Yes, you can and definitely should buy Toronto Island ferry tickets in advance, especially during the summer months. The city of Toronto operates an online ticketing portal where you can purchase round-trip tickets for adults, seniors, and children. Buying in advance allows you to bypass the often massive lines at the ticket booths at the Jack Layton Ferry Terminal. However, there is a very important distinction to understand: an online ticket is not a reservation for a specific time. It is a general admission ticket that grants you entry to the boarding area. On busy weekends or holidays, even with a pre-purchased ticket, you will still have to wait in the queue to actually board the boat. By 2026, the city has improved the digital infrastructure, allowing you to scan the QR code on your smartphone at the turnstiles. The ferry serves three docks: Centre Island, Hanlan’s Point, and Ward’s Island; your ticket is valid for any of these routes. To avoid the biggest crowds, many locals recommend taking the ferry before 10:00 AM or considering a private water taxi, which costs more but offers a much faster, line-free experience.
