What type of work is happening:   

Metrolinx is transforming GO Transit to bring more frequent two-way, all-day service to the Barrie Line seven days a week, so you won't need a schedule because you know the next train will be coming soon. To support the future addition of a second track, key areas of the corridor along the Barrie Line are being expanded. In addition to corridor improvements, significant station upgrades at Maple, King City and Aurora GO stations are progressing.
