only real option I can think of would be house shows. A lot of the collective houses used the have to odd punk/hardcore show. the Vernon is the best place I can think of for punk, but if you aren't 21 that kills that idea.

also take all of this with a grain of salt, as my days of going to every show in the city are a couple years behind me so the entire scene could have completely imploded for all I know, but I doubt it
