2nd World Congress and Expo on Optics, Photonics & Laser Technology

Worth noting — this isn't a Toronto after-work listing. The 2nd World Congress on Optics, Photonics and Laser Technology is an international expo held in Seoul, South Korea in November 2026. It's a fascinating world for science and tech enthusiasts, but it's not something you can pop into after leaving the office on a Tuesday. We'll flag relevant Toronto-based tech and science events as they come up. Perfect for after work — drop in solo or bring a friend. No experience necessary.
