Eminem's October 26, 2000 concert at the SkyDome in Toronto came under a last-minute threat from political luminary Jim Flaherty, then Ontario's Attorney General. He wanted the rapper stopped at the border and forbidden from performing because of his misogynistic lyrics, arguing that he didn't want anyone who would publicly advocate violence against women allowed into the country. Liberal MPP Michael Bryant added to the pile on, suggesting that Slim Shady should be charged with hate crimes for his lyrics.
In the end, these idle threats never really grew into anything more than typical polite Canadian concern. Eminen crossed the border and the concert went off without a hitch.
