Art Gallery of Ontario to unveil five-floor expansion in September 2027
The Art Gallery of Ontario (AGO) is set to unveil its new five-floor expansion on 25 September 2027. The additional 40,000 square feet will enhance the venue’s showcase of art, featuring nearly 400 works by Indigenous, Canadian, and international artists.
This project was initiated in 2022, following a substantial $35-million donation from Dani Reiss, the chairman and CEO of Canada Goose. AGO officials confirmed that the expansion is fully funded, thanks to backing from both federal and provincial governments, along with contributions from private donors.
The design of the expansion, known as the Dani Reiss Modern and Contemporary Gallery, is a collaboration among Diamond Schmitt, Selldorf Architects, and Two Row Architect. Positioned to overlook Toronto’s Grange Park, it will seamlessly connect to the existing Frank Gehry-designed structure.
In addition to expanding its exhibition space, the expansion aims to achieve sustainability, operating without fossil fuels and has received Zero Carbon Building Design certification. This designation makes the AGO the first Canadian cultural institution of its size to attain such recognition.
Since its founding in 1900, this will mark the museum’s seventh expansion, further solidifying its role as a significant cultural hub in Toronto.
