I am a canadian and have had many japanese students here studying english or on a work permit live with me. what is the question here? I can't seem to find what is being asked about a rental situation. If I could find it I could answer question for you. I can tell you though that in BC and share an apartment with someone, you are a roommate with no rights. It does not matter where you are you from. The only way you would have any legal rights is if your name was on the tenancy agreement also. If it is not then you are not covered by the tenancy act. Any problems you could sue the person through bc small claims court. Hope that helps.
