Seven people were taken to hospital, including five younger than 18, after a tractor-trailer and van collided on Highway 15.

Ontario Provincial Police said the crash happened at about 12:10 p.m. Saturday on the highway just north of Smiths Falls.

Lanark County paramedics said each person was in stable condition when they were taken to hospital and their injuries were considered serious, but not life threatening.

Police had earlier reported four children and two adults were in the van. No other details were released.

The road was closed and detours were put in place.
