The festival debuted in 1987 and is the longest running rock show in
Canada, but took a year off last year.
It will take place at Downsview Park in Toronto and will feature performances, the Flatliners, and the Stereoghoax.
Edgefest is only the second Stone Temple Pilots show to be announced since the alt-rock band recently revealed it was reuniting. The group will also play May 17 at the Rock on the Range festival in Columbus, OH.
