A woman is in critical condition after apparently pushing aside a stroller just moments before her group was hit by a truck.

Ottawa paramedics said they were called to the intersection of Centrepointe Drive and Tallwood Drive in west Ottawa around 9:24 a.m. Wednesday.

They said a 69-year-old woman suffered life-threatening head injuries, along with potential spinal and internal injuries.

A 68-year-old man was taken to hospital in stable condition with arm and abdomen injuries, while the 16-month-old girl in the stroller was taken to CHEO with minor scrapes and bruises.

Ottawa paramedic J.P. Trottier said there are reports the woman may have reacted quickly to save the child.

"There are some witnesses that told paramedics it appears as if the stroller may have been pushed aside prior to the impact," he said.

Other witnesses said the group was hit by the truck as it rounded a corner, a sign of busier traffic on Centrepointe Drive because of congestion on Woodroffe Avenue.

"It makes me really ill to think that there's people crossing the street with strollers and people are still turning left on top of them," said Amy Oke, who lives nearby.

"Mostly in the city when the speed limit's 40 (kilometres an hour) no one really goes 40, they go about 60 or 70."

Ottawa police are investigating the crash and closed nearby roads for a few hours.
