Dr. Joss Reimer, newly appointed chief public health officer of Canada, is determined to address the spread of health misinformation while rebuilding public confidence in health institutions. Announced in an interview on Friday, Reimer, a Manitoba native, emphasised the urgent need for the federal government to adopt a proactive stance against false information that has proliferated, particularly throughout the COVID-19 pandemic.
Emphasising the Challenge of Misinformation
“One of the biggest challenges with health misinformation is the speed at which it changes,” Reimer stated. “It doesn’t take much time to create a lie.” Her comments reflect a critical issue that has plagued public health communications, especially in light of the pandemic, which saw a significant erosion of trust in institutions.
Reimer acknowledged that the pandemic brought considerable hardships for many Canadians, including job losses and separation from loved ones. “Whether those decisions were right or wrong, it was hard,” she pointed out. “We’re going to need years to rebuild that trust.”
A Critical Moment for Public Health
Reimer steps into her role at a pivotal moment as Canada grapples with rising cases of vaccine-preventable diseases, such as measles, as well as ongoing threats from avian influenza A (H5N1), HIV, and tuberculosis. Health Minister Marjorie Michel highlighted the urgency of Reimer’s appointment, noting the additional challenges posed by the illegal drug crisis and the damaging effects of misinformation on public health.

Reimer has a personal connection to the current measles outbreak, having grown up in a small town affected by vaccine hesitancy. “We need partnerships from community leaders to the federal government to effectively address this,” she said, underscoring the importance of grassroots involvement in public health initiatives.
The measles outbreak has been severe enough that Canada has lost its measles elimination status, a troubling development echoed by public health experts nationwide. The highly contagious nature of measles, combined with rising vaccine hesitancy and misinformation, has created fertile ground for this resurgence.
The Need for Reliable Information
Misinformation is not confined to social media; it has infiltrated various channels of communication. Reimer expressed concern about the reliability of American health institutions, particularly following the Trump administration’s cuts to research funding and the promotion of falsehoods regarding vaccines. “Canada needs to stand on its own,” she asserted, while also recognising the importance of collaborative efforts with American health professionals who continue to do commendable work.
Reimer holds a master’s degree in public health and has a strong background in research related to sexually transmitted diseases and drug-related harms. Nancy Hamzawi, president of the Public Health Agency of Canada, expressed confidence in Reimer’s ability to lead during this critical time, stating, “Strong, science-driven leadership has never been more important.”
A Legacy of Advocacy
As a former president of the Canadian Medical Association, Reimer has been instrumental in advocating for improved access to healthcare and combating false health narratives. Dr. Margot Burnell, the current president of the CMA, praised Reimer for her calm and measured leadership during the pandemic, highlighting her commitment to fighting misinformation and advocating for equitable healthcare access across Canada.

Reimer is set to officially commence her role on April 1, and her leadership will be closely monitored as she embarks on this challenging yet essential mission.
Why it Matters
Reimer’s appointment represents more than just a new leader for Canada’s public health sector; it signals a renewed commitment to addressing health misinformation and restoring public trust. As the nation faces a multitude of health challenges exacerbated by misinformation, Reimer’s role will be vital in navigating this complex landscape and ensuring that Canadians have access to accurate, reliable health information. Her success in this role could significantly influence public health outcomes and the overall wellbeing of Canadians in the years to come.
