Yes, there is a tunnel to Toronto Island, but it is exclusively for pedestrians and is located at Billy Bishop Toronto City Airport (YTZ). Completed in 2015, the 853-foot pedestrian tunnel runs 100 feet beneath the Western Channel of Lake Ontario, connecting the mainland pavilion to the island airport terminal. It features four moving walkways and takes about six minutes to traverse. However, it is important to note that this tunnel does not connect to the main Toronto Island Park (where the beaches and Centreville Amusement Park are located). To reach the public park areas, you must still take the historic Toronto Island Ferry from the Jack Layton Ferry Terminal or a private water taxi. There is no car tunnel to any part of the islands, as they are one of the largest urban car-free communities in North America. For travelers using the airport in 2026, the tunnel offers a fast, weather-proof alternative to the 90-second ferry ride, but for those looking for a picnic at Centre Island, the ferry remains the only practical and scenic route from downtown.
