Toronto’s SkyTower at Pinnacle One Yonge, may climb even higher as Pinnacle International seeks approval to add another floor. Designed by Hariri Pontarini Architects, the supertall is already under construction and will be the first building in Canada to surpass 100 floors, and is currently approved at 105 floors at 345.5 meters

The newly submitted Minor Variance application proposes increasing floor heights between Levels 89 and 104 from 2.95 meters to 3.25 meters, allowing for 10-foot (3-meter) ceilings in the upper residential suites. Additionally, the lower level of the three-story mechanical penthouse would now house a 354 square meter residents' observation lounge, and two Level 105 penthouse suites would gain 160 square meters of pop-up second floors, reclassifying this previously programmed mechanical space as habitable space. This effectively would add a 106th floor, bringing the building’s total habitable height to 351.9 meters

The application also seeks approval for an emergency generator atop the mechanical penthouse. Staying within the existing 7.2 meter rooftop projection allowance, the generator would provide backup power for elevators and corridor lighting during outages.

Located at Yonge Street and Queens Quay East, construction of the supertall is well underway, with SkyTower rising beside The Prestige, and having completed the 65-floor first phase of the development. The building has had a history of height changes throughout the process with the high-rise initially approved at 95 floors, and later increased to 105 floors at 344.9 meters in 2023. It was further adjusted to 345.5 meters in 2024 after modifications to its mechanical penthouse.

Despite these changes, the building's overall design remains unchanged. The podium, setbacks, floor plate sizes, Gross Floor Area, unit count, and parking requirements will stay as previously approved, with the first 64 floors already formed. If the new variance application is approved, SkyTower will not only become Canada’s first 100+ story skyscraper but also reach new heights in residential luxury and functionality.
