Police are investigating a fatal collision involving a pedestrian that happened around noon Thursday at a townhome complex in Kitchener.

A spokesperson with the Waterloo Regional Police Service said the crash involved a pickup truck being operated as a plow and salter near Ottawa Street South.

Police determined that a 45-year-old Kitchener woman was driving the truck, and clearing snow in a parking lot, when she struck a 74-year-old woman who was walking across the parking lot behind the vehicle.

One neighbour told CTV News Kitchener he was working from home, and noticed something was wrong when he came outside to see if he needed to move his car for the plows.

"I saw her lying on the parking lot face down," said Andrew Plata. "A few of my neighbours had surrounded her, see what they could do to help her. Shortly after that the paramedics showed up."

The incident left Plata shaken.

"Makes you think, you come outside and you're walking in the parking lot, you don't really know. You just really don't know."

Region of Waterloo Paramedics Services said they arrived to find the woman in cardiac arrest and were unable to resuscitate her.

She was pronounced dead at the scene.

Officials say they are still trying to notify next of kin.

The driver of the pickup truck was not hurt.

Police remained at the complex for most of the afternoon, but left around 4:30 p.m. after the pickup was taken away by a flatbed truck.
