Blue Night Network

If there is a Blue Night route on the same street, its first trip will then follow at a suitable interval after the last regular run.

In the morning, regular bus and streetcar service mostly takes over from the corresponding Blue Night routes around 5:30 a.m, or 8:00 a.m. on Sundays.

Most routes are operated by TTC's fleet of low-floor buses, where applicable, making them fully accessible for handicapped and wheelchair users.

The report pointed out that the importance of the original "demand generators" for overnight public transit had declined.

But since "one of the TTC's primary goals is to maximize mobility and accessibility to transit service", the report's recommendation was to redesign the system, not eliminate it.

Most of Toronto has a squarish grid of main streets that originated as early 19th-century concession roads,[6] and are spaced at 1+1⁄4-mile intervals (about 2 km).

By running overnight buses along every second road in the grid, all parts of Metro would be reached and 86% of the population would be within a 15-minute walk (taken as 1.25 km or 3⁄4 mile).

The report recommended reducing service frequencies after 10 p.m. on certain routes in order to offset the increased costs.

Until this time, with the exception of buses that replaced subway lines, it had been understood that overnight transit was provided by regular routes that happened to have 24-hour service.

The name Blue Night Network was adopted, and with it the 300-series route numbers described above, and a new colour-coding for bus and streetcar stops.

But other routes have been extended or added over the years, including one case (312 St. Clair in 2000) that required a mode conversion from streetcar to bus.

In February 2003, two Blue Night routes were extended to reach Toronto Pearson International Airport.

This has brought the Blue Night Network up to a total of 24 routes, serving 97% of the city's population within a 15-minute walk.
