Canada’s newly appointed chief public health officer, Dr. Joss Reimer, has made it clear that addressing health misinformation and rebuilding public trust will be her primary objectives. Announced on Friday, Reimer’s three-year tenure begins on April 1. Acknowledging the challenges posed during the COVID-19 pandemic, she emphasised the importance of a proactive stance by the federal government to counteract false narratives that have proliferated in recent years.
Rebuilding Trust Post-Pandemic
In a detailed interview, Reimer expressed her concerns regarding the erosion of public trust in health institutions, which she believes was exacerbated by the pandemic’s fallout. “The difficulties faced by many, from job losses to separation from loved ones, have made it challenging for people to trust the information they receive,” she stated. “Rebuilding that trust will take time and effort, but it is absolutely essential.”
The pandemic brought public health officials into the limelight, with Dr. Theresa Tam, Reimer’s predecessor, becoming a familiar figure as she provided critical updates throughout the crisis. Following Tam’s retirement in June after eight years, Reimer steps into this pivotal role at a time when the need for clear and reliable health messaging is more crucial than ever.
Key Challenges Ahead
Reimer’s experience as Manitoba’s chief medical officer and her leadership role in the province’s COVID-19 vaccination efforts position her well to address the complex challenges facing Canada’s public health landscape. Health Minister Marjorie Michel highlighted the severity of current issues, noting a resurgence of vaccine-preventable diseases like measles, as well as threats from avian influenza A (H5N1), HIV, and tuberculosis.

“Canada is grappling with the ongoing impacts of the illegal drug crisis, compounded by the detrimental effects of widespread misinformation,” Michel remarked. The urgency of the situation is underscored by Canada’s recent loss of its measles elimination status, a status held since 1998, which experts have deemed alarming.
A Personal Perspective on Vaccine Hesitancy
Reimer brings a unique viewpoint to the ongoing measles outbreak, recalling her roots in a small town significantly affected by the crisis. “We’ve observed a concerning level of vaccine hesitancy, and it’s essential that we forge partnerships from community leaders to federal authorities to tackle this issue effectively,” she explained.
The highly contagious nature of measles, combined with increasing misinformation, makes the situation even more pressing. “It’s not surprising that we’re witnessing a rise in cases, given how incredibly infectious measles is,” she added.
Establishing Independent Health Messaging
In remarks concerning the influence of misinformation, Reimer pointed out that the challenge extends beyond social media. During a previous conversation, Minister Michel noted that the reliability of American health institutions has diminished, particularly following the previous U.S. administration’s disinvestment in scientific research and promotion of false narratives regarding vaccines.
Reimer affirmed the necessity for Canada to establish its own credible health information system, stating, “While there are still dedicated professionals in the American system, we must ensure that Canadians receive trustworthy health information that stands on its own.”
Why it Matters
As Dr. Joss Reimer embarks on her new role, the implications of her leadership extend beyond mere health statistics. The ongoing battle against misinformation is critical not only for public health but for nurturing a society that values science and trustworthiness in governance. By prioritising transparency and community engagement, Reimer’s agenda could pave the way for a more resilient health system, fostering a culture where public confidence is restored and maintained—an essential cornerstone for effective public health policy in Canada.
