Dr. Joss Reimer, appointed as Canada’s new chief public health officer, has outlined her primary goals: combating health misinformation and rebuilding the public’s trust in health institutions. In a recent interview, she emphasised the pressing need for proactive measures against false information, acknowledging the significant erosion of trust that occurred during the COVID-19 pandemic.
Prioritising the Fight Against Misinformation
During her inaugural interview following the announcement of her three-year appointment, Reimer highlighted the rapid evolution of health misinformation as a critical challenge. “One of the biggest challenges with health misinformation is the speed at which it changes,” she remarked, noting that fabrications can spread quickly and widely.
The pandemic has left many Canadians questioning the reliability of health information. Reimer pointed out the hardships faced by individuals during this time: job losses, separation from loved ones, and the difficult decisions made by health officials. “We have a lot of trust-building that we’re going to need to do that’s going to take years,” she stated, recognising the long-term effort required to restore confidence in public health messaging.
A Legacy of Public Health Leadership
Reimer steps into her new role following the retirement of Dr. Theresa Tam, who became a prominent figure in Canadian households as she provided essential updates during the pandemic. With experience as the chief medical officer for the Winnipeg health authority and as a leader in Manitoba’s COVID-19 vaccine strategy, Reimer is well-prepared to navigate the complexities of public health in Canada.

Health Minister Marjorie Michel acknowledged the timeliness of Reimer’s appointment, highlighting the current resurgence of vaccine-preventable diseases such as measles and the ongoing challenges posed by the illegal drug crisis. “We are facing the harmful impacts of false health information,” Michel noted, underscoring the urgency of Reimer’s mission.
Addressing Vaccine Hesitancy and Outbreaks
Reimer’s unique perspective on the current measles outbreak stems from her roots in a small town experiencing vaccine hesitancy. “We need to have partnerships from on the ground, from community leaders all the way up to the federal government,” she said, advocating for a collaborative approach to tackle vaccine reluctance.
Canada’s recent loss of its measles elimination status, which it had maintained since 1998, has alarmed public health experts. Reimer expressed concern over the infectious nature of measles and the prevailing climate of misinformation contributing to the rise in cases, stating, “It’s not a shock that measles cases are on the rise.”
Reaffirming Canada’s Commitment to Public Health
In an era when misinformation can proliferate unchecked, Reimer stressed the importance of reliable information in public health. She suggested that Canada must establish its own credibility and trustworthiness in health communications, especially in light of the challenges posed by external influences. “I know that there are still really amazing people in the American system doing wonderful work,” she acknowledged, while advocating for a distinct Canadian narrative.

Reimer’s extensive background, including research on sexually transmitted diseases and drug-related harms, positions her well for the challenges ahead. Nancy Hamzawi, president of the Public Health Agency of Canada, expressed her confidence in Reimer’s capabilities, 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.”
Why it Matters
The appointment of Dr. Joss Reimer as chief public health officer comes at a crucial juncture for Canada, where trust in health institutions is precariously low. Her commitment to combat misinformation and restore public confidence is essential not only for the immediate health landscape but also for long-term societal resilience. As Canada faces the dual challenges of infectious diseases and misinformation, Reimer’s leadership could be pivotal in steering the nation towards a healthier and more informed future.
