Common questions

How do I see the Union Station GO departure board on my phone?

Open the Union tab in OnTime GO. It lists every upcoming GO train leaving Union Station, the same as the big board in the station, with the platform, the number of coaches and whether the train is showing Proceed or Wait. It's free.

What do Proceed and Wait mean on the Union board?

Wait means the train's platform isn't open for boarding yet, so stay in the concourse. Proceed means you can head down to the platform shown and board.

Can I find out my platform at Union before it's announced?

With OnTime GO Premium you can see the scheduled platform before the board announces it, so you can start walking early. Scheduled platforms can still change, so follow the trip to get a notification if it moves.

Can I see only my line's trains?

Yes. Filter the Union tab to your line and the other trains drop away. Tap any train to see all of its stops and its expected arrival times.

Which GO lines leave from Union Station?

All seven GO train lines start at Union: Lakeshore West, Lakeshore East, Milton, Kitchener, Barrie, Richmond Hill and Stouffville.
