BURLINGTON, ON

The hot weather has a significant effect on the GO rail network.

The  potential impacts to GO Train service resulting from the hot weather and heat patrols taking place across the GO rail network.

A heat warning from Environment Canada is in effect today for our service area. During prolonged periods of high heat, we are required to run trains at slower speeds. To ensure the safety of our customers and crew, slow orders are issued along the network.

 As a result, some trips may be cancelled or delayed on your line today arriving 10 to 15 minutes later than originally scheduled at their destination.

Check our Service Updates page for real-time information on GO service.

Please stay well hydrated, drink plenty of water and bring enough for your entire trip as not all GO stations have food or beverage options available. Plan ahead and give yourself extra time for travel.

Heat-related delays can be frustrating for customers, however Metrolynx must take proactive measures to ensure the GO Transit network operates safely in all kinds of weather conditions.
