Dr. Joss Reimer has been appointed as Canada’s new chief public health officer, taking the helm at a pivotal moment for public health in the country. In a recent interview, she underscored the urgent need to address health misinformation and rebuild confidence in health institutions, particularly in the wake of the COVID-19 pandemic. This three-year appointment, announced on Friday, marks a critical step in Canada’s public health strategy as the nation grapples with a resurgence of vaccine-preventable diseases and the ongoing fallout of the pandemic.
Addressing Health Misinformation
Dr. Reimer, a Manitoba native, highlighted the rapid evolution of health misinformation as a significant challenge for public health officials. “One of the biggest challenges with health misinformation is the speed at which it changes,” she stated. This situation has been exacerbated by the emotional toll of the pandemic, which saw many Canadians facing job losses and separation from loved ones. “We have a lot of trust-building that we’re going to need to do that’s going to take years,” she added, acknowledging the erosion of faith in health institutions during this turbulent period.
The pandemic propelled public health leaders into the public eye, with Dr. Theresa Tam, Reimer’s predecessor, becoming a household name as she provided regular updates on the evolving health landscape. After an impactful eight-year tenure, Tam retired in June, leaving Reimer to step into this critical role.
A Unique Perspective on Public Health Challenges
Dr. Reimer’s experience as the chief medical officer for the Winnipeg health authority and her role in Manitoba’s COVID-19 vaccine task force have equipped her with valuable insights into the current health crisis. Health Minister Marjorie Michel emphasised the timeliness of Reimer’s appointment, noting that Canada is confronted with a resurgence of vaccine-preventable diseases such as measles, alongside threats from avian influenza A (H5N1), HIV, and tuberculosis.

Reimer has a personal connection to the ongoing measles outbreak, having grown up in a small town where vaccine hesitancy is prevalent. “We need to have partnerships from on the ground, from community leaders all the way up to the federal government,” she stressed. The loss of Canada’s measles elimination status, which had been in place since 1998, is a stark reminder of the challenges posed by misinformation and vaccine hesitancy.
The Need for Trustworthy Information
As misinformation proliferates beyond social media, Reimer acknowledges that Canada must assert its independence in public health messaging. Reflecting on the influence of American health institutions, she expressed concern over the reliability of information sources due to changes in leadership and policy. “I know that there are still really amazing people in the American system doing wonderful work, and so I think that there’s a lot of ways that we can continue to work together,” she affirmed.
With a master’s degree in public health and extensive research experience, including issues related to sexually transmitted diseases and drug-related harms, Reimer is well-equipped to lead Canada through these turbulent times. Nancy Hamzawi, president of the Public Health Agency of Canada, expressed confidence in Reimer’s leadership, emphasising the importance of science-driven decision-making in advancing public health.
A Commitment to Inclusivity and Healing
Reimer’s leadership is also marked by her commitment to addressing the historical harms inflicted on Indigenous Peoples by the medical profession. As a past president of the Canadian Medical Association, she has taken significant steps to advocate for better access to care and the fight against health misinformation. Dr. Margot Burnell, the current president of the CMA, commended Reimer for her calm and measured approach during the pandemic, noting her dedication to improving health outcomes for all Canadians.

Dr. Reimer is set to officially begin her term on April 1, and there is a palpable sense of hope that her leadership will steer Canada toward a more trustworthy and resilient public health system.
Why it Matters
Dr. Joss Reimer’s appointment comes at a crucial juncture for Canada’s public health landscape. As misinformation spreads and public confidence wanes, her focus on combating false information and rebuilding trust is essential for safeguarding the health of Canadians. In a world where health decisions must be informed by credible data and trust in institutions, Reimer’s leadership could herald a new era of transparency and collaboration in public health, ultimately leading to improved health outcomes for all.
