One month shy of three years since a ground breaking marked the start of work on the new CIBC SQUARE office complex in Downtown Toronto, the south tower has reached its final height just across Bay Street from the Scotiabank Arena. The first of two WilkinsonEyre-designed towers from developers Hines and Ivanhoé Cambridge now stands 49 storeys tall at a final height of 238 metres, following the installation of the uppermost section of structural steel for the tower's crown this week.

Construction surpassed significant milestones at the start of the year, when the tower's concrete elevator core topped out, and a ceremonial last steel beam was hoisted into place. With the core topped out, steel work for the uppermost office levels progressed into February, when the final office floor's steel structure was put into place. In the months since, which have included major construction slowdowns due to the COVID-19 pandemic, the tower's two-tiered steel crown has gradually materialized above.

The lower south crown topped out last month, while the final height was reached this week when the uppermost sections of the upper north crown's steel were installed. The south crown will surround a green roof, while the north crown wraps around a mechanical penthouse level as well as a building maintenance unit, with a height equivalent to five storeys.

Cladding installation has also made substantial progress in the last few months, now in place on all but the top three office floors and crowns. The distinctive diamond-patterned curtainwall glazing has become a standout feature in various views of the Downtown skyline, coming alive in the morning and evening hours as its facets reflect varying levels of light and colour.

Another milestone on the building's exterior was spotted late last month, when exterior accent lighting was first tested on the tower facades. A diamond grid of metal fins follow the glazing's diamond pattern, with spotlights affixed at the apexes that will ensure that the exterior expression remains just as identifiable on the skyline after dark.

The building's podium will be home to a newly indoor Union GO bus terminal, set to replace the open-air terminal that exists just north of the abutting rail corridor. Views into the bus terminal's Lake Shore Boulevard entrance show that interior finishes, lighting, and signage have been installed. Its opening is targeted for later this year, before the office tower above is occupied.

Once the new terminal opens, the existing terminal to the north is set to close and be demolished to free up space for the complex's 50-storey. 241-metre second phase.
