Deemed Service Dates for Rent Increase Notices in Newfoundland
The most common reason rent increase notices fail in Newfoundland and Labrador is not the form itself — it is the date arithmetic. Landlords count six months from the day they mailed the notice, not from the day the law says the tenant received it. That gap voids the increase.
What "Deemed Service" Means
Under Section 35 of the Residential Tenancies Act, 2018, a notice is not considered received on the day you send it. The statute assigns a "deemed service date" based on how you delivered the form — and your six-month notice period starts from that date, not from the postmark or the send button.
The Deemed Service Rules by Method
| Delivery method | Deemed received |
|---|---|
| Personal hand delivery | Same day |
| Delivery to co-occupant (16+) | Same day |
| Conspicuous posting | Same day |
| Mailbox or under the door | Same day |
| Registered mail / express post | 5th calendar day after mailing |
| Courier | Section 35 does not assign a fifth-day deemed-service date |
| Electronic delivery before 4:00 PM | Same day |
| Electronic delivery after 4:00 PM | Next day that is not a weekend or statutory holiday |
The five-day rule applies to registered mail and express post, not courier service. The after-4:00-PM email rule uses the next day that is not a weekend or statutory holiday.
A Worked Example: Registered Mail
You fill out Form RT-2018-00050 on October 25 and mail it by registered post the same day. Deemed receipt: October 30 (five calendar days later).
Six full months from October 30 lands on April 30. Since the increase must take effect on the first day of a rental period, and your tenant pays rent on the 1st, the earliest effective date is May 1.
If you had assumed the notice was received on October 25 (the mailing date), you might have calculated an April 1 effective date. That would leave the tenant with only five months and five days of notice — insufficient under the Act.

A Worked Example: Late Email
You email the completed form to your tenant on Friday at 5:15 PM. Because it was sent after 4:00 PM, deemed receipt moves to the next business day: Monday. If Monday is a provincial holiday, receipt moves to Tuesday.
That two-to-three-day shift can matter when you are working backward from a specific effective date.
Why Proof of Service Matters
Deemed service establishes when the clock starts. But in a dispute, you also need to prove the notice was delivered at all. For registered mail, keep the tracking receipt and delivery confirmation. For hand delivery, have the tenant sign a copy or bring a witness. For email, save the sent message with timestamps.
The Residential Tenancies Section will not accept your word alone. If the tenant says they never received the notice and you have no documentation, the adjudicator has nothing to work with.
Counting Backward From Your Target Date
The safest approach is to work backward:
- Choose your target effective date (must be the 1st of a month for monthly tenants)
- Subtract six full calendar months to get the latest acceptable deemed service date
- Subtract the deemed service offset for your delivery method (five days for registered mail, zero for hand delivery)
- That gives you the latest date you can mail or deliver the notice
Build in a buffer. A one-day miscalculation costs you an entire month.
