Ottawa Public Health looks to counter health disinformation online
The agency is moving beyond passive website information to actively monitor, correct and prevent false health claims from spreading through social media and digital communication channels.
Ottawa Public Health is taking a significant new step to combat health disinformation online, according to a report from CTV News Ottawa, in an effort that reflects growing concern among public health officials about the dangerous consequences of false medical claims. The agency is no longer approaching the internet as a passive broadcasting tool where residents must seek out reliable information, but rather as a challenging battlefield where misinformation must be actively monitored, challenged and prevented. The initiative is expected to involve a more visible digital presence, the rapid correction of false claims, partnerships with community organizations and the creation of digital content that promotes evidence-based health advice in plain and accessible language. OPH officials have reportedly framed the campaign as a core public health intervention, not simply a communications exercise. The concern is that health misinformation is not an abstract online problem but one that has led people to skip vaccinations, avoid proven treatments, use unregulated remedies and follow dangerous advice during a health crisis. The CTV report noted that false narratives around vaccines, chronic disease, treatments and public health guidance continue to circulate widely on social media, often reaching more people than official messages. As a result, Ottawa Public Health’s new strategy is being designed to treat online misinformation as a kind of environmental hazard, one requiring the same seriousness as a contaminated water supply or an outbreak of infectious disease. The goal is to ensure residents, regardless of how they access information online, have the ability to encounter credible, science-based content and are better equipped to recognize false and misleading health claims before they act on them.
The push to counter health disinformation comes after years of lessons learned from the COVID-19 pandemic, when Ottawa Public Health and other health agencies across Canada struggled to keep up with the massive volume of misleading content circulating on social media platforms. During that period, false claims about masks, lockdowns, vaccines and unproven medical treatments spread faster than scientists could correct them, and health authorities found themselves in a reactive position, constantly trying to put out fires that had already ignited in private Facebook groups, TikTok videos and chat applications. The new strategy is designed to break that cycle by being more proactive. Public health officials reportedly realized that an official website post was no longer sufficient, as many residents now receive most of their health information through social media feeds, search engine results and viral posts shared by friends and family members. The CTV News report describes a broader recognition that misinformation represents a significant public health threat that can undermine years of work in preventive medicine. Health disinformation has been linked to lower vaccine uptake, hesitancy toward routine childhood immunizations, dangerous self-medication practices and confusion about common health directives. It has also contributed to broader mistrust in government institutions and the medical profession. Social media algorithms, which reward engagement and often amplify content that generates fear and outrage, have made this problem worse, as have artificial intelligence tools that can generate realistic-looking images, videos and fake audio that appear to come from credible doctors or health officials. Ottawa Public Health’s decision to invest in countering these forces is a recognition that protecting health in the modern era requires engaging with the digital world directly.
The heart of the new initiative, according to the CTV News report, lies in a more robust and specialized response system within Ottawa Public Health. The agency will expand its digital communications capacity, adding staff with expertise in monitoring misinformation, designing educational campaigns and using digital advertising to place credible health information inside the same spaces where misinformation is likely to appear. A major part of the approach will involve real-time monitoring of public social media conversations to identify emerging health myths before they become widespread. When a harmful claim is identified, OPH will respond quickly with clear, fact-based corrections, often in the form of short videos, infographics or accessible text posts that are easy to share. The agency is also examining the use of “prebunking” techniques, a strategy borrowed from psychological research that involves familiarizing people with the techniques used by misinformation creators, so they are less likely to be manipulated later. Rather than waiting to debunk a false story once it has already spread, prebunking tries to “inoculate” the public by explaining common myths, logical fallacies and production tactics in advance. The plan includes digital advertising campaigns aimed at specific communities and demographics, ensuring that evidence-based health information appears prominently in search results and social media feeds. The agency is also expected to work alongside social media platforms, flagging content that poses a serious health risk, while remaining mindful of the importance of free expression and avoiding the appearance of political censorship. At its core, the strategy reflects a simple but important idea: that public health advice should be visible and persuasive enough to reach people at the moment they are searching for answers.
Ottawa Public Health’s new approach extends beyond its own communications team, emphasizing partnerships with community organizations and trusted front-line figures. According to the report, the agency recognizes that many residents are more likely to follow health advice from a family doctor, religious leader, local pharmacist or teacher than from a government social media account. As a result, the initiative includes plans to collaborate with physicians, nurse practitioners, public health nurses, community health centres, school boards and ethno-cultural organizations to distribute reliable information and respond to misinformation in local languages and cultural contexts. The agency is reportedly exploring ways to train community members to become “health information ambassadors,” giving them the tools and knowledge to recognize common misinformation themes and discuss them constructively with neighbours, friends and family. This is particularly important in communities where social media use is concentrated in closed or private groups, making it impossible for public health officials to directly join or monitor those conversations. Instead, building capacity within those communities is seen as a more realistic and respectful strategy. The initiative also emphasizes listening. OPH plans to conduct surveys, focus groups and town-hall sessions to better understand why some residents are hesitant to trust official guidance, what types of misinformation they have encountered, and what formats and messengers would be most effective in earning their confidence. This conversational and non-judgmental approach is intended to address misinformation at its roots, rather than simply attacking it after it has already taken hold. By empowering trusted individuals and organizations, Ottawa Public Health hopes to create a network of credible voices that can reach audiences that government agencies often cannot.
Despite the enthusiasm behind the new strategy, public health experts cited in the CTV News report caution that countering health disinformation is an extremely difficult and ongoing challenge. One major hurdle is the sheer scale and speed of online content creation. A single false tweet, TikTok video or Facebook post can go viral within hours, while a carefully fact-checked response may take many more hours to research, write, approve and publish. By the time the correction appears, the misinformation may already be deeply embedded in certain communities. Another concern is the so-called “backfire effect,” or the possibility that some people become more entrenched in their beliefs when confronted with information that challenges them. This is especially true when the source of the correction is a government agency that some residents already distrust. OPH officials are reportedly aware of this dynamic and are designing messaging that avoids sounding condescending or dismissive. The tone of the campaign will be calm, respectful and empathetic, focusing on explaining the evidence in plain language rather than shaming those who were deceived. There are also issues related to the mental health and safety of public health staff. During the pandemic, public health officials in Ottawa and across Ontario experienced harassment, threats and personal attacks, sometimes in response to their online presence. Any new strategy that invites more public engagement, particularly around controversial subjects such as vaccines, must include measures to protect staff and ensure that responses remain professional and composed. The report also raises the broader policy question of what role government should play in requesting that technology companies remove or down-rank certain content. While there is little controversy about removing content that is immediately dangerous, such as instructions for using unapproved drugs, there is more concern about a public health agency becoming a judge of broader public debate. Striking the right balance between acting quickly and preserving credibility will be a delicate challenge for Ottawa Public Health throughout this process.
The initiative is expected to be rolled out in phases over the coming months, beginning with the development of internal capacity and the establishment of key partnerships with community organizations, clinicians and digital platforms. Ottawa Public Health will also evaluate the effectiveness of its efforts, using both online engagement data and real-world health outcomes such as vaccination coverage, participation in screening programs and the public’s understanding of important health topics. If successful, the approach may serve as a model for other health agencies in Ontario and across Canada, many of which are watching closely to see whether this style of proactive digital public health communication can produce measurable improvements. In the meantime, public health officials are encouraging residents to be mindful about the information they consume and share online. They recommend verifying any health-related claim with an official source such as Ottawa Public Health, Health Canada or the Ontario Ministry of Health, and consulting a doctor, pharmacist, nurse or family health team when uncertain. Residents are also being asked to avoid sharing dramatic health headlines without checking whether they are true, and to feel comfortable reporting suspicious online health content to the appropriate authorities. The broader message from the CTV News article is that health misinformation is a community-wide problem that cannot be solved by government action alone. Technology companies, health professionals, community leaders and ordinary residents all have a role to play in promoting reliable, science-based health information. Ottawa Public Health’s new strategy is an acknowledgment that the digital information environment is not separate from public health, but central to it, and that the city must continue to adapt its methods in order to protect the well-being of every resident in the face of an evolving and highly connected information landscape.
