GORHAM TOWNSHIP, Ont. -- A child who was the subject of an Amber Alert in northern Ontario was found 30 kilometres from where he went missing on Monday as police continued to search for his mother.

Ontario Provincial Police said the eight-year-old boy, first reported missing from Gorham Township at 9 a.m. Monday, was located roughly three hours later at a Tim Hortons in Thunder Bay, Ont.

Sgt. Shelley Garr said the Amber Alert was issued because the child was believed to be in danger at the time. She offered no word on the boy's condition but said he has been taken into protective custody.

Garr said the child went missing in the company of his mother, who police are still trying to locate.

She said it was not known whether the woman is on foot or still driving the vehicle listed in the original alert.

"She's still out there and we're actively looking for her, " Garr said, adding there is no reason to believe the woman poses a risk to the public.
