Preview: a lawyer has not yet verified every rule behind this tool. ## The law behind it - N8, N12, N13: earliest termination date at the end of a period (unverified): The code adds the minimum days to the day the notice counts as given (N8: 28 days in a daily or weekly tenancy and 60 days otherwise; N12: 60 days; N13: 120 days) and then takes the first day on or after that date that is the last day of a rental period. A period ends the day before rent is next due: for weekly tenancies the day before the rent weekday, for monthly tenancies the day before the rent day (rent days 1 to 28 only), for yearly tenancies the day before the anniversary of a period start. For a fixed term the only valid date is the last day of the term; if it is too early the code gives no date. The L2 can be filed as soon as the notice is served, and no later than 30 days after the termination date. - Residential Tenancies Act, 2006, s. 58: https://www.ontario.ca/laws/statute/06r17 - Residential Tenancies Act, 2006, s. 44: https://www.ontario.ca/laws/statute/06r17 - Residential Tenancies Act, 2006, s. 48: https://www.ontario.ca/laws/statute/06r17 - Residential Tenancies Act, 2006, s. 49: https://www.ontario.ca/laws/statute/06r17 - Residential Tenancies Act, 2006, s. 50: https://www.ontario.ca/laws/statute/06r17 - Residential Tenancies Act, 2006, s. 71: https://www.ontario.ca/laws/statute/06r17 - Residential Tenancies Act, 2006, s. 69: https://www.ontario.ca/laws/statute/06r17 - Legislation Act, 2006, s. 89: https://www.ontario.ca/laws/statute/06l21 - N12: compensation of one month’s rent (unverified): For an N12 for the landlord's or a family member's own use (s. 48), the landlord owes one month's rent or another acceptable unit, unless the notice is given on or after September 21, 2026, gives at least 120 days, and ends on the last day of a period or the end of the term.

Handed to the person or to an apparently adult person in the unit, left in the mailbox or where mail is usually delivered, slid under the door or through the mail slot, faxed, or emailed: the same day. Mailed by Canada Post (including registered mail) or sent by Xpresspost: the fifth day after mailing; the code never uses an earlier delivery date. Given to a courier: the next day, or if that day is a holiday, the next day that is not. For the courier rule the code treats as holidays every Saturday and Sunday, the holidays in s. 88 of the Legislation Act, 2006 with its substitution rules, the Civic Holiday, September 30, and the next weekday after any of these that falls on a weekend; a longer list can only make the date later.
