Plans for Toronto’s long-awaited opera house are unveiled. It’s a $150 million 2000-seat theatre. “Our ambition is to position this opera house among the top two or three in the world. If you look at what has worked for 400 years, you have a reasonable chance of success. Once you go over 2,000 seats (Roy Thomson Hall originally sat more than 2,800 people), you have made an unacceptable compromise.”
