No, it isn't. The Canterbury Tales is more like a anthology of separate tales. It showcases a wide range of characters and their narratives, rather than following the typical structure of a novel.
Definitely fiction. The Canterbury Tales presents imaginative and often humorous narratives that are crafted by the author's creativity rather than being based on real events or people.
The Canterbury Tales is an interesting mix. It's not purely a poem or a novel. It's a compilation of stories told by different characters in various styles.
