Police previously said he was last seen around 2:30 p.m., in the Tam O’Shanter-Sullivan neighbourhood, near Sheppard Avenue East and Birchmount Road.

Steven is described as 80 years old and standing five-foot-six with a slim build and short grey hair that is balding.

He was last seen wearing a navy blue button-down style dress shirt, a navy blue fleece vest, blue jeans, and grey running shoes with white soles.

Police are concerned for his safety as he’s now been missing overnight and was last known to be on foot.

‘Time is of the essence’

“Time is of the essence. All types of resources are being dedicated to finding Stephen, and there are concerns,” Const. Viktor Sarudi told CP24 on Monday afternoon.

“We’ve spoken with the family and Stephen has been diagnosed with Alzheimer’s also, just important for the public to know for when they approach him he might not fully understand what’s happening. So, we do ask for people’s compassion if they spot him, and then they call us and we’ll be there to help.”

Const. Viktor Sarudi, TPS, Feb. 16 Const. Viktor Sarudi, of Toronto Police Service, speaks with CP24 on Feb. 16.

The media officer said investigators don’t know if Steven is able to get around on the subway, but are urging people to keep an eye out for him in case he is on public transit.

“We’re asking people to be aware. Keep an eye out for him, and if they do see him, due to the urgency of not only his age but the weather and how long he’s been missing, it’s a 911 call to say that you spotted a person that the police are looking for,” Sarudi said.

“Keep an eye out on areas where someone might naturally go for warmth in this type of weather, whether that’s an open shed you might have or a car that was left unlocked, that someone might feel like they can find some sort of refuge in. That’s what we’re asking the public to do.”

Anyone with further information is asked to contact Toronto police at 416-808-4200 or Crime Stoppers anonymously.
