Four major streaming services—Netflix, Prime Video, Peacock, and AMC+—showcased upcoming horror and thriller series at the Toronto International Film Festival, highlighting October's growing significance as a competitive period for streaming releases. The scheduling demonstrates how streamers are now treating the autumn month as prime territory for dark, atmospheric content, much as they have traditionally done with other seasons for different genres.

The featured releases include Carrie (Prime Video, October 7th), directed by Mike Flanagan and adapted from Stephen King's novel with a modernised narrative centred on cyberbullying; Below (Netflix, October 8th), a six-part series about an ancient sea creature terrorising a Newfoundland fishing village and starring Josh Hartnett; Crystal Lake (Peacock, October 15th), a prequel to Friday the 13th exploring Pamela Voorhees' tragic backstory with Linda Cardellini; and Yaga (AMC+, October 23rd), a supernatural detective series. Each series combines horror or thriller elements with character-driven narratives emphasising family drama and emotional depth alongside scares.
