Dr. Joss Reimer has been appointed as Canada’s new chief public health officer, with a commitment to addressing health misinformation and restoring public confidence in health institutions. In her inaugural interview following the announcement of her three-year appointment, Reimer highlighted the urgent need for proactive strategies to counter the rapid spread of false health information, which has significantly undermined trust during the COVID-19 pandemic.
The Challenge of Misinformation
Reimer, a native of Manitoba, acknowledges the complex landscape of health information today. “One of the biggest challenges with health misinformation is the speed at which it changes,” she explained. “It doesn’t take much time to create a lie.” The COVID-19 pandemic has severely impacted public trust, with many Canadians feeling disconnected from health institutions due to the crisis’s multifaceted challenges.
She reflected on the difficulties faced during the pandemic, stating, “People were losing jobs and income, and being separated from loved ones. Whether those decisions were right or wrong, they were hard.” Rebuilding this trust will be a long-term endeavour, requiring sustained effort over several years.
A Legacy of Leadership
Dr. Reimer steps into the role following the retirement of Dr. Theresa Tam, who became a prominent figure during the pandemic through her regular updates on public health measures. Tam served for eight years and played a pivotal role in guiding Canadians through the evolving landscape of public health advice and epidemiological data.

Reimer’s experience as the chief medical officer for the Winnipeg health authority and her leadership of Manitoba’s COVID-19 vaccination task force will inform her approach. Her appointment comes at a critical juncture for Canada’s health system as the nation grapples with a resurgence of vaccine-preventable diseases and the ongoing repercussions of the illegal drug crisis.
Addressing Vaccine Hesitancy
Health Minister Marjorie Michel emphasised the importance of Reimer’s leadership, particularly in light of alarming trends such as the recent measles outbreak that has led to Canada losing its measles elimination status held since 1998. “We need partnerships from community leaders all the way up to the federal government,” Reimer stated, underscoring the need for collective action against vaccine hesitancy.
Reimer’s personal connection to the measles outbreak, having grown up in a region affected by vaccine hesitancy, gives her a unique perspective. She remarked on the disease’s highly infectious nature and the role misinformation plays in its resurgence, noting, “It’s not surprising that measles cases are on the rise, given how incredibly infectious the disease is.”
The Role of Information in Public Health
Reimer’s vision for public health also encompasses a commitment to ensuring that Canadians are receiving trustworthy information, especially as misinformation increasingly permeates various platforms. Recent statements from health officials indicate that misleading information is not confined to social media; it has infiltrated broader discussions about health outcomes and public safety.
As Canada seeks to navigate these challenges, Reimer emphasised the importance of maintaining a robust national stance on health information. “Canada needs to stand on its own,” she said, while acknowledging the contributions of American health professionals. “There are still really amazing people in the American system doing wonderful work.”
Why it Matters
Dr. Joss Reimer’s appointment comes at a crucial time in Canadian public health, as the nation confronts a myriad of challenges exacerbated by misinformation and a decline in public trust. Her proactive approach to rebuilding relationships with communities and ensuring the dissemination of accurate health information will be vital in restoring faith in health institutions. As Canada navigates the complex aftermath of the pandemic, Reimer’s leadership could be key to safeguarding the health and well-being of Canadians for years to come.
