Summer 2025 | May 23 – October 5, 2024
The Bentway’s summer exhibition of free public art brings together artists, designers, and researchers to explore how new thinking about sun and shade can help cities adapt to rising temperatures and create more comfortable urban spaces.


Throughout the twentieth century, few forces have impacted the shape of North American cities as significantly as the sun. Driven first by public health objectives and later by an insatiable desire for daylight and broad views, urban centres and the spaces they support are largely celebrated for the ways in which they maximize access to light. Over time, unobstructed rays became synonymous with urban progress and yet, as temperatures rise every year, our sun-drenched streets and public spaces are becoming less and less comfortable. Extreme heat events are predicted to rise in the Greater Toronto Area from 20 days per year now to 66 days per year by 2050, leading to increased risk of illnesses and mortality.
In light of these accelerating thermal changes, there is a need to reexamine the critical relationship between sun and shade. Many cities have long grappled with extreme heat and recognize the vital and democratizing role that shade plays: it offers shelter and relief; it creates new places to gather safely; and it is an unintended choreographer mapping and remapping cool corridors for safe travel.
Shade is an essential public resource.
In Toronto, shade’s changing role is palpably felt and seen in spaces below the Gardiner Expressway. Our elevated downtown highway is the city’s largest continuous canopy, casting a shadow over 6.5km in length. This roof provides a welcome cover from intense heat in the warmer seasons and the spaces underneath offer the opportunity for a new type of public space that balances the benefits of sun and shade.
How can we collaborate with the sun in new ways?
How will shade help to define new spaces for civic life?
The Bentway’s summer exhibition of public art, Sun/Shade, brings together artists, designers, and researchers from Toronto and beyond to deploy the sun and shade as creative tools, revealing how new thinking about familiar resources can improve urban life. This summer, we invite you under the highway to shine a light on the benefits of shade.
The Sun/Shade exhibition was inspired and informed by the City of Toronto’s Thermal Comfort Guidelines, which are re-shaping the way we plan and build public space. Read more about the guidelines here.
