# KeyToRental

> The AI property agent for Ontario landlords: it fills the empty unit (listings, an AI phone line, viewings, applications), tracks the rent and prepares the Ontario forms. The landlord decides.

KeyToRental is Canadian (Ontario). Rental listings are public pages; everything else is a signed-in landlord app. Guides are general information, not legal advice.
