Back in 1982, GO train service on the Stouffville Line started with humble runs. In fact, to begin, it was a single weekday service.

Fast forward to 2019, and you can see this decidedly less modest service hitting its stride.

Starting Nov. 2, hourly trains will run between Union Station and Mount Joy GO Station every Saturday, Sunday and holiday.

This expansion means Stouffville Line customers between Markham and Toronto now have all-day GO train service, seven days a week. The new trips are particularly good news for customers travelling to and from Milliken, Agincourt and Kennedy GO stations, which aren’t currently served by GO Transit on the weekend.

“Hop on board and come downtown for a Leafs or Raptors game, a meal with friends and family, or to catch the Santa Claus Parade,” said Metrolinx President and CEO Phil Verster. “The trains will offer customers a relaxing ride without fighting highway traffic; connecting people with what matters the most.”

Some morning and evening trains will also extend to Lincolnville GO, while GO buses will provide connections north of Mount Joy for the rest of the day.

With the introduction of these weekend trains, GO bus service on the Stouffville corridor will run every hour instead of every 30 minutes on weekends.

And remember those weeknight Stouffville trains that came back in September? The parallel bus service on Routes 70/71 (Stouffville) will also be reduced starting Nov. 2. Buses will continue to connect with trains at Mount Joy to serve all stops to Uxbridge, and three remaining weeknight bus trips will allow customers to travel from Union Station to Uxbridge.

November brings some other changes to GO bus service.

To ensure resources are being used when and where they’re needed most, Metrolinx is reducing and adjusting service on select GO bus routes starting Nov. 2:

• Some trips on GO bus Routes 30, 31 and 33 (Kitchener/Brampton/Toronto) have been removed or adjusted to account for the new train service added to the Kitchener line in September.
• GO bus Route 12 (Niagara Falls/Burlington) will begin serving the future site of Confederation GO (the new park and ride lot at QEW/Centennial Pkwy N), replacing the current stop at Barton St. E and Nash Rd. N. This will offer customers more parking and better highway access.
• With double-decker GO buses now serving Route 21 (Milton/Toronto), certain trips are being merged to make better use of resources. This means some stops currently served by different buses will now be served by the same bus, but at generally the same times.
• Weekend service on GO bus Route 52 (Hwy. 407 Terminal/Oshawa) will be reduced by six trips every Saturday and Sunday, due to low demand.
• Service on GO bus Route 66 (East Gwillimbury/Newmarket/North York) will be reduced by 14 trips every weekday due to low demand. Since taller double-decker buses will now operate on this route, the stop in the Newmarket Bus Terminal will move to just outside the building at Davis Dr. W and Eagle St. W.
• Peak service on GO bus Route 67 (Keswick/North York) will be reduced by one trip every weeknight due to low demand.
