberculosis. Health Minister Marjorie Michel acknowledged the critical nature of Dr. Reimer’s appointment, stating, “Canada is facing a resurgence of vaccine-preventable diseases and the harmful impacts of false health information.”
Dr. Reimer shared her personal connection to the ongoing measles outbreak, noting that her hometown is affected by the rising vaccine hesitancy. “We need partnerships from on the ground, from community leaders all the way up to the federal government,” she stressed. The country has lost its measles elimination status, a troubling development that public health experts regard as alarming.
The Importance of Accurate Health Information
Beyond social media, misinformation has infiltrated traditional health communication channels. Dr. Reimer pointed out that the relationship between Canadian and American health institutions has been strained, particularly following the policies of the previous U.S. administration, which undermined scientific integrity. “Canada needs to stand on its own and ensure it’s sharing trustworthy information,” she affirmed, while also recognising the valuable work still being done by many in the American health system.

Dr. Reimer holds a master’s degree in public health and has a strong background in researching sexually transmitted diseases and drug-related harms. Her prior leadership roles, including her tenure as president of the Canadian Medical Association, allowed her to advocate for increased access to healthcare and address the challenges posed by misinformation effectively.
Why it Matters
Dr. Joss Reimer’s appointment comes at a pivotal moment for Canada’s public health landscape. As misinformation continues to pose a significant threat to community health, her leadership will be crucial in restoring faith in healthcare institutions and fostering collaborative efforts to ensure that accurate and reliable health information reaches all Canadians. The challenges are formidable, but with a renewed focus on trust-building and community engagement, there is hope for a healthier future.
