"We asked Canadians to help determine which inventions they considered to be the greatest that our country has ever produced. Celebrity commentators ... team up with host Bob McDonald and take us on an irreverent search for the greatest Canadian invention. Will it be the life saving insulin or the artery clogging poutine? the Blackberry versus the Wonderbra? Follow along as we feature the picks and pans of our celebrity commentators - all culminating in the final coast-to-coast vote that will reveal the illustrious title of the greatest Canadian invention." -- case.
