Just over three years ago, a surface parking lot southeast of Union Station began its transformation into the first of two towers, part of the most significant office development built in Downtown Toronto since the 1990s. The 49-storey south tower of Hines and Ivanhoé Cambridge's CIBC SQUARE office complex—designed by UK-based WilkinsonEyre Architects in collaboration with Adamson Associates—now stands at its full height of 237.7 metres as cladding installation bring the tower closer to its final form.

Construction of the project has been impacted by the COVID-19 pandemic, with the Province of Ontario announcing a construction shutdown that included office towers, halting tenant interior and amenity work until restrictions were lifted late in May. The continued presence of construction workers in the weeks between can be attributed to the project's GO Transit bus garage, housed in the podium levels. This component was exempted from the shutdown with transit construction having been deemed an essential service.

While many restrictions have been lifted as the pandemic loosens its grip, work has been scaled back to keep crews safe, with approximately 60% of the planned workforce operating on site to maintain social distancing. Other measures include limiting the number of workers allowed to ride hoists together, changes in work sequencing, and thermal imaging cameras to check workers' temperatures.

Within the tower, work is ramping up on the installation of drywall, mechanical, and electrical components, as well as the elevators. Up in the mechanical penthouse area, fireproofing and metal siding were recently installed behind the curtainwall glass crown. Other mechanical components now in place at the top of the tower include the primary roof plant air handling units, boilers, and pumps.

Along the tower exterior, glazing installation is covering up the final sections of the south and west facades, which were respectively occupied by tower crane mounting brackets and exterior construction hoists.

An expansive green roof continues to be installed atop the podium, just one of the many elements wrapping up within the lower portion of the building. On the podium's frontage on Lake Shore Boulevard, installation has begun for signage related to the GO Bus Terminal. The 10,000 m², bi-level transit facility turned a corner back in June, when the first GO buses entered the garage, and testing within the facility continues. Once complete, the new terminal will free up the site of the existing terminal to the north of the rail corridor, where the second phase of the office complex will soon be built.
