Erin Della Mattia Editorial

Brampton, ON


Award-winning freelance editor specializing in children's books, trade fiction, and non-fiction.

I provide a range of editorial services including copy editing, substantive editing, and stylistic editing to publishers, traditional authors, and self-publishing authors.

I excel at both high-level stylistic edits and soft-touch copy edits and I tailor my edits to suit the needs of each individual writer and manuscript. I strive to practise consent-based editing, which uses open communication, flexibility, empowerment, and boundaries to create a positive editing experience for both author and editor.

If your goal is to query literary agents or publishers, I can provide you with actionable, strengths-oriented feedback and structural edits that will take your manuscript to the next level. If you plan to self-publish, I can help to highlight the artistry of your writing and make your book reader-ready. I welcome you to email me or visit my website to learn more about how we can work together.

While I am happy to edit all kinds of books, I have a soft spot for fantasy, dystopian, and speculative literature for readers of any age.


I earned a Certificate in Publishing at Toronto Metropolitan University (formerly Ryerson University), where I also completed my MA in Literatures of Modernity. I have a BA in English and Creative Writing from York University, and I also spent several years studying in the University of Toronto’s English doctoral program.
