Nine months after UrbanToronto documented Pinnacle International‘s SkyTower both crossing the 300m ‘supertall’ threshold and hitting the 100-storey mark in November 2025, cladding around the mechanical penthouse has left the tower with a short glass parapet around its perimeter. The tower terminates without the full-height crown enclosure designed by Hariri Pontarini Architects and depicted in earlier renderings, leaving much of the bare concrete structure and Building Maintenance Unit (BMU) exposed at the summit. Canada’s tallest building rises 106 storeys as the second phase of the Pinnacle One Yonge mixed-use community at Yonge Street and Lake Shore Boulevard on Toronto’s downtown waterfront.
Earlier this month, a drone view shows the curtain wall and white vertical fins largely complete at the uppermost levels, except along the east elevation where the construction hoist is attached. The crane stands on the west side, while the roof hosts the BMU, the Tuned Mass Damper chamber, other mechanical equipment, and staged materials. At this point, fencing still lined the roofline, leaving the upper concrete volume visible around the elevator overrun and BMU.

Across the upper roof, the final unitized curtain wall sections stand in timber transport racks behind temporary perimeter guardrails. The prefabricated assemblies pair dark-tinted glazing with black aluminum framing, continuing the broad glazed bays, projecting white fins, and faceted corner panels below. Blue weatherproofing remains exposed along portions of the slab edge.

A close-up captures final detailing beside the hoist, where blue-tinted glass guards line the rooftop edge above the completed curtain wall. At right, a compact rooftop crane assists a crew member guiding a narrow white metal closure panel between the guard glazing and a projecting fin.

A few days later, the crane has begun to dismantle itself, with the shortened jib and climbing assembly lowered to roughly the roofline. Crew members stand atop the mechanical levels near the hoist, whose run interrupts the otherwise continuous envelope with exposed slab edges, concrete columns, temporary platforms, and localized openings.

The next day, the lattice jib was below the roofline. SkyTower’s twelve-sided envelope combines blue-grey reflective glazing, slender dark mullions, and white fins that rise along its chamfered elevations before angling inward with the taper. A recessed stack of balconies with glazed guards marks the southeast corner, while rooftop guards trace the upper edge below the concrete mechanical section.

Most recently, the slewing assembly and jib descend below the uppermost white horizontal accent bands, as the crane casts a shadow across the reflective glazing.

SkyTower stands 351.85m tall, containing 958 condominium suites above a podium with retail, amenities, and a 223-room Le Méridien hotel. A third Pinnacle One Yonge tower is proposed to rise 320.35m, adding another 95-storey ‘supertall’ to the waterfront development at some point in the future. Below, one of the earlier versions of the peak of the tower proposed a screen to elegantly hide all of the projections atop the building.
