QUESTION: WTF IS THAT?

I live in southern ontario (that's in canada in case you were
wondering.....) and the last few nights I've noticed this massively
bright star relatively close to the horizon and generally
nor-north-west. I'm confused, just what in the hell is this object
and why is it so bright? (I'm thinkin' venus or something but I dont
know much about the planets and where they're supposed to be and
when...).
Any Help IDing this thing would be much appreciated!
