Construction continues on One Bloor West's distinctive crown. Designed by Foster + Partners and Core Architects, and being completed by the developer Tridel, the 85-storey ‘supertall’ at Yonge and Bloor streets in Toronto’s Yorkville neighbourhood has seen enclosure progress since UrbanToronto’s July, 2026 update.
This month, the view southwest across Yonge and Bloor streets shows largely continuous curtain wall glazing across the north and east elevations, framed by anodized aluminum-clad megacolumns and six-storey diagonal hangers. Recessed mechanical sections punctuate the stacked residential volumes. At the base, tall glazed bays and broad cladding panels enclose commercial levels planned for retail and hotel uses. Red Tridel branding spans the street-level hoarding and lower-floor glazing, with a narrow strip of white weatherproofing exposed beside the ground-floor enclosure to the right.
The exterior appears substantially enclosed, including the uppermost six-storey residential volume, which remained partially open in July, while the south-facing strip behind the crane mast remains to be glazed: plywood barriers close slab-edge openings to approximately the 65th floor, with exposed concrete slabs and temporary guardrails follow through the highest residential levels. Steel crane ties bridge the mast and tower at intervals along this strip. White weatherproofing remains exposed beside the black louvres of the upper mechanical section, and rooftop steel subframes await exterior panels.
A close-up view of the first two-storey mechanical section at floors 17 and 18 highlights deep horizontal louvres that screen equipment behind roofs edged with glass balustrades. Anodized aluminum cladding features regularly spaced panel joints and finished soffits beneath the projecting residential floors. Triangulated crane ties cross the foreground, anchored through the unfinished strip, while green weatherproofing and exposed concrete mark incomplete enclosure work served by scaffolding and temporary guardrails.
Across the west and north elevations, the long west-side Rail Climbing System (RCS) truss and remaining north-side climbing units have been dismantled, clearing the crown of the facade installation system. Metal framing is visible between the megacolumns where penthouse suites will get top-floor interior space beside corner terraces.
Finally, a recent drone view at sunset reveals completed panels covering the Tuned Mass Damper chamber’s east-facing wall. Below, another look at where the four penthouse top level interior lounge space is being framed-in, each to have a corner terrace.
Standing 308.6m tall, One Bloor West was to contain 416 residential units before Tridel’s interior reconfiguration; a revised total and an operator for the planned 139-room hotel on the lower levels have yet to be announced.
