The pleasure police have struck again, this time in Canada (emphasis mine).

As the first big snowfall greeted Canada's most populous city this week, schools encouraged students to engage in kinder, gentler activities, such as building snow forts or riding sleds.

"We don't encourage people to throw things at other people - rocks, sticks or snow," Maureen Kaukinen, system superintendent for the Toronto District School Board, told Reuters on Tuesday.

While snowball fights are expected to continue to rage off the schoolyard, Kaukinen said schools cannot condone acts of violence.
