On the 8th day of Christmas
Canada gave to me
Real smart inventors
Artistic creators
Writers a-writing
High sugar treats
Athletic stars
Far northern sites
And a nation, bounded by seas.

Real Smart Inventors

So many to choose from.  Here are a few:

AVRO Arrow replica at Canadian Museum of Science and Technology
AVRO Arrow
Patent application for Jolly Jumper
Jolly Jumper
Photo/graphic of paint roller paraphernalia
Paint rollers
Robertson screwdrivers

And, of course, there’s Pablum, the BlackBerry, Alexander Graham Bell, the snowmobile, the guy who invented the plastic garbage bag . .  .
