Dr. Joss Reimer, appointed as Canada’s chief public health officer, has prioritised the battle against health misinformation and aims to rebuild public trust in health institutions. In a recent interview, Reimer emphasised the urgent need for government action to combat the rapid spread of false health information, particularly in the wake of the COVID-19 pandemic, which has significantly eroded public confidence in health advisories.
A Shift in Public Health Leadership
Dr. Reimer’s appointment comes at a pivotal moment for Canada’s public health landscape. Taking over from Dr. Theresa Tam, who retired after eight years in the role, Reimer brings extensive experience from her tenure as Manitoba’s chief medical officer and her leadership of the province’s COVID-19 vaccine implementation task force. She noted that the pandemic brought health officials into the public eye, highlighting the importance of transparent communication and trust.
“The challenge of health misinformation is that it evolves rapidly. Crafting a lie takes little time,” Reimer stated, acknowledging the obstacles faced during the pandemic. She reflected on the emotional turmoil experienced by Canadians, pointing out that decisions made during such crises often came with significant hardships, leading to a decline in trust that will require years to mend.
Addressing Vaccine Hesitancy
Reimer’s perspective on health issues is deeply personal; she hails from a community affected by measles outbreaks and vaccine hesitancy. She underscored the necessity of forging partnerships that connect local community leaders with federal authorities to address public concerns. “We need a collaborative effort,” she explained.

The ongoing measles outbreak has led Canada to lose its measles elimination status for the first time since 1998, an alarming development echoed by public health experts. Reimer attributed this rise in cases to the disease’s highly contagious nature, compounded by increasing vaccine hesitancy and the proliferation of misleading information.
The Role of Misinformation
Health officials have recognised that misinformation extends beyond social media platforms. In a previous statement, Health Minister Marjorie Michel highlighted that the integrity of American health institutions has declined, which affects Canadians seeking reliable health information. The consequences of this shift were described as a “slap in the face” to the longstanding collaborative relationship between Canada and the U.S.
Reimer acknowledged the need for Canada to fortify its own health information systems, ensuring that trustworthy, evidence-based communication is at the forefront. “While there are still remarkable individuals in the American health system, Canada must ensure that we are independently sharing accurate information,” she asserted.
Commitment to Inclusive Health Policies
Dr. Reimer holds a master’s degree in public health and has a background in researching sexually transmitted diseases and drug-related harm. Her leadership is expected to steer Canada through its current health challenges, including the resurgence of vaccine-preventable diseases and the complexities posed by the ongoing opioid crisis.

Nancy Hamzawi, president of the Public Health Agency of Canada, expressed confidence in Reimer’s ability to lead with a science-driven approach. “In these critical times, her vision and dedication will be vital for advancing the health and well-being of Canadians,” she stated.
Reimer’s previous role as president of the Canadian Medical Association included a historic apology to Indigenous Peoples for the medical community’s past injustices, demonstrating her commitment to ethical leadership in health.
Why it Matters
Dr. Joss Reimer’s appointment as chief public health officer comes at a crucial time for Canada’s health system, grappling with the dual challenges of misinformation and declining public trust. Her proactive stance on fostering collaboration and addressing vaccine hesitancy is essential not only for restoring public confidence but also for safeguarding the health of future generations. As the nation faces a resurgence of preventable diseases, Reimer’s leadership could be pivotal in shaping a more resilient and informed society, underpinning the importance of accurate health communication in an increasingly complex information landscape.
