Chaperones at St. David Catholic Secondary School near Waterloo, Ontario in Canada had 15 of its teenagers go missing on a school trip intended to teach "survival and backcountry camping" in a national park. Thankfully, the children were found Friday morning — but they were still missing for about 12 hours. Which... what?

"Ontario Provincial Police were searching for the group of teens, between 16 and 17-years-old, after they were separated from the main hiking group around 5 p.m. yesterday," reported Canada's CBC News, which updated their story to read that the high-schoolers were found around 5 a.m. this morning. 

Bruce National Park is located in Southern Ontario. And obviously, a school losing 15 of its students — even its older ones — in the wilderness for that long is cause for concern, not just for liability but, you know, because there are bears and rattlesnakes in Bruce National Park. Compared to Yosemite and Yellowstone parks in the U.S., which have seen some freak accidents and deaths last year, Bruce seems relatively safe. The biggest concern was reportedly the weather. "The source said chilly temperatures on the Bruce Peninsula is what prompted concern over the missing teens," CBC News reports. According to temperature forecasts, it's about 2°C (around 35° F) in Bruce Park, though you'd think that the teens being "missing" on the school's watch — and that the cops had to be called in for a search — would be the factor that would actually "prompt concern." 

But maybe they're built sturdier and steelier up there in Canada. Ontario Provincial Police said there was nothing to worry about the whole time, as CBC News reported:

OPP [said] they have been advised there are no concerns about the teenagers staying in the wilderness overnight because the school trip is focused on survival and backcountry camping.

All the children were found, and there were no reports of any injuries.
