I don't subscribe to the 'we invented x' thing ... it dismisses all the work of those who went before. Some of the stuff claimed as Canadian inventions in messages above is chauvanistically incorrect anyway, something we learned from Thomas Edison fans ;o)

I'll submit:

Not knowing or caring we don't know the words to the National Anthem
Greenpeace
Diana Krall, and

... Pamela Anderson. You're welcome.
