Ontario begins work on value-based Caledonia GO station
Construction of an infill GO station on the Barrie Line at Eglinton Avenue West, known as Caledonia GO, has finally begun more than a decade after initial plans for the project were released. Designed to connect to the soon-to-open Eglinton Line 5, Caledonia GO is one of two new infill stations planned on the Barrie Line in western Toronto. The goal is to better serve commuters by modernizing the city's long-standing local transit network into a regional rail system.

In a press release issued on October 10, the Province of Ontario announced that the Caledonia GO Station construction contract was awarded to Grascan Construction Ltd. was awarded, more than five years after the first request for proposals (RFP) were published in July 2020. At that time, the station was scheduled to be completed in spring 2023. No reason was given as to why the RFP-to-construction process has taken more than half a decade, and neither Metrolinx nor the province announced a new expected opening date for the long-awaited station.

The shift is far from the first to impact the relatively modest station planned for the Keelesdale neighborhood, an area that has long been without mass transit despite being served by two high-capacity commuter rail lines. Initial plans for the Caledonia GO station were published in 2013 in conjunction with the start of major works on the Eglinton Line 5. The following illustration shows plans for a bus station and the construction of an additional track within the rail corridor to allow expanded round-trip services.

Three years later, a new series of renderings were released showing minor changes to the station layout, bringing the architectural design in line with that of the Eglinton Line 5 stations. The most significant change in this second version of the Caledonia GO station was the relocation of the bus terminal serving local TTC routes. The 2013 plan called for the terminal to be located east of the Barrie GO corridor at the northwest corner of Eglinton Avenue West and Croham Road. The revised plan moved the terminal to the west side of the rail corridor, directly above the Eglinton Line 5 underground platforms, allowing for faster and more convenient transfers between LRT and bus lines.

Building on these updates, an environmental project report released in 2016 provided a closer look at the station's planned capacity and design. An aerial view shows a kiss-and-ride loop at the site of the former bus station, as well as an additional entrance north of the Westside Mall on Bowie Avenue, further improving the station's local accessibility.

At platform level, the renderings showed a total of three tracks running through the station, served by a central platform and a single side platform. Such an expansion of rail capacity on the Barrie GO line, which for decades was largely single-track throughout the City of Toronto, would have enabled a revolutionary expansion of service, coupled with upgrades along the rest of the rail corridor, such as the recently completed Davenport Diamond track separation.

The Barrie GO line is currently served by a typical commuter rail pattern, with an overabundance of one-way trains in the morning and then reversing during the evening peak hours, with very modest bi-directional service on the remainder of the weekdays, with frequencies dropping even more sharply on weekends. Metrolinx's Regional Express Rail (RER) plan would have included a dramatic increase in train frequencies on a fully electrified Barrie line. With trains scheduled to run all day every 30 minutes in both directions between Toronto and Barrie, with frequencies up to every 15 minutes between Bradford and Toronto, and retaining existing express trains, the Barrie line had the potential to act as a major north-south rapid transit axis for the Greater Toronto Area.

The prospect of such a transformative expansion of rail service and frequency within the decade was dashed after years of inactivity on the project in the late 2010s and the eventual release of revised station designs in 2023. The new renderings of the Caledonia GO station were released through planning documents filed with the City of Toronto and demonstrated extensive value engineering. Long-standing plans to expand the station corridor to three tracks have been scrapped, as have the three platforms that would have been required to support the frequent round-trip service and express trains that Metrolinx has long promised to Barrie Line commuters.
Instead, the two platforms that were intended to be part of an island platform were removed, along with the two new tracks that would have served them, leaving only a single side platform and track in the new design. The right of way for a future second track and platform has been preserved within the station footprint and is shown as grass in the illustration below. However, as this first, simple version of the Caledonia GO station will take over a decade to build, it is impossible to predict when the second track and platform will be made available for public transport.

While true regional express rail service along an electrified corridor is decades away, if built at all, the mobility benefits of the Caledonia GO station under construction will still be significant. Currently, a public transit ride from Eglinton Avenue West and Caledonia Road to Union Station takes 45 minutes and requires a transfer at Eglinton West (soon to be renamed Cedarvale) station. Once Eglinton Route 5 opens, this journey will be shortened to approximately 30 minutes, with reliability improving thanks to the replacement of the bus service on Eglinton Avenue with grade-separated LRT.

With the final opening of Caledonia GO, travel times to Union Station will drop to just 15 minutes, with the journey consisting entirely of a single-seater ride on high-capacity GO Transit trains, allowing riders to enjoy views of the bustling West End neighborhoods and the impressive downtown skyline. This expansion of access to the core's employment and cultural centers would be a welcome improvement for any community and will particularly benefit residents of Keelesdale, a neighborhood that has long suffered from disinvestment.
