"His bill would allow landlords to set down rules for acceptable pet behaviour and cleanliness of the rental unit - a provision he feels would appease tenants who don't want pets in their building. The bill would also allow pet owners who felt they had been discriminated against to file a complaint with the provincial residential tenancies branch."
Still as a landlord I would prefer to have pets option, to interview said pet along with its owner, and then decide if the pet were a risk to the apartment beyond normal wear and tear or might interfere with the quiet enjoyment or health of the other occupants of the building.
Not an easy question to decide but the wrong decision can result in major problems.
