When two people are trying to go through the same door at the same time
A Canadian standoff is two people going through the same door like,

*Canadian accent* "Please after you." "Oh no, no after you."

"But you've got groceries."
"I know, but it's mostly junk food so please you go."

Get the Canadian standoff mug.
When only one urinal is left in a men's lavatory, and two gentlemen want to use it, a Canadian Standoff commences. Both men whip out their shafts and beat eachother off untill one person cums. In which case the other party win the right to piss in the urinal.
GF:"what took you so long in their?"
Joey: "sorry babe I got into a Canadian Standoff, which I happily claimed victory!"
