The bill would require social media services to block account creation for users under 16. The definition covers traditional social media platforms, livestreaming services, and adult content services focused on user-shared content, per CBC News.

That restriction is not necessarily permanent for most platforms. Services could apply to the proposed Digital Safety Commission for an exemption if they implement what officials described as adequate safeguards for children. The criteria for what qualifies would be set through regulations after the bill passes, not by the bill itself, officials said.

Adult content services are excluded from that pathway entirely. No level of child-safety investment qualifies them to retain users under 16, CBC News reported.

Both when the age restriction would come into force and how long exemptions would take to be granted remain unclear, CBC News reported. The practical effect: the restriction will apply most broadly in the period before the Commission has written its standards and assessed anyone, meaning the age limit functions as an absolute floor until a platform earns its way off it.

Nothing in the bill changes platform access today. Parliamentary passage comes first, and officials estimate the Digital Safety Commission could take 18 months to stand up after the bill becomes law, according to CBC News. Regulation-writing and exemption decisions follow after that. Real-world impact for users under 16 is measured in years, not months.

The Commission's mandate goes well beyond exemptions. Once operational, it would review platforms' publicly filed Digital Safety Plans, conduct audits, issue compliance orders, field user complaints, and develop the guidance that ultimately defines what adequate child safeguards look like, the government announced. Penalties for violations would reach $10 million or 3% of a company's gross global revenue, whichever is greater, with multiple penalties available for sustained non-compliance, per CBC News.

The bill also includes a privacy-preserving process to give accredited researchers access to certain platform data, the government announced. That provision matters because it could eventually produce independent evidence on whether any of these measures actually protect children, though it too depends on the Commission being up and running.

The under-16 restriction is the bill's headline, but its broader platform obligations apply whether or not a service seeks an exemption.

All regulated services, including social media platforms and AI chatbot services, would face three binding duties. A Duty to Protect Children requires age-appropriate design features. A Duty to Act Responsibly covers risk mitigation, labelling of AI-generated content, and providing accessible blocking and flagging tools. A Duty to Make Certain Content Inaccessible applies to two specific categories of harmful material, the government announced.

That third duty is where the bill draws its sharpest line. Seven categories of harmful content fall within scope: material used to bully children, content inducing self-harm, hatred, violence, terrorism, child sexual abuse material, and non-consensual intimate imagery including sexualized deepfakes. The last two are treated differently from the rest. Platforms would be required to make those categories inaccessible outright, not merely manage the risk of exposure. The government's rationale: a single piece of content in either category can cause substantial and lasting harm to the person depicted, making risk reduction an insufficient response, the government announced.

The other five harmful content categories fall under the Duty to Act Responsibly. Platforms would need to address them systematically, without facing an absolute removal obligation for every instance.

AI chatbot services carry their own version of that duty. They would be required to implement crisis-response measures when a user expresses suicidal ideation or an intention to commit an act that could cause death or serious bodily harm, CBC News reported. The bill would not require companies to report those interactions to police.

The government points to two figures to justify the bill's design-level approach: one in four Canadian youth aged 12 to 17 report experiencing cyberbullying, and police-reported incidents of online child sexual abuse and exploitation have increased significantly in recent years, per the government's bill summary. The argument is that content moderation after the fact isn't enough; accountability needs to be built into the platform's design from the start.

Parliament still has to pass the Safe Social Media Act. Its political durability is untested. The previous attempt collapsed, and while stripping out the Criminal Code amendments removes one major objection, passage is not guaranteed.

The regulations will likely matter more than the headline age limit. When the Digital Safety Commission eventually writes the standards defining what counts as sufficient safeguards, that threshold will determine whether the under-16 restriction functions as a meaningful floor or a bar most major platforms can clear without substantially changing how they operate.

Australia was the first country to set a minimum account age for platforms including TikTok, YouTube, Instagram, and Facebook, doing so late last year, CBC News reported. No jurisdiction has run one of these regimes long enough to produce clear evidence on whether they reduce harm or shift where children encounter it. The researcher-access provisions in Bill C-34 could eventually generate that data, if the Commission gets built.
