Work started in 2012 with the demolition of the former York Theatre and a pair of adjacent low-rise commercial buildings, and in the years since the 33 and 36-storey, Kirkor Architects-designed towers have been structurally completed. That structural work culminated with the removal of the east tower’s crane this past March, and over this past weekend with the removal of the crane atop the taller west tower.

The operation was carried out using a massive
All Canada Crane Rental Corp mobile crane, which required the temporary closure of Eglinton between Yonge and Redpath, resulting in the detouring of both eastbound and westbound traffic for the duration of the crane removal.

A hydraulic telescoping arm allows the mobile crane to stretch above the condominium tower’s roofline, where individual segments of the tower crane are fixed to the temporary rig. The segments are then disconnected from the tower crane, and carefully lowered down to street level to be loaded onto a waiting flatbed truck.

While the process may seem relatively straightforward on paper, plenty of precise calculations and complex engineering is required to keep the mobile rig stable while lowering such massive crane components. This is evidenced by the stack of counterweights at the base of the rig, shown in the image below with red triangular markings.

The crane removal process wrapped up on Sunday morning, when the temporary rig was loaded onto a flatbed truck and transported off to its next job site.
