[8] The old TTC bus loop located at the northwest corner of Renforth and Eglinton was decommissioned and incorporated into the site.

In April 2022, construction of the "Crosstown West Extension" began along Eglinton Avenue to the east in Toronto from Mount Dennis station.

In December 2021, parts of the tunnel boring machines (TBMs) that would bore the twin tunnels 6.3 kilometres (3.9 mi) eastwards along Eglinton from a launch shaft at the future station site arrived and were assembled prior to excavation.

[10] The first TBM, dubbed Renny (the name being a reference to Renforth Drive), began tunnelling in April 2022 but the second, named Rexy, started later, by early August, as the launch area was only wide enough to launch one TBM at a time.

[13] As an interim project, land was preserved for future dedicated bus lanes to the airport.
