Not a huge punk fan, liked Pennywise back in the day, one of my fav bands during high school was this local punk band from North Van, called DBS. They have since broke up, but I loved their music back in the day.
Hard for me to name just a few... Some of these may not be considered punk bands and I'll try not to name too many that have already been listed in other posts,
Strung out
No use for a name
Social distortion
tiger army
legendary shack shakers
lawrence arms
The Sainte Catherines (my personal fav)
PROPAGANDHI
death by stereo
88 fingers louie
black halos
street dogs
THE DWARVES
Flogging Molly
IGNITE (their last album was great.. Called out darkest days)
snfu
snuff
The Supersuckers
Swingin Utters
THE DRAFT
The Matadors
I also really love Chuck Ragan's new stuff, he is one of the former singers of hot water music (who are now the draft). His solo stuff is mostly folk/country/accoustic but it is very very good.
