Hamilton police said Matanal Lawton-Sibony, 15, who had gone missing last night was found on Tuesday morning.
In a Twitter post, Hamilton Police said they were "no longer concerned for his safety," and thanked everyone who had shared information about his disappearance.
Police had asked the public to keep an eye out for Lawton-Sibony, who went missing after an argument at his mother's house. He was later found at his dad's.
Police said the biggest concern was that the teen had left home, in Hamilton's west end near Ewen Road, wearing just a t-shirt on a cold night.
The teen has Asperger's Syndrome and is new to the area, coming from Israel 6 months ago.
