Who better to promote Toronto’s slumping condo market than the Material Girl.

Madonna, whose 2012 tour was the top-grossing act of the year worldwide with $296.1 million in revenue, will lead an “Addicted to Sweat” dance class next month at her Hard Candy Fitness studio inside Aura, a new 78-story condo tower in Toronto. The luxury development will also feature a sculpture-studded public gallery, a marble-lined lobby and a five-bedroom penthouse priced at $17 million.
