Here's how Toronto's skyline could look in the decades to come

Toronto has undergone a period of profound vertical growth in the first quarter of the 21st century, but some of the biggest and boldest projects that will define the city's skyline of the future are still on their way to fruition.

A glut of office space amid soaring vacancy rates may have cast doubt on the future viability of some major proposals, though other commercial projects are pressing on through the doom and gloom reports. 

Meanwhile, while towering residential projects may have slowed compared to the boom years, many more are already well under construction, and others simply await reaching sales targets before shovels can hit the ground.

It's practically impossible to gauge exactly what Toronto's skyline will look like a decade or two down the road, but one new rendering attached to a major project in the pipeline offers a pretty good glimpse at what passengers on planes landing and taking off from Billy Bishop Airport may see out their windows in the not-too-distant future.

A recent resubmission for the long-discussed Union Park development includes one such rendering of Toronto's possible future skyline.

The enormous development from Oxford Properties was first proposed in 2019 and was reshaped in 2024, with some of the proposed office space swapped out in favour of added residential.

But Union Park is just one of many new developments rendered in this skyline view, joined by several other planned and under-construction towers that include some of the tallest buildings in Canada.

New developments, along with their planning or construction status, are named below, as seen from left to right in the rendering above.

• Concord Canada House (currently topped out and nearing completion as of 2025) 
• Union Park (proposed) 
• Forma (first tower under construction, rising above street level) 
• Union Centre (proposed) 
• The HUB (proposed)
• CIBC Square north tower (tallest office tower under construction in Canada, will top out in 2025)
• 191 Bay Street (proposed) 
• Pinnacle One Yonge (under construction, expected to become Canada's tallest building in 2025)
• Sugar Wharf Phase 2 (proposed)
