Ontario has boosted GO train service by more than 70% so far, adding about 800 train trips each week throughout the GO network than were offered in 2013.
In the weeks ahead, the province plans to begin the design-build process for six new GO stations and six new city of Toronto SmartTrack stations.
Upgrades will also be made to more than 20 existing GO stations, officials said, including renovations to station buildings, new bus loops, digital signage and other improvements.
The province will also take steps to begin the procurement of new maintenance facilities, trains, tracks and additional infrastructure needed to increase service offerings.
Weekly trips across the entire GO rail network are predicted to rise from about 1,100 in 2013 to nearly 6,000 by 2025, officials said. More all-day, two-way, 15-minute electrified GO service is planned for commuters throughout the region.
