Two women have been rushed to hospital after a multi-vehicle collision in the city's downtown core.

The accident occurred near Dundas and Bathurst streets shortly after 11:30 a.m. Const. Clint Sitbbe said a taxicab was attempting to make a u-turn when it was struck.

Two females in the cab were found unconscious at the scene and were taken to a trauma centre while a third male victim was taken to hospital with non-life-threatening injuries. One of the women is in life-threatening condition while the other is in serious condition, Stibbe said.

All three injured people were inside the cab when it was struck, Stibbe said.

The Toronto Police Service's traffic services unit is investigating.

The area was closed to traffic for a few hours.
