Four people were freed by firefighters following a two-vehicle collision that happened around 5:30 Sunday afternoon in the area of 10 Sideroad and 6th Line in Innisfil.
"A vehicle travelling westbound on the 6th Line failed to stop for a stop sign and collided with a vehicle travelling southbound on 10 Sideroad," police said in a news release on Monday. "The westbound vehicle then struck a utility pole, trapping the four occupants. A man and a woman, both aged 38, and two children, aged 5 and 8, all from Woodbridge, were freed by firefighters. The man and 8-year-old child were transported to a local hospital where they were treated and released. The woman and 5-year-old child were airlifted by Ornge to a Toronto trauma centre where they are being treated for non-life-threatening injuries. The sole occupant of the southbound vehicle, a 60-year-old woman from Bradford, was taken to a local hospital where she was treated and released."
Roads were closed for nine hours while officers completed a collision reconstruction and crews replaced the utility pole.
The investigation is ongoing.
