I have been facing trouble with an intruder in our apartment. I noticed that we have a more relaxed approach to the security system. I feel insecure and threatened here. So I'm planning to make the security services more responsible. I have heard about various firms providing security services in Ontario. Can I make use of these services to handle the intruder on my property? What are the various services I can adapt to handle intruders? Please share your thoughts and suggestions on it.
