Month-to-Month Lease Termination in Newfoundland: Notice Period and Process

The Three-Month Rule

Under Section 18(2)(b) of the Residential Tenancies Act, 2018, a landlord ending a month-to-month tenancy in Newfoundland and Labrador must give at least three months' notice. The notice must be on Form RT-2018-00039 (Landlord's Notice to Terminate — Standard).

Three months is the minimum. There is no shorter notice for personal use, property sale, or renovation — NL does not have those accelerated grounds. For standard no-cause termination, three months is the only timeline.

The Rental Period Alignment Trap

This is where landlords make the most costly mistake. A Section 18 notice must be given no later than the first day of a rental period, and the termination date must fall on the last day of a full rental period. For most month-to-month tenancies where rent is due on the 1st, that means the last day of a calendar month.

Here's the practical impact. If rent is due on the 1st and you miss October 1, the next valid date to give notice is November 1:

• The first full rental period is November 1–30
• Three full rental periods are November, December, and January
• The earliest valid move-out date is January 31

Serving the same notice on September 30 would yield a December 31 termination date — a full month earlier, because the notice arrives before the October rental period begins.

The takeaway: a notice served after the first day of a rental period does not meet Section 18(9)(b). If you miss that date, give notice by the first day of the next rental period.

Counting "Clear Days" vs. Calendar Months

For day-based cause notices under Sections 19, 22, and 24, the Residential Tenancies Office's instructions exclude the day of service and the move-out day. Section 20 is measured against rental periods, and Section 21 permits immediate notice only when the tenant's action or failure to act makes the premises unfit for habitation. Section 18 standard notice is measured in rental periods, not calendar days.

The distinction matters when your deemed service date falls close to the start of a rental period. If you mail the notice by registered post on September 26, it's deemed served on October 1 (five days later). That meets the first-day deadline, so the three full rental periods are October, November, and December and the earliest termination date is December 31.

But if you mail it on September 27, deemed service is October 2 — after the first-day deadline. Give a new notice no later than November 1; the three full rental periods are November, December, and January, and the earliest termination date is January 31.

What About the Tenant's Notice?

For comparison, a tenant ending a month-to-month tenancy gives just one month's notice under Section 18(1)(b). The asymmetry is built into the Act — landlord notice periods are significantly longer to protect tenants from displacement.

When Three Months Isn't Enough Time

If you need vacant possession sooner, the only route is a mutual written agreement under Section 18(5). The tenant must agree voluntarily. Negotiating a reasonable incentive — covering moving costs, waiving a month of rent — is common, but the tenant is under no obligation to accept.
