Hit pause on your plans—tonight, Toronto trades the usual nightlife for art you can walk through. Nuit Blanche Toronto returns for its 19th edition, taking place overnight from October 4 into the morning of October 5. This year, the cultural event invites artists to 'translate the city' by exploring the intersections of language, history and identity within an ever-evolving urban landscape. Artist Ellen Pau's 'The Eye of Wisdom' appears as a large-scale projection incorporating Hong Kong Sign Language as a public love letter. Head downtown and explore curator Charlene K. Lau's 'Poetic Justice,' which delves into land, treaties and the city's layered past. Look up and you might spot Cassils' project 'Undersight,' flashing 'deemed suspect' words into the evening sky using Morse code just like a Bat-Signal.

Years before tonight's marathon of art, French artist JR left his mark on the city. His 2015 project 'Inside Out – The People's Art Project,' featured in today's image, turned Nathan Phillips Square into a giant wall of black-and-white portraits. The installation broke down generational and racial barriers, becoming a social phenomenon that over 250,000 people from more than 120 countries have joined. His work keeps giving people the chance to share their own messages on a monumental scale. Your face next?
