Multiple people ended up in hospital after a semi-tractor trailer struck a tow truck while it was pulling another vehicle out of the ditch along an icy Winnipeg highway shortly after noon.

RCMP received a call about the seven-vehicle crash on the city's south Perimeter Highway near St. Anne's Road at 1:10 p.m. on Sunday.

Four other vehicles were reported to be involved in a chain reaction of collisions as a result of the initial crash between a semi, a tow truck and the vehicle it was hauling, an RCMP spokesperson confirmed in an email.

Cpl. Julie Courchaine was uncertain how many people were taken to hospital and the extent of their injuries.

Courchaine said roads were identified as icy at the time of the collision.

All lanes are now open to the public. The Perimeter Highway's westbound lanes reopened around 5 p.m. after being closed for the afternoon due to the collision.

Officers are expected to stay on scene for a while.
