Facebook brings its messaging app for kids to Canada despite experts' concerns

A version of Facebook'spopular text and video messaging app aimed atchildren under the age of 13is now available in Canada,Facebook said on Friday, despite concerns from advocatesthat children are ill-equipped to use social media at such a young age.

Messenger Kids was first made available in the United Statesat the end of last year, and has been pitched as a means for parents to let their kids chat with close friends and family in a safer and more controlled environment than other messaging apps.

However, Messenger Kidshas attracted criticism from some experts who argue that young children are not yet able to navigate the complexities of privacy and social etiquette online, and that an increase in screen time could interfere with the development of healthy relationship skills that otherwise come from face-to-face interactions.

In January, more than 100 child advocates, civil society groups, medical expertsand other individualssigned a letter to Facebook CEO Mark Zuckerbergoutlining their concernsand asking that the app be discontinued.

Facebook saysthat it developed the app in collaboration with parents and experts including the Canadian digital literacy organization MediaSmarts and has taken their feedback into account. Some of those experts and their organizations have reportedly received research funding or donations from Facebook in recent years.

Unlike the standard version of the service, Facebook saysthat Messenger Kids does not include ads, and that kids' accounts are separate from standard Facebook accounts. It also allows parents to approve contactsand limit when the app can be used.

The Public Interest Advocacy Centre, a Canadian non-profit,also wrote a letter to Zuckerberg and Facebook's Canadian head of public policy, Kevin Chan, asking that the app not be released.

The centre's director, John Lawford, argued that Facebook has not adequately explained how it will use the information it collects whenkidsuse the app. He also wrote that, "by encouraging children under 13 to use its services, Messenger Kids can capture kids young and keep them their whole lives."
