Dr. Joss Reimer, Canada’s newly appointed chief public health officer, has outlined her vision to tackle health misinformation and restore public confidence in health institutions. Announced on Friday, her three-year tenure comes at a pivotal moment as the country grapples with the lingering effects of the COVID-19 pandemic and an uptick in vaccine-preventable diseases.
A Proactive Approach to Misinformation
In a recent interview, Dr. Reimer emphasised the urgent need for a proactive government strategy to counteract the rapid spread 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 noted. This challenge is compounded by the erosion of trust in health authorities during the pandemic, a sentiment she acknowledges has deeply affected public perception.
Dr. Reimer reflected on the tumultuous period of COVID-19, stating, “People were losing jobs and income, and many were separated from loved ones. Regardless of whether those decisions were right or wrong, they were difficult. We have a significant amount of trust-building to do, and it will take years.”
Learning from the Pandemic
Dr. Reimer’s predecessor, Dr. Theresa Tam, became a prominent figure during the pandemic, providing near-daily updates that kept Canadians informed about the evolving landscape of public health. Tam retired in June after eight years of service, leaving behind a legacy of resilience in the face of unprecedented health challenges.

Having served as the chief medical officer for the Winnipeg health authority and as the medical lead for Manitoba’s COVID-19 vaccine implementation task force, Dr. Reimer brings a wealth of experience to her new role. She understands firsthand the complexities of public health messaging and the importance of community engagement.
Addressing Vaccine Hesitancy and Outbreaks
In her new position, Dr. Reimer is particularly concerned about the resurgence of vaccine-preventable diseases, such as measles. “I come from a small town which is part of the measles outbreak, where we have seen a fair bit of vaccine hesitancy,” she stated, emphasising the importance of forging partnerships that reach from local community leaders to federal authorities.
Canada has lost its measles elimination status, a distinction it had maintained since 1998, which public health experts deem alarming. The rise in measles cases is not surprising, according to Dr. Reimer, considering the disease’s highly infectious nature and the increasing prevalence of misinformation surrounding vaccinations.
The Role of Trust and Collaboration
Health Minister Marjorie Michel highlighted the critical nature of Dr. Reimer’s appointment, citing the multitude of public health challenges currently facing Canada. “We are dealing with a resurgence of vaccine-preventable diseases and the ongoing impacts of the illegal drug crisis,” she remarked, underscoring the need for accurate health information.

Dr. Reimer advocates for an independent approach to health communication, ensuring that Canadians receive trustworthy information devoid of external misinformation. She acknowledges that while the American health system still harbours dedicated professionals, Canada must prioritise its own health narrative. “There are still amazing people in the American system doing wonderful work, and we can continue to collaborate, but we need to ensure that we’re sharing reliable information with Canadians,” she asserted.
A Commitment to Public Health
Dr. Reimer holds a master’s degree in public health and has previously conducted research on sexually transmitted diseases and drug-related harms. Her leadership will be crucial as she steps into a role that demands both scientific expertise and compassionate outreach.
Nancy Hamzawi, president of the Public Health Agency of Canada, expressed confidence in Dr. Reimer’s ability to advance public health initiatives. “At a time when strong, science-driven leadership has never been more important, I am confident that her vision and dedication will help advance the public health and well-being of Canadians,” she stated.
Dr. Reimer also has a history of advocating for improved access to healthcare, as demonstrated during her presidency at the Canadian Medical Association, where she issued a formal apology to Indigenous Peoples for historical harms caused by the medical profession.
Why it Matters
The appointment of Dr. Joss Reimer comes at a critical juncture for Canada’s public health landscape. As misinformation threatens to undermine the progress made in vaccination and public health efforts, her focus on rebuilding trust and fostering community partnerships is essential. The path ahead will require concerted efforts across all levels of government and society to ensure that accurate health information prevails, ultimately safeguarding the health of all Canadians.
