Every GO station in the towns I cover: how many weekday trains go to Union, how long the ride takes, and what that means when you're choosing where to buy.
Checked October 21, 2026 against GO Transit's published timetables.
Each mark is one weekday train toward Union Station. The number beside each station is the daily total. The gaps matter as much as the count.
Trains only; GO buses are not shown. Barrie line: schedule effective September 5 and 8, 2026. Richmond Hill line: effective April 25, 2026. Stouffville line: effective October 26, 2026. Schedules change, so check gotransit.com before relying on a trip.

Ride time is scheduled departure to Union arrival on weekday trains. Parking is the total of the lots GO Transit lists on each station page, checked October 21, 2026.
YRT is free when you transfer to or from GO and pay with PRESTO, a credit or debit card, or show a valid GO fare. You get three hours from your GO tap, or two hours from your YRT tap. Many YRT stops serving GO stations are on the street, not in the station.

Lot sizes range from 160 spaces at Allandale Waterfront to 2,004 at Richmond Hill GO. The GO station pages I checked list free customer parking, with reserved and carpool spaces at many stations. Drive times vary too much by hour to quote, so test your route at the time you'd travel.

A fixed downtown 9-to-5 works from any line. Late meetings, shift work or flexible hours point to Aurora and south on the Barrie line, or Mount Joy and south on the Stouffville line.
Aurora GO has close to twice Newmarket GO's weekday trains, and Mount Joy has twice Stouffville's. A home between two stations can use the better one.
Two or three office days a week makes the rush-hour schedule matter more than the daily total.
More frequent service is planned, but without dates. If a commute only works once service improves, treat that as a bonus, not the reason to buy.
Metrolinx plans more frequent two-way, all-day service, seven days a week. No date or frequency has been published. Metrolinx
A second track is under construction up to Aurora GO as part of the Barrie line expansion. No completion date has been published.
