Looking at Vancouver studios. Nerd Corps looks good, kinda high on the medium level. There are several Flash based studios that seem low key like Atomic Cartoons, Pork and Beans, Ooga booga. All of whom have positions for animators open (though experiences is nessessary and/or preferred.)
Mercury Filmworks looks official and they have open submissions to work for them but no specific openings aside from a graphic designer. DHX is also in Vancouver, though this one is pretty high up there and looks like experience is key.
