Back in the 1980's, the Black Canary patrolled Gotham City. The leather- and fishnet-clad vigilante prowled the city on a motorcycle, solving crimes that were too esoteric for the GCPD and busting up criminals the hard way.
Around 2010, after an absence of 20 years or so, the Black Canary has returned to Gotham. Same look, newer bike, same attitude. And she doesn't look like she's aged a day. While the Canary works primarily in Gotham, she's also been known to help out up and down the Eastern Seaboard.
For those who pay attention to such things, it isn't too difficult to work out that Black Canary's activities are pretty central to a certain part of Gotham City.
