The Ontario Line is a planned rapid transit line that will connect Science Centre station (on Line 5 Eglinton) to Exhibition GO station (on the Lakeshore West GO line). A connection to Line 2 is planned at Pape station. The new platform and tracks will be constructed underneath and perpendicular to the existing Line 2 platforms, slightly to the east of Pape Avenue, to avoid traffic and utility disruptions during construction. As of December 2020, the expected completion date of the Ontario Line is 2030.
