is was supposed to achieve Revenue Service Availability (RSA) on August 16, 2019. This is the handover to the city, not the launch. The launch will be about a month after RSA, sometime in mid-September.
UPDATE 2019-08-23: The LRT was handed over to the city on August 23, 2019. The launch date for LRT service to the public will be September 14, 2019 (at 2pm). END UPDATE
But there are multiple steps before we get to a full new network of Stage 1 LRT plus OC Transpo buses plus STO buses plus reconstructed roadways.
1. Ottawa LRT Stage 1 LRT Launch
The LRT will launch mid-September, but the current bus system will remain in place for three weeks. So it will be a mix of rail and parallel bus service.
from the OC Transpo Ready4Rail – Where will it go page.
The north-south Trillium Line 2 from Bayview Station will continue unchanged, but only until Q2 2020 (see below).
2. OC Transpo Bus Routes Optimised for LRT
Three weeks after LRT Stage 1 launch, specifically on October 6, 2019, the parallel bus service is discontinued, and Ottawa switches to a new bus network optimised for the LRT. This will mean the end of the Transitway (9x and 8x) buses on Albert and Slater; no more Transitway buses through downtown.
Map from OC Transpo New service types page.
Rapid buses (in blue above) will connect to the rail network at Tunney’s Pasture Station (westbound), Greenboro Station (southbound), Hurdman Station (southwest bound), and Blair Station (eastbound).
UPDATE 2019-08-23: The easiest way to figure out route changes will be to use the new trip planner, but if you want to know about a particular bus, you can start at the Ready for Rail – My Route page. END UPDATE
For more on Stage 1 LRT see Ottawa LRT Stage 1 maps.
3. STO Bus Routes Optimised for LRT
At some point (sometime in 2020) after the OC Transpo switch to new bus routes, STO will also change its routes. Which will bring buses back to Albert and Slater, as STO takes to these streets to run service through downtown to Mackenzie King Station.
For more on STO bus changes see STO bus changes after Ottawa LRT Stage 1.
Street Redesigns – Rideau Street and William Street
At some point, currently scheduled for September 2019 but presumably dependent on LRT launch, Rideau Street and William Street will be redesigned, with one goal being higher pedestrian capacity.
Street Redesigns – Albert Street and Slater Street
At some point, currently scheduled for Summer 2020, Albert and Slater will be redesigned with space for cycling (see proposed designs in the public information sessions). But note that Albert and Slater will not be bus-free; most notably there will be STO buses as indicated above.
Trillium Line 2 South – Stage 2 – Temporary Shutdown With Replacement by Bus Service
The Trillium Line (the north-south line) is scheduled to be shut down from Q2 2020 to 2022, while new stations and track are added for Stage 2. During shutdown a replacement bus service will run.
Full Service of New Stage 1 Transit Network and Redesigned Streets
Once all these steps are complete, presumably sometime in 2021, the downtown transit network and downtown streets will basically have their transformation complete.
LRT Stage 2
The next step will be LRT Stage 2, with new and updated segments scheduled for 2022 (Trillium Line 2 south), 2024 (Confederation Line 1 east) and 2025 (Confederation Line 1 west).
