The Canadian government has thrown down a gauntlet to the world’s tech giants with legislation that would bar anyone under 16 from holding social media accounts unless companies can prove they offer safe environments for children. The bill, tabled by Culture Minister Marc Miller, envisages fines of up to three per cent of a firm’s global revenue or ten million Canadian dollars, and the creation of a dedicated regulator to enforce the new rules. Viewed from Ottawa, the move is an overdue assertion of public authority over platforms that have, for years, failed to shield minors from cyberbullying, grooming and exploitative content. Yet even within Canada, British Columbia’s attorney general Niki Sharma has called the federal initiative merely a “promising step”, arguing it should be extended to cover AI chatbots and other digital harms that reach far beyond traditional social feeds.

Across the Atlantic, European policymakers are torn. Sweden’s government is pushing a 15-year age limit, but critics warn that such a threshold risks becoming a placebo. In Stockholm’s public debate, child rights advocates contend that simply locking younger teens out of certain platforms does nothing to disappear predators or make the remaining digital spaces safe; it may even shift attention away from the structural reforms the platforms themselves must adopt. In Berlin, the German Ethics Council has similarly cautioned against a blanket ban, instead endorsing a graduated protection model that restricts access to harmful content based on age-appropriate design. The council’s stance reflects a growing consensus among European ethicists that nuanced, risk-based frameworks may prove more effective than rigid age gating.

Mounting evidence of harm strengthens the case for action. A decade-long study from Melbourne’s Murdoch Children’s Research Institute, tracking 1,200 schoolchildren, found that those spending at least two hours daily on social media were at small but increased risk of depressive symptoms and anxiety—a correlation particularly pronounced among girls aged 12 to 13. Meanwhile, Snapchat’s own recent tightening of features for 13-to-15-year-olds—restricting content sharing to mutual friends and hiding engagement metrics—illustrates how self-regulation is already scrambling to pre-empt state intervention, though critics dismiss such measures as cosmetic.

The debate extends beyond mental health. Argentine commentators, marking the World Day Against Child Labour, point to a parallel crisis: the rise of underage influencers who are exposed to commercial exploitation behind the veil of a scroll. This Latin American perspective underscores that digital harm is not just about psychological distress but also about economic and physical vulnerability, demanding a regulatory response that reaches into the shadow economy of content creation. As governments from Canberra to Buenos Aires watch Ottawa’s move, the emerging consensus is that no single age limit can substitute for a comprehensive online safety strategy. The real test will be whether the Canadian experiment can evolve into a layered defence that combines robust enforcement, platform accountability, and digital literacy—or whether it merely relocates the problem to darker corners of the internet.
