If you did not include the possibility of installing cameras in common areas in your lease agreement, or if you do not have a written lease agreement, then the answer is no. You will only be able to install video surveillance cameras if you get the written consent of everyone who lives in the property and uses the kitchen and common areas. To install cameras without consent would be contrary to both the Residential Tenancies Act and the Personal Information Protection and Electronic Documents Act.

If everyone agrees to installing the cameras, then this agreement should be in writing, since it is a fundamental change to the original situation that did not include cameras.

Otherwise, you will have to rely on witnesses who live in the property for your evidence regarding who is stealing food, causing damage, and so on.
