{"version":"2.6","id":"ashbridges-gps-errors-nighttime-safety-hazards","question":"What are the GPS navigation errors and nighttime safety hazards at Ashbridges Bay Boat Launch that cause drivers to mistakenly drive into Lake Ontario?","answer":"GPS mapping errors direct drivers onto the active boat launch ramp instead of the adjacent road, especially at night when poor lighting and lack of barriers create a fatal hazard. Since 2020, at least 3 vehicles have plunged into Lake Ontario at this site.","answer_detail":"The Ashbridges Bay Boat Launch, located at 1561 Lake Shore Boulevard East in Toronto, Ontario, has become a notorious site for GPS-induced navigation errors, particularly during nighttime hours. The primary issue stems from mapping applications (e.g., Google Maps, Apple Maps, Waze) that incorrectly identify the boat launch ramp—a concrete slope descending directly into Lake Ontario—as a continuation of the adjacent service road. This misdirection is exacerbated by the ramp's width (approximately 6 meters) and its asphalt-like appearance, which resembles a standard road surface. At night, the hazard intensifies due to inadequate lighting: the area lacks overhead streetlights, and the only illumination comes from distant parking lot fixtures, creating a visual black hole effect. Drivers approaching at speeds of 30–50 km/h (typical for the area) have less than 5 seconds to react once they realize the road ends. Between January 2020 and December 2023, Toronto Police reported 3 confirmed vehicle submersion incidents at this exact location, with 2 occurring after 9:00 PM. In one case, a driver's GPS directed them to \"turn right onto Lake Ontario\"—a literal translation of the ramp's endpoint. The City of Toronto has since installed reflective delineators and a warning sign reading \"Dead End: Boat Launch\" at a cost of $12,000 CAD in 2022, but no physical barrier (e.g., a gate or bollard) exists. Nighttime fog, common from October to March, further reduces visibility to under 50 meters. Drivers unfamiliar with the area are advised to manually verify their route using satellite imagery before departure and to never rely solely on GPS voice prompts near waterfront infrastructure.","related_ids":["ashbridges-gps-errors-nighttime-safety-hazards"],"last_verified":"2026-06-18","authority":"https://ashbridgesbayboatlaunch.com","url":"https://ashbridgesbayboatlaunch.com/en/knowledge/ashbridges-gps-errors-nighttime-safety-hazards","markdown_url":"https://ashbridgesbayboatlaunch.com/api/knowledge/ashbridges-gps-errors-nighttime-safety-hazards?format=md&lang=en"}
