"By the first quarter of February 2021, all interior works including the Bay Concourse, Bay Retail, and the Front Street Promenade were completed and turned over to the City for the sale of the Bay Concourse to Metrolinx and turnover of retail spaces for interior fit-out to Osmington to open to the public as soon as possible. This phased turnover will lead to new areas of the station opening up as they are ready, which will contribute to improved pedestrian flow through the station and enjoyment of the commercial and retail amenities. Metrolinx and Osmington will ultimately determine exactly when these areas of the station open to the public. Based on typical construction schedules it is anticipated that Osmington will open the remaining retail units on a rolling basis throughout 2022 and that Metrolinx is expected to open the Bay Concourse to be available for public usage in late second quarter of 2021."

Update on the installation of a new security barrier system outside Union Station
Although separate from the U.S.R.P., work is underway to develop and implement a new barrier system around Union Station. The impacted areas house significant and complex sub-surface infrastructure and systems belonging to multiple entities. To ensure that the new barrier system integrates properly with existing infrastructure, the City is coordinating with relevant stakeholders to finalize the design and issue a construction tender by the end of the third quarter of 2021. The existing jersey barriers will remain in place until the new barrier system is complete, which is expected to occur by the end of 2022.
