• Smart city technologies do not necessarily increase the level of citizen engagement. • The idea of a public is a plural, emergent phenomenon that requires careful consideration by planners to enhance equity and participation. • Critical perspectives should consider the way publics are formed in relation to smart city technologies. In efforts to become "smart cities," local governments are adopting various technologies that promise opportunities for increasing participation by expanding access to public comment and deliberation. Scholars and practitioners encounter the problem, however, of defining publics-demarcating who might participate through technology-enhanced public engagement. We explore two case studies in the city of Calgary that employ technologies to enhance public engagement. We analyzed the cases considering both the definition of publics and the level of citizen participation in areas of participatory budgeting and secondary suites. Our findings suggest that engaging the public is not a straightforward process, and that technology-enhanced public engagement can often reduce participation towards tokenism. City councillors and planners need to critically confront claims that smart cities necessarily enhance participation. Moving beyond tokenism requires understanding "public" as a plural category. Municipal governments should seek to proactively engage citizens and communities utilizing helpful resources including, but not limited to, digital tools and smart technologies. This would allow planners to keep a "finger on the pulse" of publics' concerns, better identifying and addressing issues of equity and social justice. It is also important to consider how marginalized publics can best be recognized in order to bring their concerns to the fore in decision-making processes.

Introduction Despite the accumulating Canadian evidence regarding the relations between urban form and health behaviours, less is known about the associations between urban form and health conditions. Our study aim was to undertake a scoping review to synthesize evidence from quantitative studies that have investigated the relationship between built environment and chronic health conditions, self-reported health and qual¬ity of life, and injuries in the Canadian adult population. Methods From January to March 2017, we searched 13 databases to identify peer-reviewed quantitative studies from all years that estimated associations between the objectively-measured built environment and health conditions in Canadian adults. Studies under¬taken within urban settings only were included. Relevant studies were catalogued and synthesized in relation to their reported study and sample design, and health outcome and built environment features. Results Fifty-five articles met the inclusion criteria, 52 of which were published after 2008. Most single province studies were undertaken in Ontario (n = 22), Quebec (n = 12), and Alberta (n = 7). Associations between the built environment features and 11 broad health outcomes emerged from the review, including injury (n = 19), weight status (n = 19), cardiovascular disease (n = 5), depression/anxiety (n = 5), diabetes (n = 5), mortality (n = 4), self-rated health (n = 2), chronic conditions (n = 2), metabolic condi¬tions (n = 2), quality of life (n = 1), and cancer (n = 1). Consistent evidence for asso¬ciations between aggregate built environment indicators (e.g., walkability) and diabetes and weight and between connectivity and route features (e.g., transportation route, trails, pathways, sidewalks, street pattern, intersections, route characteristics) and injury were found. Evidence for greenspace, parks and recreation features impacting multiple health outcomes was also found. Conclusion Within the Canadian context, the built environment is associated with a range of chronic health conditions and injury in adults, but the evidence to date has limi¬tations. More research on the built environment and health incorporating rigorous study designs are needed to provide stronger causal evidence to inform policy and practice.
