In April 2015, the government of Ontario announced that as part of a broad GO Transit expansion project called [[GO Transit Regional Express Rail|Regional Express Rail]], service on the Barrie line would increase from 7 daily train trips to over 20 daily train trips by 2020.{{sfn|Kalinowski|2015}}{{efn|As of April 2015, there are seven daily southbound weekday morning trains on the Barrie line, and seven daily northbound weekday evening trains.}} The [[railway electrification system]] was planned to be completed by 2024 and feature two-way, all-day service every 15 minutes between  Union Station and Aurora GO.{{sfn|Kalinowski|2015}} However, on August 12, 2021, Metrolinx announced that, after electrification there would be 15-minute, two-way, all-day service beyond Aurora to Bradford, and 30-minute two-way, all-day service to Barrie South and Allandale Waterfront.<ref name="Metrolinx-2021-08-12">{{cite web |url=https://blog.metrolinx.com/2021/08/12/metrolinx-plans-to-bring-15-minute-two-way-all-day-go-service-further-north-on-the-barrie-line-to-bradford/ |title=Metrolinx plans to bring 15-minute, two-way, all-day GO service further north on the Barrie Line to Bradford |publisher=[[Metrolinx]] |date=August 12, 2021 |access-date=August 12, 2021 |archive-url=https://web.archive.org/web/20210813015350/https://blog.metrolinx.com/2021/08/12/metrolinx-plans-to-bring-15-minute-two-way-all-day-go-service-further-north-on-the-barrie-line-to-bradford/ | archive-date=August 13, 2021 }}</ref>

===Additional stations===
In the September 2015 planning document "New Station Analysis", an initial list of 22 potential GO station sites were identified. These were, from north to south, at Innisfil, Holland Yard, Mulock Drive, St John's Sideroad, Yonge Street, Bathurst Street at Side Road 15, Dufferin Street, Kirby Road, Keele Street at Teston Road, Langstaff Road, Highway 7, Steeles Avenue, Finch Avenue, Downsview Park, Wilson Avenue, Lawrence Avenue, Caledonia Road, Rogers Road, St Clair Avenue West, Davenport Road, Dupont Street, and Bloor Street.{{sfn|Woo|2015|p=19}}

Of these, most were rejected as unsuitable, either because they were too close to other stations,{{sfn|Woo|2015|p=17}} or for failing to meet other criteria, such as connections to other services, proximity to urban growth centres,{{sfn|Woo|2015|p=22}} construction viability, urban density, or necessary infrastructure.{{sfn|Metrolinx|2016|p=11–12}}  Others were rejected because they were considered for other lines on the network.{{sfn|Woo|2015|p=12}} Four sites were considered for either the Barrie line or the [[Kitchener line]].{{sfn|Metrolinx|2016|p=13}} The sites at Highway 7 in Vaughan and at St Clair Avenue West were not included as part of the 10-year RER expansion, but are part of a future expansion program.{{sfn|Metrolinx|2016|p=21-23}} The candidate location Bathurst Street at Side Road 15 was deferred for future consideration.{{sfn|Metrolinx|2016|p=26}}

Stations have been approved in Vaughan for the Kirby Road site (serving the community of Hope), at Mulock Drive in Newmarket, and in Innisfil.{{sfn|Metrolinx|2016}} Under the Regional Express Rail initiative, new stations are planned in Toronto: [[Bloor–Lansdowne GO Station]] at [[Bloor Street]] West (near [[Lansdowne Avenue]] and {{stl|TTC|Lansdowne}} subway station) and [[Spadina–Front GO Station]] at [[Spadina Avenue]] near [[Front Street (Toronto)|Front Street]] (with access to the [[CityPlace, Toronto|CityPlace]] neighbourhood and [[510 Spadina]] streetcars).{{sfn|Metrolinx|2016|p=18}}{{sfn|Spurr|2016}}

====Caledonia station====
{{Main|Caledonia station}}
The design for Caledonia station on [[Line 5 Eglinton]] includes provisions for a connection to the Barrie line, including a pedestrian bridge above the Barrie line and provisions for elevator access to future GO platforms.{{sfn|Metrolinx|2013}} Metrolinx announced that an environmental assessment for the station would begin in the summer of 2015.{{sfn|Metrolinx|2015}}

====Innisfil GO Station====
{{Main|Innisfil GO Station}}
Metrolinx is considering a station in [[Innisfil]] for a future expansion, to be located at approximately mile marker 52 (kilometre 83.7). They analyzed two sites just east of Sideroad 20: 5th Line near Lefroy's Lormel subdivision and 6th Line near the future Sleeping Lion development in south Alcona.{{sfn|Vanderlinde|2016}} Innisfil town council stated its preference for the 6th Line location, which was ultimately chosen by Metrolinx,{{sfn|Metrolinx|2018}} and approved use of $2 million to acquire land and $2.6 million to partially fund the station's construction.{{sfn|CTV News|2016}}

====Concord GO Station====
To provide an interchange with [[Viva Rapid Transit|Viva]], a [[bus rapid transit]] service in [[Regional Municipality of York|York Region]], a new station was proposed at [[Ontario Highway 7|Highway 7]]. The site was called Concord station, after the [[Concord, Ontario|Concord]] neighborhood in which it would be located.{{sfn|City of Vaughan|2013|p=15}} The city of [[Vaughan]] has integrated the station into its design plans for a mixed use development near the intersection of [[Ontario Highway 407|Highway 407]] and the rail corridor. Both the municipal government of Vaughan and the regional government of York have identified this location as a potential site for the station, which requires GO Transit to perform an environmental assessment.{{sfn|City of Vaughan|2013|p=16}} In January 2013, Vaughan municipal clerk sent a [[Vaughan City Council]] resolution to [[York Regional Council]] requesting Metrolinx consideration for four priority projects, among them all-day two-way service on the Barrie line, creation of the Concord GO Station, and creation of a Kirby Road GO Station.{{sfn|Kelly|2013|p=2}} The station would be located near the old CN Concord Station (located north of Highway 7 on east side of tracks on the current Barrie line) that dated back to the [[Northern Railway of Canada]] Thornhill Station c. 1853 and demolished in 1978. In 2023, a business case for the station was released.<ref>{{cite web |title=Business case for proposed Hwy 7/Concord GO station released |url=https://www.metrolinx.com/en/news/business-case-for-proposed-hwy-7-concord-go-station-released |website=Metrolinx |access-date=May 6, 2023 |date=May 4, 2023}}</ref>
