While I agree the stata’s fine is not legal, I do not agree that imposing a fine is a form of bullying. As the secretary of a large strata for many years, the law is woefully inadequate in this area. Building management and volunteer committee members spend a significant amount of time dealing with a small minority of residents, typically tenants, who consider that they are not required to comply with bylaws. This is time we should be spending on productive works. Making life uncomfortable for a tennant who considers themselves somehow exempt from bylaws is often a a more productive use of our time.
If a tennant stops paying rent for whatever reason, evict them and get a tennant who pays their rent.
