Saw this coming home from work one day couple months ago. Couldn’t hold myself back and pulled over on the 403 just south of Dundas. Ironically the rainbow from this perspective ends at a company called LaserNetworks which happens to have the spectrum of colours as it’s logo.
This is about 7-8 pictures shot from my handy dandy Nokia 5230, stitched together using Adobe Photoshop’s Photomerge feature.
