A police investigation brought O-Train service to a halt Sunday. 

O-Train service was suspended for hours on Sunday after a body was discovered on the tracks near Bayview Station. 

The eastbound lanes of Somerset Street West were closed between Breezehill and Preston for hours as part of a police investigation. Caution tape also closed off part of the multi-use pathway near the Somerset Street pedestrian bridge.

Police did not release details about what happened but did say the incident was deemed to be "not suspicious."
