Lighting The Luminous Veil

What has 35,000 LED lights that can change colour when the wind, temperature and seasons change?

The Bloor Street Viaduct’s Luminous Veil.

Historically, the Bloor Street Viaduct was one of the most significant infrastructure projects ever undertaken by the City of Toronto. Constructing the “Prince Edward” bridge across the Don Valley would connect a sprawling young Toronto and lead to its incredible expansion and growth in ways that no one could have imagined back in 1918.

Years later, in 2003, the Luminous Veil was designed and added as a safety feature. Artist, architect and creator of the Veil, Dereck Revington, had always intended it to be illuminated. Unfortunately, the City could only afford to build the basic structure at the time.

Fast forward to February, 2015. With the Pan Am Games coming to Toronto in the summer of 2015, the time was right for a very special beautification project, one that would not only welcome the world but also become a permanent legacy for the enjoyment of all Torontonians.

The Challenge

A tight deadline — the project had to be completed in time for pre-Pan Am Games celebration and torch relay on July 4, 2015.

Technical Details

In order to create an ever-changing light show, Mulvey & Banani designed a complex 450-metre-long LED-based lighting system. Thanks to sensors, 35,000 LED environmentally responsive lights react to changes in wind speed and temperature.

A Luminous Night

On the evening of July 4, 2015, Torontonians filled to the Bloor Street Viaduct for the premier illumination of the Luminous Veil. The lively celebration included the Toronto 2015 Pan Am torch relay and plenty of music.
