Hart said that he was going to leave the WWF for the companies then biggest competitor, World Championship Wrestling (WCW) and he refused to lose the title in front of his Canadian fans to Michaels. During Survivor Series 1997 in Montreal, Quebec, a real-life screwjob took place when Shawn Michaels put Hart in Hart's own finishing move, the Sharp Shooter. Vince McMahon ordered referee Earl Hebner to call for the bell even though Hart didn't submit. This made Michaels become the WWF Champion. This incident would later become known as the Montreal Screwjob.
