Synopsis: Canadians were asked to compare the BlackBerry with the electric oven, life saving Insulin with artery clogging poutine, the caulking gun with the Wonderbra and vote on the Greatest Canadian Invention of all time. The results are revealed in this breezy, entertaining look at which inventions Canadians consider to be the finest our country has ever produced. Picks and pans from renowned Canadians are featured while the countdown - from #50 to #1 - is presented. Hosted by Bob McDonald of CBC Radio's popular Quirks & Quarks
