When I was younger I gravitated towards their real early stuff, but as I've gotten older the later stuff definitely appeals to me more (though Less Talk, More Rock is still probably the album I will listen to most).
On the topic of Canadian hardcore, any Toronto area Pals ever go to Faith/Void? It's one of the coolest record stores I've been to. Full of crazy obscure DIY stuff, along with some more "notable" bands mixed in.
