Dr. Joss Reimer, recently appointed as Canada’s chief public health officer, is poised to tackle the dual challenges of health misinformation and the restoration of public trust in health institutions. In an interview conducted shortly after her appointment was announced, the Manitoba native expressed her concern over the rapid spread of false information in the health sector and the significant erosion of trust experienced during the COVID-19 pandemic.
The Urgency of Combatting Misinformation
Reimer highlighted the pressing need for a proactive stance from the federal government in addressing the pervasive issue 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 remarked. This sentiment underscores the necessity of consistent and accurate communication from health authorities to combat the surge of misleading narratives.
The pandemic era saw a tumultuous shift in public perception of health institutions. Reimer noted, “Trust in institutions has been significantly eroded.” She reflected on the hardships many Canadians faced, including job losses and separation from loved ones, which contributed to an environment of scepticism towards public health decisions. “We have a lot of trust-building that we’re going to need to do that’s going to take years,” she added, emphasising the long road ahead.
A Familiar Face in Public Health
Reimer steps into her new role following the retirement of Dr. Theresa Tam, who became a prominent figure during the pandemic as she provided near-daily updates on evolving health guidance. Reimer herself has been a visible public health figure, having served as chief medical officer for the Winnipeg health authority and leading Manitoba’s COVID-19 vaccine implementation task force.

Health Minister Marjorie Michel acknowledged the importance of Reimer’s appointment, stating that she joins the Public Health Agency at a crucial juncture. Canada is currently confronting a resurgence of vaccine-preventable diseases, including measles, alongside ongoing threats from avian influenza (H5N1), HIV, and tuberculosis, all compounded by the detrimental effects of misinformation.
Addressing Vaccine Hesitancy
Drawing from her personal experience, Reimer spoke candidly about the challenges surrounding vaccine hesitancy, especially in her hometown, which is currently experiencing a measles outbreak. “We need to forge partnerships from community leaders all the way up to the federal government,” she asserted. The measles outbreak has persisted long enough for Canada to lose its measles elimination status, a concerning development echoed by public health experts across the nation.
Reimer explained that the highly infectious nature of measles, combined with the increasing prevalence of misinformation, makes the rise in cases somewhat predictable. “It’s not a shock that measles cases are on the rise,” she stated, calling for a collective effort to address the roots of vaccine hesitancy.
The Need for Independent Information Sources
In a broader context, Reimer acknowledged that misinformation is not confined to social media platforms. In a past statement, Minister Michel remarked on the declining reliability of American health institutions as credible sources of information for Canadians, a sentiment that has intensified since the Trump administration. Reimer stressed the importance of Canada establishing its own credible information-sharing channels while continuing to collaborate with American health professionals. “I know that there are still really amazing people in the American system doing wonderful work,” she said, indicating her commitment to cooperative efforts in the health sector.

Reimer’s academic background includes a master’s degree in public health, with research focused on sexually transmitted diseases and drug-related harms. This expertise positions her well to guide Canada’s public health strategy moving forward.
Support from Public Health Leaders
Nancy Hamzawi, president of the Public Health Agency of Canada, expressed her enthusiasm for working alongside Reimer, stating, “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.” Dr. Margot Burnell, current president of the Canadian Medical Association, praised Reimer’s calm leadership during the pandemic, noting her proactive efforts to combat misinformation and advocate for equitable access to healthcare.
Reimer’s term is set to commence on April 1, marking the beginning of what many hope will be a renewed chapter in Canada’s public health narrative.
Why it Matters
The appointment of Dr. Joss Reimer comes at a pivotal moment for Canada’s public health landscape. With misinformation proliferating and public trust waning, her leadership will be crucial in navigating these tumultuous waters. The challenges ahead underscore the need for a concerted effort to restore faith in health institutions while ensuring that Canadians receive accurate, reliable information to guide their health decisions. Reimer’s unique perspective and commitment to collaboration may well determine the trajectory of public health in Canada for years to come.
