As the Stage 3 plan is neither complete nor funded, there isn’t a lot of definitive detail.
In Stage 3 Ottawa may extend commuter rail west to Kanata and south to Barrhaven, both from the west side of Line 1 (the red line, also called the Confederation Line).
It may also extend rail to Quebec over the existing but currently unused Prince of Wales Bridge, although there is also a Gatineau proposal to create a west-end rail system in Quebec that is proposed to run across the Portage Bridge.
Here is a high-resolution Stage 3 map
from slide 109 of the Stage 2 Light Rail Transit Project: Technical Briefing – February 22, 2019 (PDF, Internet Archive) – Stage 3 extensions to Kanata and Barrhaven in above image in purple. Please note this linked technical briefing presentation is all about Stage 2, it only has a single slide about Stage 3 at the end.
Based on Stage 2 completing in 2025, we would expect Stage 3 to be completed in the 2030-2031 timeframe, assuming they can secure Stage 3 funding.
Note that the extension across the Prince of Wales Bridge may be complicated by STO’s proposed rail plan that would run instead on the Portage Bridge.
(If you landed here looking for information on Stage 2, please see my previous Ottawa LRT Stage 2 maps post instead.)
To some extent you can get a sense of the Stage 3 vision from the transportation network in the 2013 Transportation Master Plan. (The Transportation Master Plan normally would have been updated in 2018, but the city wants to complete Stage 1 of the rail system first.)
This map was a vision for the future (roughly 2028-2031 timeframe). The actual network will depend on many different factors including funding and route optimisation. Red is rail (Light Rail Transit), blue is bus (Bus Rapid Transit).

UPDATE 2018-02-15: I would characterize the surface rail (tram) line running along Carling depicted in the 2013 map above as highly speculative. If implemented as a tram, sharing the roadway with cars, it would have the same reliability problems other North American streetcars have. (This type of tram with shared road space is common outside North America, and works well there due to a variety of factors including different road designs and slower vehicle speeds.) END UPDATE
UPDATE 2018-02-23: There has been a detailed announcement about Stage 2, including a new prospective map for Stage 3 (shown at the top of this blog post) and a new timeline.
Mayor Jim Watson tweeted
We are setting the stage for future
#OttLRT expansion of 12km to Kanata-Stittsville [from Moodie Station] and Barrhaven. Additionally, the Baseline Station is protected for a future 10km extension to Barrhaven, and Bayview Station is protected for a 1.5km interprovincial rail link to Gatineau [over the Prince of Wales Bridge].
[Bracketed comments] and
He tweeted a map with Stage 3 rail extensions in blue, but this is usually used for Bus Rapid Transit, so I changed the extension colour to purple (in the map at the top of this blog post).
Stage 3 is now at least six years (2025) away from being finalised and started, based on the new timeline for Stage 2. This would mean completion of Stage 3 in the 2030-2031 timeframe.
END 2018-02-23 UPDATE
Ottawa’s east-west commuter rail Confederation Line (Line 1) is completely grade-separated, which means that it never intersects with car traffic. This is absolutely the correct design for a high-reliability commuter rail network. When extending the network into car-designed Kanata, however, it has the unusual result of a recommendation that part of the line be elevated. Any time you put rail under the ground or elevated above ground level it’s more expensive, but I guess there are a lot of highways for the Kanata extension to cross.

The separate Kanata Light Rail Transit Planning and Environmental Assessment Study is complete. I obtained official final versions of the January 2019 files from the City of Ottawa and have made them available on the Internet Archive at https://archive.org/details/klrt-epr-final-rev-3
In the map below, the proposed corridor and station locations are shown, with elevated portions of the line in green, at-grade in blue, and underground in yellow.
Map from section 8-3, page 168 of the August 2018 Report Draft from DropBox.
Stations heading west and then south:
- Moodie Station (planned for Stage 2)
- March Station
- Kanata Town Centre Station
- Terry Fox Station
- Didsbury Station
- Campeau Station (line turns south after this station)
- Palladium [stadium] Station
- Maple Grove Station
- Hazeldean Station

In the map above “LMSF” means Light Maintenance and Storage Facility.
The older diagram below from the earlier May 2018 report to City Council – Corridor Options (PDF) also shows the stations.
Barrhaven is new addition to the LRT evaluations, although a rail line to Barrhaven was always envisioned as part of the Ultimate Network. The line would connect south from west Line 1 Stage 2 Baseline Station.

Prince of Wales Bridge
You can see in the maps at the top of this blog post that there is a plan for OC Transpo’s commuter rail service to cross the Prince of Wales Bridge, but I don’t know any details. I don’t even know whether they would use Line 1 or just extend Line 2 northwards. I’m happy to add details if they are provided.
UPDATE 2020-05-17: I’ve written more about The future of the Prince of Wales Bridge. There is currently no funding to do anything with it. END UPDATE
These are very early days, so rely on the City of Ottawa for official word on the specific rail lines and stations for Stage 3 LRT.
