First and foremost, the most important thing for you right now is getting yourself safe. Your husband sounds incredibly abusive - physically, emotionally and sexually. As someone else suggested, look into a women's shelter and, if you feel it's safe for you to do so, get the police involved. Once you're safe, I think you absolutely need to inform CIC about this. If I understand correctly, you're applying inland which will mean you will have a landing interview where both you and your husband will need to be present. Not only would this require you staying with him until the decision is made, but you'd also be committing immigration fraud to get your permanent residence, as others have mentioned. You can still stay on your work permit until it expires, and use that time to figure out how to keep your status in Canada. I would try and seek out some legal guidance from an immigration specialist regarding your options, but I really want you to prioritise getting yourself out of what sounds like a dangerous and abusive situation. Good luck and be safe.
