The O-Train returned to normal service Sunday afternoon after it was shut down following the discovery of a body on the tracks.
Police said foul play is not suspected. They were concluding their investigation late Sunday afternoon.
Ottawa police had earlier closed the eastbound lanes of Somerset Street West between Breezehill Avenue and Preston Street.
Police tape had also been placed across the multi-use pathway running underneath the Somerset Street bridge.
Bus route 107 served transit users during the shutdown.
