Here are people that I heard somewhere that they may have lived in Toronto, even for a short period of time. I can't confirm it though - SO PLEASE HELP ME OUT if you can confirm it.

• Billy Bishop (he was married in Toronto)
• Duke of Kent, Queen Victoria's Father
• Al Jolson
• Iman (hosts Project Runway Canada shot in Toronto for two seasons, so presumably she lived her during this time)
  
• Anna Leonowens (King and I)
• Gina Lollobrigida
• Lois Maxwell - actress best known as Bond' original Miss Moneypenny, wrote a column for the Toronto Sun for many years, but cannot confirm whether she actually lived here
• Iggy Pop
• Joaquim von Ribbentrop - Nazi war leader, definitely lived in Canada prior to WWI ,but not sure where

Prince Rogers Nelson - someone anonymously added "Prince", this is his real name. I'm so glad someone is helping me out! Prince did buy a house here and spent some time (not sure how long though) before divorcing his wife. I'm sure he won't probably be sticking around any more.
