The regional supervising coroner for northwestern Ontario says officials are "worried about the health and well being of the mother" after the body of an infant was discovered Monday afternoon in Thunder Bay. 

In an email to CBC News, Dr. Michael Wilson said officials "encourage [the mother] to seek help as necessary," adding that the woman is welcome to contact his office directly with any information. 

Thunder Bay police said a post mortem examination on the infant's body will be performed tomorrow in Toronto.

The body was found by a passerby just after 1:30 p.m. on Monday in a wooded area near a path along the south side of the Neebing River in Thunder Bay.

The walkway between Legion Track Drive and Tarbutt Street remained cordoned off on Tuesday morning. 

Wilson said the case is under active investigation and officials are hoping to identify the baby and the mother. 

Thunder Bay Police spokesperson Chris Adams told CBC News no further information was being released at this stage of the investigation, including the baby's gender. 

"At this point holding back information sometimes helps us filter between fact and fiction when information comes forward," he said. 

The Thunder Bay Police Service's Criminal Investigations Branch has set up a tip line. Anyone with information is asked to call 807-684-1055. Police say they can also call Crime Stoppers at 1-800-222-TIPS or go to www.tipsubmit.com.
