A Canadian water park closes down following an electrical shock incident that sends 12 children to hospital, multiple outlets report. According to officials, the incident happens when a group of middle school students touch a metal railing while they are waiting in line for a ride. The reports say the children receive electrical shocks and are taken to medical facilities for assessment and treatment. The park’s closure follows the incident as authorities and the operator review safety conditions and determine the cause of the shock. While details about the specific ride, the timing, and the extent of injuries are not provided in the excerpts, the accounts consistently describe the same sequence: students in a queue contact a metal railing, an electrical shock occurs, and 12 children are hospitalized. The park remains closed as investigations proceed. Further information from officials is expected as safety checks and inquiries continue.
