OPP told CTV News Ottawa that at least one person was airlifted to hospital with serious, life-threatening injuries.
Ottawa Fire Services said one person was extricated from a vehicle that had caught fire. The fire was quickly extinguished.
Four other people were transported by Ottawa Paramedics, according to Ottawa Fire Services. CTV News Ottawa has reached out to paramedics for more information about the condition of the injured.
