Lehality of Security Camera in Shared Space Rental
I live in northern Ontario.
When I moved into my current rental in April 2025, I was robbed 2x. So I bought 3 cameras, one is the doorbell, one is in my private bedroom and nowhere she can be seen unless she walks into my room, and one is in the living room pointed directly to the front door, only showing the front door and a corner of the couch. All cameras were installed before she moved in. There is no audio recording.
My first roommate was aware of them and we both felt safer with them. She got a new job and sublet her room to a random lady who moved in October. The camera is out in the open, easily seen. She stays in her room, doesn't clean the house, does nothing but pay rent (and tick off my landlord by breaking the basic rule of not using laundry at peak times). My landlord recently found out that the roommate had sublet the room, I was under the impression he knew as I work 10 to 12hr days and my old roommate said she did it properly, he is okay as long as I am.
She has been making house decisions and I am expected to follow them, such as she has decided that I can't use the bathroom in the morning because even though I leave at 7:03 and use it to brush my teeth and pee before work, and her at 8:30, she apparently needs it the entire time.
She has also decided that the living room security camera is apparently harassment and prevents her from having privacy. Note that there is no sound, and my videos delete after 1 month unless I save them, which unless it is my cat or a theft, I genuinely don't care about it. She is threatening to call the cops on me for this, even though again it is pointed at the door and only for security due to being robbed. I feel it is necessary and that if I am robbed, she should be held accountable for any missing items. I am away to deal with my father's declining health, and she has turned the camera away. She also left my cat outside sinceI left.
As far as I am aware, a camera with no sound, pointed in a shared space, especially in its current location, is not illegal.
