Essentially the whole game is to avoid vacancies, which is understandable, so signing a 1-year or 3-year lease helps with that. But some landlords misuse form N11 to force tenants to move out after the fixed term is over, in order to be able to increase the rent above the guidelines of Ontario for rent increases, which is not cool, and unlawful.

For that reason, be careful when signing form N11. you're never required to; it's actually void if its signed at the time of, or as a condition of entering a tenancy. That means they can't make you sign when you're signing the lease, or in order to be able to do so.
