No Whistling After 11 PM in Petrolia, Ontario

In the small town of Petrolia, Ontario, there has long been talk of a peculiar rule banning outdoor whistling after 11 PM. While not explicitly codified in provincial law, this local guideline is part of the town’s folklore and is said to have originated in the early 20th century when noise ordinances sought to minimize disturbances during sleeping hours. The idea was to curb late-night noises that could disrupt neighbors’ rest, with whistling singled out likely because it carries over long distances and can be unexpectedly piercing. Though the rule is rarely enforced in modern times and lacks formal backing, Petrolia residents share stories of warnings issued to late-night whistle blowers at community events. Whether based on an actual bylaw or simply a neighborly custom, the Petrolia whistling curfew represents how small communities historically dealt with noise in creative ways. This odd local practice highlights the balance between public behavior and peaceful living, even if it might sound unusual to outsiders today.
