2 Chainz was scheduled to hit the stage for Drake's OVO Fest out in Toronto, but was unable to attend as planned due to extenuating circumstances.  Chainz took to his Twitter to apologize to Drizzy and his fans, explaining that he was held up and forced to endure "over exaggerated harassment," most likely at the border due to his past criminal record.

Check out his tweet above explaining the situation.  Maybe he'll be able to make up for that missed performance in the future.
