Ok thanks for the help guys! He is bringing my stuff to my place, i told him i would go to the police and when he finally saw that i'm not afraid he said he'll do what's necessary. As for the agreement it was signed and witnessed by a lawyer, a known one in Toronto. It mentions the law firm and everything with original stamps and signatures, so i don't think i can go around that. It basically stated that i'm not entitled to any spousal support, but even if i was entitled he wasn't working and i'm the one with the higher income so it's irrelevant to our case.
Like you guys said all i can do is go on welfare and bill him
