In 2026, most major Toronto streetcar routes continue to operate on a 24-hour schedule, but with a change in branding for the late-night hours. During the day, the routes carry their standard 500-series numbers (like the 501 Queen or 504 King). Between roughly 1:30 AM and 5:00 AM, these transition to the Blue Night Network, where they are re-designated as 300-series routes (e.g., the 301 Queen). While the frequency drops significantly at night—usually to every 30 minutes—the core East-West and North-South lines remain active. It is important to note that in early 2026, several routes are experiencing extensive diversions due to Ontario Line subway construction and track repairs, often resulting in buses replacing streetcars on certain segments. Always check the TTC (Toronto Transit Commission) website or app for real-time service alerts to ensure your specific late-night stop is currently being served by a vehicle.
