Rendering of M City, an eight-tower development rising up on 15 acres of land in downtown Mississauga. M3, one of the towers, will be the tallest skyscraper in Canada outside of Toronto when it’s completed.

Mississauga is one step closer to becoming home to the tallest completed skyscraper in Canada outside of Toronto.

At 258 metres in height (83 storeys), the third highrise in what will eventually be an eight-tower mixed-use development at Burnhamthorpe Road West and Confederation Parkway in the city’s downtown core recently hit a significant milestone, City of Mississauga officials said on Monday.

City officials offered a nod to the project’s developer for “topping off” construction on “Mississauga’s tallest tower,” known simply as M3.

M3, the tallest of the eight towers that will comprise the  multibillion-dollar condo community known as M City, “marks a milestone in suburban highrise development and sets a new benchmark for vertical living beyond Toronto’s core,” a spokesperson for the engineering firm behind the skyscraper said in an email to INsauga.com.

Congrats to M City Condos by Rogers Real Estate Development Ltd. and Urban Capital on recently “topping off” construction on Mississauga’s tallest tower. Building in the sky is complicated – especially when it’s an 83-storey tower.

The structure, measuring nearly 850 feet in height and to be the tallest in Canada outside of Toronto, is “a case study in how highrise construction is now possible in non-downtown regional centres,” the spokesperson for RJC Engineers added.

“Mississauga is shifting from a commuter suburb into a dynamic urban centre, driven by rapid zoning changes and housing demand. M3 embodies that evolution. It serves as a real-time example of how structural engineering is enabling this shift, shaping not only skylines but the future of suburban city-building in the GTA.”

Two award-winning 62-storey condo towers dubbed M1 and M2 have already been completed and are occupied as part of the 15-acre development that will be completely finished some years down the road.

M4, the next in the series to be completed, will rise 67 storeys into the Mississauga sky while M5 is also under construction. The community’s final three structures are expected to then follow suit in the near future.

Rogers Real Estate Development and Urban Capital are developing the M City community, which was launched in 2017. Construction began two years later.

Last summer, project leaders said they were using the “most powerful pump in Canada” to deliver concrete high into the sky to get the latest skyscrapers in Mississauga’s downtown core, including M3, built.

The award-winning M1 and M2 towers stand 62 storeys in height.
