Cogswell District
Background
Costing CAD $128 million and encompassing the complex task of dismantling 6.5-hectares of former highway infrastructure, the Cogswell District revitalisation project ranks among the largest urban retrofit efforts ever undertaken in Atlantic Canada. From the late 1960s onwards, the Cogswell area was dominated by the Cogswell Interchange – a large and clunky piece of highway infrastructure that separated downtown Halifax from its historic North End and, at the time of its construction, resulted in the displacement of African Nova Scotian and Mi’kmaq communities. For decades, this so-called “highway to nowhere” symbolised both loss and unrealised potential in Halifax’s urban core.
Beginning in the early 2000s, local community groups and municipal leaders called for the removal of the obsolete interchange, envisioning it as chance to both restore the area and create a catalyst for equitable, climate-friendly urban development. The subsequent project, led by the Halifax Regional Municipality’s newly formed Major Projects Office, aims to reconnect neighbourhoods, restore a lost street grid, foster transit-oriented development, create a series of developable land parcels and deliver a large-scale model of on-going urban retrofit.
Location:
Downtown Halifax, Nova Scotia, Canada
Typology:
Mixed-Use Neighbourhood, Infrastructure Reuse
Time frame:
Construction commenced 2022; completion of public infrastructure anticipated late 2025, followed by the initiation of the first private development
Challenges
The legacy of displacement and the fragmented urban form around the Cogswell interchange created numerous and complex technical, social and political challenges. These included:
- Balancing past harms and community reconciliation with new growth pressures and land value expectations;
- Large-scale infrastructure demolition, complex sequencing and active utility coordination (for example with Halifax Water, Nova Scotia Power, etc.);
- Mitigating flood risks and accommodating the significant grade changes that exist in the area;
- Managing political pressures relating to operating budgets, procurement policies and intergovernmental negotiations; and,
- Fostering public trust amid scepticism about the proposed development by commemorating those communities that were uprooted to build the highway interchange and a commitment to genuine community engagement for the emerging project.
Implementation
The Cogswell District initiative is managed by Halifax Regional Municipality, the regional local government. Its aim is to create a transit-oriented, net-zero-ready neighbourhood. The project has unfolded in multiple phases, beginning with the systematic dismantling of the road interchange and the creation of a walkable, transit-connected street grid in its place. The new Cogswell District reintroduces historic urban blocks, new winding boulevards, wider sidewalks, and active transportation corridors, including bi-directional bikeways and greenways that reconnect the North End with downtown and the Halifax waterfront.
At the heart of the net zero ambition lies a new district energy system that extracts heat from the adjacent municipal wastewater plant. This offsets the neighbourhood’s heating needs and reduces reliance on fossil fuels. Phased land sales are being tactically managed by the municipality to ensure value for money is achieved and revenue is maximised. Any surpluses will be directed toward affordable housing. Robust social procurement and commemoration programmes, such as naming new parks and streets after displaced families and installing public art with community input, also embed social equity and memory into the public realm.
Results
Reimagined as a resilient and inclusive urban neighbourhood, the Cogswell District will eventually become a mixed-use office, commercial and residential area for more than 2,500 residents that prioritises walking and active transportation. New parks, plazas and green spaces—such as Granville Park, Overlook Park and Poplar Park Garden—anchor civic activity, while infrastructure investments strive to deliver long-term climate resilience through integrated stormwater management, flood mitigation strategies and a district energy system that must be used by future developments.
Social and economic benefits include expanded opportunities for underrepresented groups, strengthened neighbourhood ties, as well as creating a vibrant and more accessible gateway into downtown Halifax that celebrates the city’s diverse histories.
While the long‑term financial viability of the project remains contingent on the sale and development of the newly created land parcels, Halifax Regional Municipality expects to achieve full cost recovery and a potential surplus.
The project stands as a model of how cities can repair past harms, embed equity and build sustainability through planning and design.
Lessons learned
The Cogswell District project offers a number of instructive lessons:
Reckoning with History
Acknowledging and commemorating displacement can be a foundation for healing and more just urban futures.
Adaptive Reimagining of Infrastructure
Converting obsolete assets into sustainable, people-centred spaces unlocks social and economic value.
Layered Governance and Partnerships
Success hinges on sustained collaboration across multiple government, private sector and community partners and stakeholders
Strategic Land Management
Leveraging land sales for public benefit—especially affordable housing—ensures that redevelopment serves equity goals.
Long-term Resilience
Embedding energy, accessibility, mobility and flood mitigation into masterplanning creates the conditions for a neighbourhood to adapt to future urban challenges.
