PMID 41397414WHAT IT FOUND
Canadian parents and adults overwhelmingly believe schools, governments, and tech companies must help children use screens safely.
However, the effort is fragmented: policies are inconsistent, sectors rarely collaborate, and federal leadership is largely absent despite growing media concern.
Key findings
01Approximately three-quarters of Canadian adults agree that schools, governments, and tech companies need to help children use screens safely and in moderation.
02Most Canadian school boards ban or restrict mobile device use during class, but policies vary widely and many boards lack social media access rules.
03There is a lack of coordination between health, education, and advocacy sectors, with weak connections between key players and no unified national strategy.

What it does not show
The opinion survey was not psychometrically tested and may be subject to social desirability bias. The school board scan only included the top 10% largest boards, so results may not apply to small or rural boards. The environmental scan was conducted by a single researcher due to budget constraints, lacking double-screening. Media analysis relied only on headlines, which may be sensationalized or clickbait. The network analysis relies on self-reported connections and may miss isolated key players.
Declared interests
Funding was provided by the Children's Hospital of Eastern Ontario, ParticipACTION, and the Healthy Active Living and Obesity Research Group. Authors hold volunteer leadership roles in ParticipACTION and the Sedentary Behaviour Research Network, organizations that advocate for reduced screen time and sedentary behavior.
The easy way to misread this
Do not interpret the high percentage of school boards with device bans as evidence that screen time is being effectively managed for health outcomes. The paper explicitly states that the effectiveness of these new policies is unknown and that the lack of coordination between sectors means these efforts are currently fragmented and underachieving.
