Eh, when I think of Canada.... this is first in my mind (after Rush, Gordon Lightfoot, and Capt. Kirk...)
A look at Canadian actors, musicians, and entertainers . . .
METAL CHURCH 's debut album has always rocked me.
I think some of Zeppelin songs are "Metal"... ie, the title track from TSRTS is pretty wicked.
I'll also mention Filter and Dream Theater.
