How It Works: The CN Tower Light Show

Everyone who lives in Toronto has seen the CN Tower lit up. It becomes a pinnacle in the skyline at night because of the bright lights and constantly changing colours, but did you know that those colours actually hold a meaning? Every day of the year the lights shine a different colour, sometimes relating to a local or worldwide event, to bring awareness to a particular cause, or to celebrate a holiday.

The lights are controlled by a microprocessor that can produce over 16.7 million different colours. Made up of thousands of different fixtures, each one is unique and can be specifically controlled, which is how they get all those cool, colourful effects. Much like the light fixture on our building, the LED lights used on the CN Tower are directional, which means that the light is controlled to reflect in a certain direction as to not disturb nearby buildings.

A few examples of our favourite CN Tower lighting shows include:
