From Wikipedia:

" Place to Stand, A Place to Grow (Ontari-ari-ari-o!) is the unofficial anthem of the Canadian province of Ontario. The song was written as the signature tune for a movie of the same name that was featured at the Expo 67 Ontario pavilion.

The song was written by Dolores Claman, who also wrote the Hockey Night in Canada theme, with lyrics by Richard Morris. Lyrics for a French version were written by Larry Trudel.[1]"
