The reason for fireworks tonight, October 13, 2025, is that it is the last night of the Niagara Falls Fireworks Series, which runs every night at 10:00 PM from May 16 until October 13, 2025. This series is Canada's longest-running fireworks event, with nightly displays launched above the Horseshoe Falls, turning the sky into a colorful spectacle throughout the summer and early fall season.
