Club Rockit (or The Rockit) was a real punk venue in Toronto, on Church Street in the Weston neighborhood. Bryan Lee O'Malley has called it "cramped, ugly and terrible"  and it closed down sometime in 2005.
The Rockit also appears in Scott Pilgrim Vs. the World, where Scott also fights Matthew Patel. The label when Scott entered Club Rockit said that the place was a toilet.
