Canada? Aw, quit yer complainin', I'm in northern Norway, I have to wait at least a year to get new comics, and then I have to pay double the price for it, and I like it!
Another vote for Invincible from me, great series. Also another vote for both Astonishing X-Men (damn those pages had better be true... that spread page left me grinning like an idiot for hours! that said I think I saw that scene once on Buffy...) and JSA, best team books currently published.
Hearing good things about Ultimate Spiderman, about to check it out. You might want to concider trying both Ultimate X-Men and the Ultimates, not to mention the great Ultimate Fantastic Four.
Gotham Central; sort of like NYPD in Gotham, about regular cops trying to survive encounters against Arkham's finest before the Bat gets to them. Could possibly turn into The Shield in Gotham soon, with the return of Harvey Bullock...
She-Hulk; suprisingly brilliant. Comedy and superheroics side by side beautifully, it as much makes a parody out of the Marvel universe as it worships it.
And aside from that there's just about anything out there with the name Alan Moore on it...
