Two tracks have reopened on the Lakeshore West GO Transit line and regular service resumed after a person was struck near the Port Credit station Tuesday afternoon.

GO Transit says the person, who was struck on the westbound line, has died. Peel Paramedics could not confirm the age or gender of the victim.

Peel Regional Police were at the scene and members of the Major Collision unit were called in to investigate.

Metrolinx spokesperson Anne Marie Aikins said delays that result from a pedestrian having been struck typically last a couple of hours.

"It's going to seriously impact Lakeshore service, perhaps going into rush hour," Aikins told CBC News. By 4:23 p.m., GO announced that two tracks had reopened at Port Credit, allowing regular service to resume.

However, delays persist through the evening.

During the service disruption, travellers were able to take a train from Union Station to Long Branch, where they could board a bus to continue on to Clarkson before carrying on again by train.
