Twenty-one children were taken to hospital after a thunderstorm ripped through a camp in northeast Edmonton Tuesday night.
The storm swept through Our Lady Queen of Peace Ranch at around 9:30 p.m., knocking over tents.
"There's been some scrapes and bruises, cuts and abrasions, that sort of thing for injuries," said District Fire Chief Darrell Dublanko. "There hasn't been any significant injuries, life-threatening or anything like that."
The camp is in a valley and the storm whipped through in a matter of several minutes, Dublanko said.
Environment Canada issued a severe thunderstorm warning almost an hour before high winds blew down tents and injured some children at a summer camp on the outskirts of Edmonton.
William Doherty, CEO of Our Lady Queen of Peace Ranch, says the charity camp for disadvantaged children is not wired for Internet weather updates.
About 200 children were at the camp at the time. All have been accounted for and have been moved inside the main building.
"They're happy and have their sleeping bags inside now, instead of in the tents," Dublanko said.
According to the website, the camp gives children who face physical, mental, financial or emotional challenges a chance to experience the outdoors.
