SEPTEMBER 29 TO OCTOBER 22 One of Giuseppe Verdi’s most remarkable works returns to the stage in a new production by the Canadian Opera Company. The three-act Rigoletto presents the tragic tale of a court jester who seeks to avenge his daughter after she is seduced and deceived by a cold-hearted duke. Yet, despite his best efforts, the poor fool stands to lose all that matters to him. Featuring both established and rising opera stars, the COC’s staging is set to entertain and enthrall in equal measure, thanks to Verdi’s beloved arias and a heartrending libretto inspired by a Victor Hugo play.
