The two were found in the Fort York Boulevard-Lake Shore Avenue West area of Toronto at an address on Bruyeres Mews.
Kaitlynn Dunn, spokesperson with the Greater Sudbury Police Service, said the 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.
She said officers also checked with the Ontario Northland and Greyhound "because we always check those in case the person is looking to flee town."
Dunn said that around 3 a.m. Tuesday, an Ontario Northland employee confirmed to police that the pair had been seen boarding a 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 his mother, Dunn said. The alert was lifted around 7:55 a.m.

Dunn said the mother and child are in good health, and Sudbury police will investigate to determine "the intent of taking the child" and whether any charges will be laid.
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.
"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."
Once again our Communications Centre has been receiving a number of calls from citizens using it as a platform to complain about being awaken by the Amber Alert.<br>REMINDER:<br>9-1-1 is for EMERGENCIES ONLY. Please help us to keep our phone lines free for real emergencies. Thanks^adc
Dunn said calls 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."
Toronto police say a three-year-old boy and a woman who were at the centre of an Amber Alert issued on Tuesday have been found safe.
The alert was requested early Tuesday morning by Sudbury police officers who said they believed the toddler had been abducted by a 25-year-old woman.

Amber Alert texts once again have people complaining
The Amber Alert once again prompted police services in the GTA to remind people not tie up police resources by calling 911 to complain.
"Once again our communications centre has been receiving calls from citizens using it as a platform to complain about being awaken by the Amber Alert," the tweet read. "Please help us to keep our phone lines free for real emergencies."

Peel Regional Police also took to social media to remind the public about appropriate emergency calls.
"The service is used for a reason and a purpose. Dont call to complain, call if you see the subjects in the alert," Peel police tweeted.
Insp. John Valtonen, of the Greater Sudbury Police Service, said locating a missing child is more important than the inconvenience caused by an Amber Alert.
"To put it bluntly, the discomfort or the inconvenience that an Amber Alert would have for an individual certainly does not trump the safety of a child, full stop," he said.
“There’s only so many call takers responding to 911 calls and if somebody is calling 911 to complain about an Amber Alert call, somebody who’s having a heart attack may not be able to get right through,” said Virgin.
