Boy, 3, found safe in Toronto after Amber Alert issued in Sudbury, Ont.

A call to a tip line from a woman being sought in an Amber Alert helped in locating her and her three-year-old son safe in Toronto early Tuesday, say Sudbury, Ont., police, who issued the alert.

The two were foundin the Fort York Boulevard-Lake Shore Avenue West area of Toronto at an address on Bruyeres Mews.

Kaitlynn Dunn, spokesperson withthe Greater Sudbury Police Service, saidthe mother and son were dropped off at the Rainbow Centre Mall on Monday around noon ET. The boy was supposed to be brought back to his guardian, his grandmother.

The grandmother phoned police when the child wasn't returned to her.

"We began checking places that his mother is known to visit," Dunnsaid.

She saidofficers also checked with the Ontario Northland and Greyhound "because we always check those in case the person is looking to flee town."

Dunn said thataround 3a.m. Tuesday, an Ontario Northland employee confirmed to police that the pair had been seenboardinga bus in Sudbury en route to Toronto on Monday afternoon.

The alert was issued around 5 a.m. and the boy was reported safe around 7:30 a.m. after a call was placed to the police tip line by hismother, Dunn said. The alert was lifted around 7:55 a.m.

Dunn said the mother and childare in good health, and Sudbury police will investigate to determine "the intent of taking the child" and whether any charges will be laid.

Get an alert? Don't dial 911 to complain, police say

The alert went out across Ontario just before 5 a.m. Both police in Sudbury and Toronto confirm calls were made from the public about being woken up by the alert itself.

"A child's safety does trump somebody's sleep," Dunn said.

"We felt it was necessary to put out the Amber Alert in order to ensure he was safely found and it did just that: he was safely found."

Dunn saidcalls to 911 should only be placed in certain circumstances: "911 is reserved for emergency matters. Your opinion or being upset regarding an Amber Alert is not an emergency matter."

• The child is under 18 years old.
