Major projects

In this section

The O-Train Confederation Line is a state-of-the-art LRT system and Ottawa’s largest transportation infrastructure project since the building of the Rideau Canal.

Get ready for the future. Get involved in creating a livable and resilient Ottawa. 

These tunnels will hold up to 43,000m3 of sewer overflow during major rainfalls, the equivalent capacity of approximately 18 Olympic sized pools. Once rainfall has subsided, this water will then be treated and returned safely to the Ottawa River.

Over the next two decades, many exciting projects in LeBreton Flats will help to transform the area into a thriving community.

We’re embarking on the most prominent project in our history – our Central Library will be an inclusive, dynamic space for creativity and learning.


Fifth Street Bridge

The Rideau Canal Crossing project involves the design and construction of a 5 metre wide by 123 metre long, linear multi-use pedestrian and cyclist bridge over the Rideau Canal. 

Beginning on Monday, March 11, the Lewis and McLeod street crossings at Elgin will be closed.
