Urban Retrofit Research Associate and urban design researcher Dr Jingyi Zhu reflects on the possibilities of urban retrofit and the inspiration she gained from the project study tour of Canadian cities. 

The Urban Retrofit study tour to Canada proved to be a thrilling experience on many levels. For two weeks I was fully immersed in urban environments that were completely new to me. I ventured betwixt and between city streets and alleyways, touched the walls that locals brush past daily, and experienced ordinary, novel and juxtaposing urban-scapes. The trip took place just three months after I joined Urban Retrofit. While grappling with readings on the theory and practices of urban retrofitting – many of which were still a bit foreign to me – I was lucky to have the opportunity of seeing and experiencing real life examples akin to those I’d read about. At the same time, I got the chance to speak behind the scenes with some of the visionary built environment professionals and communities that delivered them. The cherry on top was the group of colleagues I travelled with and the inspiring conversations we had as we walked, talked and observed. 

The four cities we visited – Halifax, Montreal, Toronto, and Hamilton – are all interesting in their own way. I was constantly asked which city I favoured, and truth be told, I cannot really choose one because they all have particular qualities that fascinate me. The steep and undulating streets of Halifax, the quirky juxtaposition of old and new and everything in between in Montreal, the Toronto skyscrapers that seemed to grow even taller every time we turned our gaze towards them, and the quaint and bustling James Street of Hamilton. I hope the photos I snapped of the buildings and streets – some of which I have shared in this blog post – can do justice to the richness of these cities. 

The breadth of project types we observed was remarkable. We navigated from regenerated waterfronts to post-industrial lands. We were shown how residential towers, neighbourhoods and infrastructure from half a century ago might be reimaged. We saw how new possibilities of living, socialising and mobilising can be inserted into buildings and neighbourhoods, lanes and alleys, both in urban and suburban environments. We even tasted the fruits grown on edge-of-city agricultural land that had been turned into a community-farm! The diversity of these spatial forms and social actions revealed to me the rich meanings of urban retrofit – the many different possibilities of repairing and revitalising existing urban fabrics and making great places. 

The Cogswell district revitalisation, Halifax: Where once an elevated highway interchange stood, a new urban district is emerging that will reconnect previously-severed neighbourhoods both spatially and via sustainable utility networks. 
The Bentway, Toronto: A cavernous, cathedral-like space has been created underneath the Gardiner Expressway which segments Toronto’s downtown core from its waterfront. A philanthropic gift has been creatively used to revitalise the forgotten space underneath the ‘bents’ – the concrete pillars that hold the structure aloft – and to fund an annual programme of arts and culture events. 
Housing retrofit projects by ModCity, Toronto: Infilling suburban sites that once housed single-family or ‘detached’ houses with duplex and triple-plex apartments as a way to address the problem of ‘missing middle’ housing – a term for the very limited amount of housing in Canada that is neither low density and detached or high density and tall. 
Technopôle Angus, Montreal: “Work-play-live” is truly possible when carefully planned, sustainable and mixed housing, in integrated with local businesses, inviting open spaces and green infrastructure. 

A recurring theme running through all the projects we visited was the importance of timing, leadership and vision. On the one hand, the projects offer so many varied lessons that any attempt to summarise a one-size-fits-all formula for success might be futile. On the other hand, we kept seeing how great things can be done when there are willing leaders (across the spectrum of public, private, community and not-for-profit sectors), an acute awareness and grasp of the available resources and how to use them (both capital and human), as well as a willingness to engage, negotiate and collaborate (again through the collective endeavour of various stakeholders). 

Alexandra Park, Toronto: The revitalisation and rebuilding of an affordable housing neighbourhood by Toronto Community Housing into a socially-mixed community where existing residents are at the forefront of planning the phasing of development and who have been able to stay in their homes as the new neighbourhood emerges around them. Any distinction between ‘market’ and ‘affordable’ homes is lost in the design of the buildings which aims to reduce the chances of community stigma and prejudice. 
Namur-Hippodrome, Montreal: An ambitious redevelopment of a former horse-racing track into a mixed-use and mixed-income neighbourhood. Here we learnt that reimagining places requires more than a neat blueprint, it also requires a clear and shared vision, a close-knit network of actors collaborating and negotiating, and opportunities for transitional uses that keep a place alive on the long road to revitalisation. 

Coming from an urban design background, I am particularly interested in the power of places and placemaking to shape urban experiences. In many of the projects we visited, the new places created and the processes that shaped them stitched together not only fragmented physical urban spaces but also people and communities. This really underscored the fact that high quality places can help to breakdown spatial and social barriers. I also have a long-term personal research interest in public space, and the projects we visited, to my great satisfaction, also demonstrated the diverse ways that public spaces can be created and operated. Collectively, these places show how public spaces are not, and should not be, the end result of development. Instead, they need long-term maintenance and creative programming to be truly alive and welcoming. The struggle for common and truly public space – both physical and social – is still real and evidenced in some of the fast-changes spaces and places we visited in Canada. This demands that we continue to reflect on the growth-oriented development paradigms that shape planning and design around the world and ponder possible ‘post-growth’ futures. 

Halifax waterfront: creating and operating vibrant waterfront public spaces alongside mixed-use developments. 
Jane and Finch Corner Commons, Toronto: Appropriating shopping mall parking space as communal, public space. While the communities’ voices have been incorporated into the next phase of (re)development, the future of the public space remains to be seen because a new transit corridor is likely to bring with it renewed pressure to develop dense market housing in the area which could drive up prices and push out existing resident. 

In the end, the single most inspiring thing that I took from the study tour was the passion of all those involved in the projects and the changes, both large and small, that they are pushing for. All cities, including the four we visited in Canada, have their own challenges and, at times, despair. It is the people who dedicate themselves to making great places that keeps me believing in a better and sustainable future that can be shared by all. 

Milton parc “Ruelles Vertes”, Montreal: Creating houses and public spaces that are truly for the community hinges on continuous citizen mobilisation and participatory democracy.
