If there's no better way to ensure your city attracts international attention than high-profile architectural commissions, then Toronto has learned its lessons well (though it's still Zaha-free). The latest? Daniel Libeskind's L Tower (pictured), which was supposed to both revamp the city's Sony Centre for the Performing Arts and contain luxury housing. While the condo project is moving ahead, the new arts center isn't: Funding has dried up, and so ambitious plans have been curtailed (similar to what happened to Libeskind's design for the city's Royal Ontario Museum. Fool Toronto once...). Still, it should offer an intriguing addition to the skyline when it's completed—or at least some aesthetic competition to the city's mainstay landmark, the CN Tower.
