The Residential Tenancy Branch (RTB) has a Compliance and Enforcement Unit (CEU) that can intervene in situations involving serious and repeated non-compliance of the Residential Tenancy Act and/or dispute resolution orders. The CEU has the authority to conduct investigations, issue official warnings and, if necessary, levy administrative penalties of up to $5,000 per day.
Almost all applications submitted to the RTB are adjudicated through the normal dispute resolution process, so you should only make a complaint to the CEU when faced with urgent situations involving egregious landlord behaviour. For example, if your landlord has changed the locks and/or thrown your possessions on the street, the CEU might be able to provide assistance.
