A school bus with a child on board was involved in a collision Thursday evening near the Ministikwan First Nation.
The child was the son of the bus driver.
Loon Lake RCMP say a Ford Focus hit the bus as it was coming off a side road, sending the bus spinning into the ditch.
Police say the car was heavily damaged and three of the occupants required medical attention.
The bus driver and his son were not hurt.
Mounties say road and weather conditions were not a factor in this crash.
RCMP continue to investigate.
