When engaged in the coital act, the man spreads maple syrup all over his partner but leaves her back covered, then rolls her into missionary position. After finishing, the woman should be stuck to the bed (and more importantly, horrified and flailing while trying to escape). Thus, a Canadian Trap Door.

"My parents told me I was conceived whilst performing the Canadian Trap Door for the Yukon Pornography Club."
