I would posit that the fact that we inhabited a New World that had been entirely unknown to the Old, made us more receptive to the idea that there could be other words with sentient life.
Canada doesn't have an independent Anglophone culture from that of the United States. At most, it's a regional subculture, like Southern literature is a subculture.
Latin America went more for magical realism, which to a large degree reflects the syncretism of Catholicism and native religions.
Magical realism is really only an artistic movement though? (most prominent in painting, as well as in certain writers, most notably Gabriel García Márquez)
I actually did stucy magical realism a bit in high school; but it was on my Spanish literature classes and was described as just a literary movement whose biggest representative was Gabriel García Márquez (and indeed it also involved watching the horrible movie adaptation of
Crónica de una Muerte Anunciada, though my brother instead did actually read another of his books in class:
Relato de un Náufrago)
Not a religious thing though.
