Core idea

Mixed-use redevelopment by river and transit

Why it matters

National capital’s key brownfield revival

Description

A master concept plan prepared in 2019 by Canada's National Capital Commission for LeBreton Flats, a large tract of cleared federal land just west of downtown Ottawa. The plan, developed under the Building LeBreton initiative, lays out a mixed-use district organised around the Confederation Line light rail stations and the Ottawa River waterfront, combining housing, a potential major events venue, parks and cultural uses. It sets a phased framework for parcel-by-parcel disposition and development.

Significance

LeBreton Flats is one of Canada's longest-running planning sagas, cleared by urban renewal in the 1960s and left vacant for decades, so the 2019 plan represents the capital's principal brownfield revival effort. It illustrates the distinctive role of a federal capital commission as urban developer, and current Canadian practice of transit- and waterfront-oriented redevelopment with sustainability and affordability commitments.

What shaped it

The master plan (early 20th c.)
