A Place to Stand, A Place to Grow (Ontari-ari-ari-o!) is the unofficial anthem of Ontario. It was featured at the Expo 67 Ontario pavilion, so Ontarians my age and younger know it best from Jim Carrey's appearance on Late Night with Conan O'Brien when he came to Toronto for four episodes.
It's cheese, but it's beautiful Canadian cheese, and it was written by Dolores Claman who wrote another Canadian classic, the theme to Hockey Night in Canada. Here it is, but consider yourselves warned. It's very, very catchy.
