Google Rolls Out ML Age Estimation in Canada Using Search History

Google is gradually deploying machine-learning age-assurance technology in Canada that analyzes search patterns and YouTube viewing behavior to estimate whether a signed-in user is under 18. Flagged accounts automatically get YouTube wellbeing features, blocked adult apps in Google Play and a disabled Maps Timeline, while misclassified adults must verify age with a government ID or selfie.

• System relies on existing search and YouTube viewing signals, no new data collected
• Accounts estimated as under 18 get YouTube protections, blocked adult Play apps and no Maps Timeline
• Misclassified adults can correct age by uploading a government ID or selfie
• Rollout is gradual across YouTube, Google Play and Google Maps accounts in Canada
