The Ontario Provincial Police has launched an investigation into the death of Jeremiah Perry who died in early July while on a Toronto District School Board (TDSB) canoe trip to Algonquin Park.

The OPP's Criminal Investigation Branch is on the case, which will be overseen by Det.-Insp. Peter Donnelly.

Last week, the school board revealed that the 15-year-old did not pass a swim test. TDSB protocol requires that all students pass a swim test in order to go on such a trip.

The board also said that 15 of the 32 students who went on the multi-day trip in the provincial park near Huntsville, Ont., had failed their swimming tests. Two students also had no documentation. 

Perry was swimming in Big Trout Lake on July 5 when he went beneath the water and disappeared. Police later recovered his body after a large scale search of the area.

The OPP didn't reveal any additional details on the investigation, only stating that they are looking into Perry's death.
