In slightly-old news, the CBC aired a program last week announcing the Greatest Canadian Invention: the Toronto-created insulin. Other notable Toronto inclusions are the electron microscope, the G-suit, the light bulb (with the patent sold to Edison, somehow a very Toronto thing to do), pablum, and UV degradable plastics. The somewhat random list is still up on the CBC's website, although if there's one selection that isn't debatable it's poutine. I think I would have put it ahead of five-pin bowling, at least. If we had to come up with a list of the Greatest Torontonian inventions, what would top it? I'd nominate the Peameal Bacon Sandwich, but I'm sure we've birthed greater contributions to the city and the world at large. Feel free to drop ideas into the comments section if you think of anything worthy of the honour.
