Police say Suzanne Pac, 58, was struck around 1:30 a.m. by a car travelling southbound on Sherbourne Street near Dundas Street East.

Pac, who was just steps from the building where she lived, was pronounced dead shortly after being taken to a trauma centre.

Const. Clint Stibbe said she was hit in the roadway and the driver kept going.

"There's no way that this person did not know that they struck an individual," he said. "As a result, they have to understand they need to get a lawyer."

Police are seeking a four-door, graphite lustre metallic Acura TL (2012-2014) with front-end damage.

They have gathered debris from the vehicle that was involved and have some video evidence from the area, Stibbe said.

A water main break sent water streaming down the road and police are looking into whether that played a role.

Jordan Byrne, who lives in the same building as the mother of two, said he witnessed the collision between the car and Pac, who was walking in the street.

He said he tried to read the licence plate as the car drove away but wasn't able to.
