It was a chance encounter. Yorfido was with his mother picking up supplies, and Tyler was there to pick up a back brace, Yorfido's mother Diane told CTV News.
Yorfido was excited, but managed to compose himself.
"I just (stood) there for a second and I said, 'Steven Tyler?' He turned around, came to see me and gave me a big hug," Yorfido told CTV News.
After the hug ended, he told Tyler that he wanted to see him in concert, but that he couldn't get a ticket.
Tyler told his biggest fan that he'd make it happen.
And he did.
Yorfido got to see the sold-out show and had backstage passes. But the biggest thrill for Yorfido was being called up on stage to play maracas during "Sweet Emotion."
