I"d just straight up tell her she's nuts, that you're not going to partake in some crazy bitches delusions and that the whole thing is ridiclous. The I'd tell her if she continues to harass you, that you'd be getting a restraining order and you'll be asking the landlord to have her evicted (In Ontario harassment like that is grounds for eviction).

I think it's pretty clear that she's spying on you, and I'd tell her straight up that you know that is whats going on. She's nuts, I wouldn't show hostilities but I'd as plainly as possible tell her she needs help. If your landlord won't assist you in her removal, turn to things that will really fuck her up, like printing off mental disorders that fall within the crazy shit she is doing. Keep reassuring her that she needs help in a calm friendly voice, and that you really want her to get it. I'm sure theres some mental health groups in your area, pick up group therapy pamphlets and drop them in her mailbox with little notes on how you think this will help her. If this really upsets her just leave them for when she comes over to complain.

If she does eventually go to court for it, just tell the judge that she is obviously mentally ill and you've been trying to assist her for months. Keep those pages that you printed off and present them to the judge when you do goto court, with enough sheets/pamphlets like that the judge with more than likely side with you.
