Water Taxi Hours The Toronto Harbour Water Taxi, on the other hand, does offer late service from the Islands. Its operating hours are 8 a.m. to 12:00 a.m. Sunday through Thursday and 8 a.m. to 1:00 a.m. on Friday and Saturday. The Otter Guy Water Taxi also has later hours, running all week from 9 a.m. to 1 a.m.

As of the 2026 season, private water taxis in Toronto—such as Toronto Harbour Tours or Otter Island Taxi—generally run significantly later than the city-operated public ferries. During the peak summer months (June through September), most water taxis operate until midnight or 1:00 AM on weeknights, and often as late as 2:00 AM on Friday and Saturday nights. This late-night service is particularly popular for residents of the island or visitors attending evening events at the Royal Canadian Yacht Club or Ward’s Island. It is important to note that after 9:00 PM, many companies switch to an "on-demand" model rather than a fixed schedule, so you may need to call ahead or use their mobile app to request a pickup. Prices are typically around $12 to $15 CAD per person for a one-way trip. During the "off-season" (spring and fall), hours are usually scaled back, with most services ending by 10:00 PM. Always check the specific provider's live schedule, as service can be suspended instantly due to high winds or heavy fog in the harbor.
