Those statistics come from survey data. The Canadian school health behaviour survey is one really important source of data, along with work that Statistics Canada does to look at the patterns of behaviour among our children in the after-school time period.
Of course, there are many factors that contribute to that. For instance, there's kids' interest in video games and the fact that, in some cases, we are more concerned about the safety of our children and therefore tend not to promote, as much as we may have in the past, their running around and playing outside in parks, etc. So there are a number of sociological and behavioural studies that are being done, given those realities of modern life, at how we can shift that paradigm. How can we start to encourage our kids, particularly during that critical after-school time period, to become more active, to be engaged in safe and active play, either through school programs or in their communities? That, in particular, is an important part of the work that we are doing at the Public Health Agency, with our counterparts in provincial-territorial governments, working with the education sector and the sports and recreational sector to provide guidance to communities and parents around allowing their kids to play safely. It's an important priority for us and will continue to be over the next number of years.
