This coming weekend (July 11 and 12) sees an annual rite of summer for Toronto – closure of the Gardiner Expressway for summer maintenance. And that’ll mean some changes for some GO Transit bus customers. 

Heavy traffic is expected on roads to and from Union Station Bus Terminal (USBT), and bus travellers are advised to allow extra time for trips. 

Metrolinx has planned ahead with service adjustments. Here is what you need to know about trips normally scheduled to arrive at or depart USBT between 9 a.m. and 9 p.m. on Saturday, July 10, and Sunday, July 11. 

Route 16 buses will not run. Customers can take Route 18 and connect to Lakeshore West trains running between Aldershot GO and Union Station. 

Trains will run every 30 minutes all day. PRESTO customers transferring from the bus to the train, should tap on and off on the bus, and tap on and off at the train station as usual. 

Route 21 and 31 buses will connect to Lakeshore West trains running between Port Credit GO and Union Station. 

Trains will run every 30 minutes all day. PRESTO customers transferring between bus and train service, should only tap on and off the bus. Do not tap on or off at the station for the train. At Port Credit GO, the fare between there and Union Station will be automatically applied when you tap on or off the bus. 

Route 65, 68 and 71 buses will run to and from Hwy 407 Bus Terminal, connecting with TTC subway service, providing Union Station access along Line 1. 

PRESTO customers transferring between a GO bus and the TTC should tap on and off the GO bus. You do not need to tap on or off the TTC. When entering the TTC, show your PRESTO card or GO ticket at the booth. At Hwy 407 Bus Terminal, the fare between there and Union Station will be automatically applied when you tap on or off the GO bus. 

Metrolinx will have extra staff in the stations to help customers get where they need to go.  

Outside these hours, GO bus service will run to and from USBT as usual. 

Online schedules will show the regular trip times and stops but you can visit the Schedules Changes page for more information.  

As always, you can sign up for On-The-GO alerts to receive timely, customized information about service changes and other GO news.
