I have another Canadianism for you.... Rummoli
http://en.wikipedia.org/wiki/Rummoli
Yesterday I spent the afternoon playing Rummoli with my sister. My grandmother introduced me to the game. I never visited her without my allowance money.
Who knew it was Canadian?

Although the link doesn't indicate it, I am certain that it was devised by grandmothers for swindling money out of their grandchildren.
