An autopsy was performed Friday on a 13-year-old South Korean visa student who died on a school ski trip earlier this week, but the OPP says it can't release the results.

"The cause of death has to be released by the coroner's office," OPP Const. Peter Leon told on Friday.

"James" Boo Sung Moon, a Grade 8 student at Richmond Hill's Trillium Woods Public School, was skiing at Snow Valley ski resort in Barrie, Ont., on Wednesday afternoon.

He was skiing on a beginner hill -- known as "Family Hill" -- when he apparently lost control and struck a tree. Police were called to the scene of the accident around 1:15 p.m.

The boy was taken to Barrie's Royal Victoria Hospital, but succumbed to his injuries.

Leon said the ski resort is known for the services it offers to less experienced skiers.

"In all honesty, it is geared to first-time and novice skiers and the hill that this young lad was on was actually referred to as a family hill," Leon said in a phone interview on Friday morning.

"There's no incline whatsoever, it's a very gradual hill and unfortunately he was inexperienced. This was only the second time he had been skiing and as a result of losing control, he went into the trees and struck a tree."

Leon said the ski resort rents all types of ski equipment to skiers, including ski helmets, although the boy was not wearing one when he lost control.

"It's a very, very unfortunate set of circumstances obviously, not only for the family but also for the classmates of this young lad," Leon said.

According to the Snow Valley website, helmets can be rented for $8 per day.

York Region District School Board spokesperson Lucia Cascioli told that parents were informed about the risks that come with skiing, as well as the precautions and equipment they would need to consider for their kids.

"In this particular instance, the parents were provided with letters to go home and the various forms that needed to be signed," she said in a phone interview on Friday morning.

Parents had to provide informed consent for their children to take part in the trip and had to fill out a skills classification agreement, Cascioli said.

Cascioli said an assembly was held at Trillium Woods Public School on Thursday, in which students had a chance to discuss their feeling about the Grade 8 boy's death.

"They were able to, for example, write down their thoughts about James and memories that they had about James, as a method of being able to express themselves and being able to express the emotions that they were going through," she said.
