Serving a notice in Ontario: methods, deemed receipt, and proof

Landlords spend their attention on picking the right form and almost none on delivering it. That's backwards. Choosing between an N5 and an N7 is a judgment call you can get advice on. Service is a set of mechanical rules, and mechanical rules are the ones that quietly produce defective notices: a notice served a day short, or served by a method that adds five days nobody counted, or served perfectly with no way to prove it.
Deemed receipt: the date that actually matters
A notice is not effective when you send it. It is effective when the rules say the tenant received it, and that date depends on how you sent it. Every downstream date (the cure window, the termination date, your filing deadline) counts from deemed receipt, not from the day you hit send.
- Handing it to the tenant in person: same day.
- Email, where it's properly available to you: same day.
- Leaving it in the mailbox or where mail is ordinarily delivered: same day.
- Regular mail: deemed received five days after mailing, under s.191 of the Act.
- Courier: deemed received the day after it was given to the courier.
The five-day mail rule is the one that catches people. If you need a tenant to receive an N4 by a particular date and you're mailing it, you're posting it five days earlier than you think. And if the deemed date lands on a weekend, expect it to roll forward to the next business day rather than working in your favour.
Email needs the tenant's written consent
Email is fast, cheap, and same-day for deemed receipt, which makes it the obvious choice and the one most often used improperly. Under the Board's Rules of Procedure, serving documents by email requires the recipient's written consent, given in advance. Having their email address is not consent. Having previously emailed them about a repair is not consent.
That consent is also revocable in writing. A tenant who consented last year can withdraw it, and once they have, email is no longer a valid method for them. If you rely on email service, keep the consent on file and check it's still live before you send anything that matters.
Getting the proof right
Valid service you cannot prove is, at a hearing, indistinguishable from no service at all. The Certificate of Service is the document that closes that gap: it records what was served, on whom, by which method, on what date, and by whom. It's what you file alongside your application.
Whatever you use to produce it, the underlying record needs to answer these without you reconstructing anything:
- Which document was served: the form, and ideally the exact version that went out.
- Who it was served on. Every tenant on the lease, individually.
- The method, precisely. 'Mailed' and 'couriered' produce different deemed dates.
- The date it was served, and the resulting deemed-receipt date.
- Who served it.
Keep the artifacts that back it up too: the sent email, the courier tracking, a photograph of the addressed envelope. They cost nothing to retain and they're the difference between an assertion and a record.
Serve every tenant
On a multi-tenant lease each tenant is a party. Serving one and assuming they'll tell the others is a routine and avoidable defect. Serve them all, and record each service separately.
The common failures
- Counting the notice period from the send date instead of deemed receipt.
- Mailing without adding the five days.
- Emailing without consent on file, or with consent that has since been withdrawn.
- Serving only the tenant you deal with, on a lease with several names on it.
- Serving the notice properly and keeping no record of having done it.
- Serving a notice with the wrong termination date on it. On an N12 or N13 the date must land on the last day of a rental period, and service can't fix a date that was wrong on the form.
Service rules and the Board's Rules of Procedure do change, and this is a summary rather than legal advice. For a notice you expect to be contested, have a paralegal confirm both the notice and the service before you rely on them.

When is a mailed notice considered received in Ontario?
Five days after mailing, under s.191 of the Residential Tenancies Act. The notice period runs from that deemed date, not from the day you posted it, so a mailed notice needs to go out five days earlier than the same notice delivered by hand.
Can I serve a notice by text message?
No. Text messaging is not a permitted method of service for Landlord and Tenant Board documents. Use one of the permitted methods and keep the proof. A text is fine as a courtesy heads-up alongside proper service.
Do I need the tenant's consent to serve by email?
Yes, written consent given in advance, under the Board's Rules of Procedure. It can be withdrawn in writing at any time. Simply having the tenant's email address does not amount to consent.
What if the tenant refuses to accept the notice?
You do not need them to accept it. Use a permitted method, such as leaving it where mail is ordinarily delivered, then record what you did and keep the proof. Deemed receipt does not depend on the tenant acknowledging anything.
Let the dates compute themselves
Kera applies the deemed-receipt rule for the method you served by, writes the deadlines onto the notice, and produces the Certificate of Service automatically.
