Canadian backbreaker rack

 is a type of Backbreaker.

Description
An attacking wrestler first lifts an opponent up so the opponent's back is resting on the wrestler's shoulder, with the opponent's head pointing in the direction that the wrestler is facing. While being held face up across the wrestler's shoulder, the wrestler then links his/her arms around the opponent's torso and presses down, squeezing the opponent's spine against the wrestler's shoulder.

The Canadian backbreaker drop variation of this move sees the attacking wrestler, who is applying the hold, drop down to a kneeling position while maintaining the hold, thus jarring the back of the opponent by driving the opponent's spine into the attacking wrestler's shoulder.
