A residential tenancy ends at the end of the term, which is typically the end of any month. That means that tenants must vacate the unit no later than11:59 pm on the last day of the month. This could present problems for tenants who are moving into a new unit on the 1st day of the following month as they may have to store their belongings overnight and stay with friends or at a hotel while they move.
This can also cause problems when a buyer is purchasing a home occupied by a tenant on the last day of the month, as the buyer will expect to get the keys late in the afternoon and yet they may not be able to access the home until late that night if the tenant has not yet vacated. This could result in extra moving costs which the buyer could claim from the seller, since vacant possession was not given in time.
It is preferable to make arrangements in advance with your tenants so that moves can be accommodated for everyone's benefit. The key is proper preparation in advance, and not waiting until the last minute.
