Home to the Canadian Opera Company, the Four Seasons Center for the Performing Arts is a gorgeous building both inside and out. The exterior features a glass wall allowing light to shine in or out depending on the time of day, and the inside is a spectacular open space with four balconies. It also houses the longest free-spanning glass staircase in the world. Besides being beautiful, it is also quite functional with the main room holding over 2,000 spectators. The smaller amphitheater provides free shows throughout the year.
