Why a Lock Change After Move-In Is Non-Negotiable
When you take possession of a property, you are trusting that the only keys in circulation are the ones handed to you at closing or by your landlord. In reality, that is rarely true. Landlords in Toronto are legally required under the Residential Tenancies Act to give tenants reasonable security, but there is no law that guarantees a fresh lock change between occupants. Previous tenants may have made duplicates at any of the dozens of key-cutting shops along Bloor Street or Danforth Avenue. Contractors who worked on the unit, housekeepers, dog walkers, or family members of the prior resident could all still have working copies — and none of those people are on your radar.
Rekeying or replacing your locks immediately eliminates that entire chain of unknown key holders. It is not about distrust toward your landlord; it is about taking control of who can access your home. For condo owners in buildings along the waterfront or in North York high-rises, this also applies to suite entry doors — building management keys are a separate matter, but your individual unit lock is entirely your responsibility to secure.
