Well, they're not
exclusive to Canada, but there are quite a few
Canadian Inventions... Like the
washing machine, the
zipper, the
paint roller,
kerosene...
And the ones most people know about.
Insulin,
Pablum, the
snowmobile,
Superman, the
Telephone, and
Trivial Pursuit.
The Tuck-Away-Handle
beer carton is worth mentioning, too.
