From http://dc.wikia.com/wiki/Justice_League_of_America_Vol_1_75:
Originally it was meant to be that the Black Canary that was featured in this issue of Justice League was the golden age character and not her daughter. However this was retconned when the writers considered the characters physical age if she were still active at the time. As such in Justice League of America #219 it was ret-conned that the Black Canary that ended up on Earth-One was really the second Black Canary, implanted with her mother's memories until the truth was revealed later. This has since been rendered apocryphal due to the fact that changes to continuity created by Crisis on Infinite Earths have made it so that Black Canary II was a founding member of the Justice League of America instead of Wonder Woman.
