H. E. Casson is a queer, disabled/mad poet, voice actor, and storyteller. They have lived in every borough of Toronto (Tkaronto), located on land included in Treaty 13 and the Williams Treaty.

They decided they were a poet in the fifth grade, and words have helped them survive and celebrate experiences of homelessness, group home living, and institutionalization. H. E. has supported their notebook collection by working in childcare, hospitality, and the arts. Throughout, they have built a found family of creators, caregivers, connoisseurs, and clowns.

They are a Best of the Net, Pushcart Prize, and Audio Verse Award nominee, with work selected for inclusion in the Best Indie Speculative Fiction anthology. H. E. has had pieces shared by the League of Canadian Poets, Apparition Lit, The Quilliad, Serotonin, and Taco Bell Quarterly--among others. The Al Purdy A-frame Association selected them to serve as one of the 2022-2023 Writers-in-Residence.
