Answer
Toronto hosted WrestleMania VI, where the Ultimate Warrior defeated Hulk Hogan to win the WWF Championship. The event took place on April 1, 1990, at the SkyDome, and marked a significant moment in wrestling history. Warrior's victory was a major upset, as Hogan had been the dominant force in the WWF for several years. The match was highly anticipated and drew a record-breaking crowd of over 67,000 fans.
