Toronto — Leading international researchers, including Canadian scholars, are calling for urgent, system-wide intervention to protect children and youth from the escalating mental health risks posed by unchecked social media and digital platform use. Their findings, published in a comprehensive series by The Lancet, argue that placing the burden on parents and young users—through measures like screen-time restrictions—is no longer sufficient.
Instead, the authors advocate for a fundamental shift in accountability, urging governments and technology companies to take responsibility for designing digital environments that safeguard the well-being of minors.
Rethinking Digital Determinants of Health
Jay Shah, Canada Research Chair in Responsible Health Innovation at the University of Toronto and co-author of the Lancet series, emphasizes that viewing technology’s impact through an individual-choice lens misses the broader picture. “It’s easy to think about how technology impacts our health as being about our individual choices,” he said in a recent interview. “One of the things we really want to get across is that that’s not the right way to think about it.”
The papers highlight how modern digital platforms are intentionally designed to maximize user engagement, often at the expense of healthy behavioural boundaries. Features such as infinite scroll, algorithm-driven content feeds, and push notifications are engineered to prolong usage, contributing to addictive patterns and psychological distress among young people.
These design strategies, coupled with data-harvesting business models, exploit cognitive vulnerabilities in developing minds. As Shah explains, the goal isn’t to vilify technology itself—but to challenge the structures that profit from prolonged exposure, particularly among vulnerable populations.
Evidence of Harm and Benefit
An umbrella review of 2,790 studies, included in the Lancet series, reveals a troubling link between heavy digital media consumption and increased rates of depression, anxiety, disrupted sleep, and sedentary lifestyles among youth. However, the analysis also acknowledges potential benefits tied to moderate use, such as enhanced social connection, access to educational resources, and improved self-esteem when engagement is intentional and positive.
“It underscores the importance of looking at both the patterns of engagement and the type of content consumed,” Shah notes. “Not all screen time is created equal.”
Despite mounting evidence, major tech firms continue to resist regulatory pressure, often citing a lack of definitive causal links. Yet the researchers behind the Lancet series argue that the sheer scale of exposure—and the disproportionate vulnerability of children—justifies precautionary action, even in the absence of absolute proof.
Global Momentum Toward Regulation
Countries worldwide are beginning to act. Australia has already implemented age-based restrictions on social media access, while nations like Canada are advancing their own legislative frameworks. Two key bills currently under consideration—Bill C-34, the Safe Social Media Act, and Bill C-36, the Protecting Privacy and Consumer Data Act—are praised by Shaw for aligning closely with expert recommendations.
If passed, these laws would establish a Digital Safety Commission tasked with overseeing tech industry practices and restricting social media use for individuals under 16. Importantly, they would permit exceptions for platforms that can demonstrate robust child-protection measures.
“That logic of incentivising digital media companies to prove safety is central to solving this crisis,” Shaw says. “We recognise that digital tools offer immense value—for learning, creativity, and community-building. A blanket ban isn’t the answer. But neither is doing nothing.”
Young Voices Call for Accountability
The Lancet series draws strength not only from academic rigor but also from personal narratives. Six young adults, aged 23 to 30, formed a youth advisory group whose lived experiences shaped the discourse throughout the project. Among them is Yifan Zhou, a Canadian advocate who reflects on both the promise and peril of today’s digital landscape.
“Social media connects me with friends across continents and opens doors to knowledge I might never have accessed otherwise,” Zhou shares. “But I’ve also seen peers struggle with loneliness, anxiety, and unhealthy comparisons sparked by what they see online.”
Her concerns deepen when she speaks of a family member who endured years of silent exploitation by an online predator—an experience hidden due to stigma and inadequate support systems. “They didn’t know it wasn’t normal,” Zhou recalls. “There were no safeguards, no education, and no one to turn to.”
Medical professionals echo these sentiments. Dr. Michael Cheng, a psychiatrist at the Children’s Hospital of Eastern Ontario and the CHEO Research Institute, observes a stark evolution in patient priorities over the past decade. Where once hospitalised youth asked about visiting hours or phone calls home, many now inquire whether they’ll be allowed to keep their phones during treatment.
“I remember 10, 15 years ago, advocates felt like they were shouting into the void,” Cheng reflects. “Now there’s a global reckoning happening—and perhaps, finally, a path forward.”
Looking Ahead: Co-Creation and Change
While acknowledging that regulation moves slowly compared to technological advancement, Zhou remains cautiously optimistic. “This report gives me hope,” she says. “And beyond policy, I see young people stepping up—demanding transparency, holding corporations accountable, and co-designing safer digital futures.”
For policymakers, parents, and practitioners alike, the message is clear: protecting youth in the digital age requires more than good intentions. It demands structural reform, ethical innovation, and unwavering commitment to placing child welfare above corporate gain.
Why it Matters
The rise of problematic social media use among children and adolescents represents one of the defining public health challenges of our time. Left unaddressed, it threatens to erode mental health outcomes, deepen inequalities, and undermine the very foundations of healthy development in an increasingly connected world. By shifting focus from individual responsibility to systemic accountability—through thoughtful legislation, platform redesign, and youth empowerment—we stand at a crossroads where proactive intervention can prevent irreversible harm. This moment calls not for incremental tweaks, but bold, coordinated action rooted in science, empathy, and foresight.
