I've been to the Four Seasons Centre twice: once for an opera (Rigoletto in 2011/12) and once for Operanation, their annual fundraising event for young professionals. The venue is absolutely stunning, a major attraction in Toronto, I think. The Canadian Opera Company is a major player in the opera world, too. Their productions are fresh, innovative, and exciting. There are also great options for cheap tickets, especially for those under 30. I highly recommend.
