The act of defecating on one's head. Mainly guy-to-girl defecation, but can also be done the other way.
Dude 1: "Last night was fuckin sick."
Dude 2: "How so?"
Dude 1: "After I fucked that one chick, she let me give her a Canadian top hat."

A day of celebration in Canada honouring Celine Dion. Traditionally the celebrations are started by Wayne Gretzky taking a diarrhea poo into Celine Dions mouth while she attemps to sing the Canadian national anthem. At noon on this great day rabid tequila fed Bears, Cougars, Moose, and Beavers are then set loose by the thousands in downtown Toronto to rape, kill, and eat whatever they please. Celebrations are concluded by Avril Lavigne finger banging a Canadian Goose to orgasm while Wayne Gretzky in turn fornicates her with a golden jewel encrusted hockey stick.
"Dude did you watch Canadian History? The viscosity of Wayne Gretzky's diarhea poo this year was amazing!"

Using an ice cream cone as protection during sex. Usually done with ice cream still in the cone and ice cream stuffed in the vagina, as is done with the Canadian Fridge.
Black Dude - My lady complained when I used a pointy cone as a Canadian Condom, but she didn't wanna get pregnant, so...
White Guy - Man! That must have hurt.
Black Dude - Yeah, that pointy tip didn't give me enough head space. I'll have to use a cylindrical cone next time.

A sex move
When a corn cob is shoved into the vaginal pipe and left to marinate overnight. It is then removed and fried in a pan, leaving a crispy brown coating from the caramelised juices. You then get the corn cob whilst hot, and give it a fresh dip into the pipe, covering it in the special sauce and burning the chick at the same time

"So they want to play a round robin match?"
"Yeah, but they're too retarded to know how to do it themselves so we have to officiate."
"Oh, CANADIAN round robin."

When a woman is being fucked in the piledriver position. The the man ejaculates and pools his cum in the crevice of her ass and pussy.
The man then allows the cums to drip down onto the face and mouth of the woman that is below. This is a Canadian piledriver waterfall.
