Dr. Joss Reimer, recently appointed as Canada’s chief public health officer, has identified addressing health misinformation and rebuilding trust in public health as her primary objectives. In her first interview following the announcement of her three-year tenure, Reimer emphasised the urgent need for the federal government to adopt proactive measures to counteract the rapid spread of false health information, a growing concern in the wake of the COVID-19 pandemic.
Acknowledging the Trust Deficit
Reimer, a native of Manitoba, recognised that the pandemic significantly damaged public trust in health institutions. “The challenges posed by job losses, income instability, and separation from loved ones created a context where trust was severely tested,” she noted. The ramifications of these experiences, she believes, will necessitate years of dedicated effort to rebuild the confidence of Canadians in public health authorities.
As Reimer steps into her new role, she follows in the footsteps of Dr. Theresa Tam, who became a prominent figure during the pandemic with her frequent updates and guidance. Tam retired in June after an impactful eight-year tenure, leaving behind a complex landscape for her successor to navigate.
Experience During the Pandemic
Having served as Manitoba’s chief medical officer and leading the province’s COVID-19 vaccine implementation task force, Reimer brings a wealth of experience to her new position. In her view, the current resurgence of vaccine-preventable diseases, alongside the threat of avian influenza A (H5N1), HIV, and tuberculosis, poses a significant challenge. Health Minister Marjorie Michel highlighted the pressing need for Reimer’s expertise, as misinformation continues to undermine public health efforts.

Reimer expressed her personal connection to the urgent issue of vaccine hesitancy, particularly with the ongoing measles outbreak affecting her hometown. “Partnerships are essential, from grassroots community leaders to federal stakeholders,” she stated, emphasising the importance of a unified response to enhance vaccine acceptance.
The Measles Crisis and Its Implications
Canada’s recent loss of its measles elimination status, a position it had maintained since 1998, has alarmed public health experts. The resurgence of measles cases is not unexpected, given the disease’s highly contagious nature and the increasing prevalence of misinformation. Reimer remarked, “We are seeing the consequences of vaccine hesitancy compounded by a pervasive spread of false information.”
This public health issue extends beyond social media. In a previous statement, Michel indicated that American health organisations, once reliable sources of information, have been compromised, limiting their credibility in the eyes of Canadians. “We must ensure that Canada stands independently, providing accurate and trustworthy health information,” Reimer asserted. She remains optimistic about potential collaborations with American health professionals, recognising their valuable contributions despite the current challenges.
A Vision for the Future
Dr. Reimer’s academic background, which includes a master’s degree in public health, and her prior work addressing sexually transmitted diseases and drug-related harms, position her well to lead Canada’s public health strategy. Nancy Hamzawi, president of the Public Health Agency of Canada, expressed confidence in Reimer’s ability to drive science-based initiatives that will enhance the health and well-being of Canadians.

Reimer’s leadership style has already garnered praise. Dr. Margot Burnell, the current president of the Canadian Medical Association, praised her as a source of calm and measured guidance throughout the pandemic. Under her previous leadership, Reimer actively fought against false health information and advocated for healthcare access improvements for all Canadians.
As she prepares to begin her term on April 1, Reimer is poised to tackle the multifaceted challenges facing Canada’s public health landscape.
Why it Matters
Dr. Joss Reimer’s appointment comes at a critical juncture for Canada as it grapples with the repercussions of a global health crisis and the persistent threat of misinformation. Her commitment to rebuilding trust and effectively communicating accurate health information is essential for fostering a healthier society. As misinformation continues to spread, the importance of strong, knowledgeable leadership in public health cannot be overstated. Reimer’s vision and experience will be crucial in navigating these turbulent waters, ultimately aiming to restore the faith of Canadians in their health institutions and safeguard public health for future generations.
