Neuraxis - The Thin Line Between is phenomenal though, so much more mature than their older stuff. As for lacking aggression, listen to "Dreaming the End", sounds a lot like songs off The Negation (probably one of the most aggressive albums out there).
I hate neuraxis' drummer though.......he always looks like he's in unbearable pain....and he's a terrible drummer live.
Martyr, Goreguts, and old Cryptopsy are still some of my favorite all time/Canadian bands. SYL is pretty good too, but mostly because I love Hoglan. You get the odd local band like Deamon, Mayhem Inc., and Dead of Winter that are good but yeah.....we lack the richness and diversity of europe.
