How to Serve a Rent Increase Notice in Alberta

Writing a perfect rent increase notice means nothing if you can't prove the tenant received it through a lawful delivery method. Under Section 57 of the Residential Tenancies Act (RTA), only specific service methods count — and the burden of proving service falls entirely on the landlord.

Use the wrong method and the notice is void, even if the tenant admits they saw it.

The Three Lawful Delivery Methods

1. Personal Delivery

Hand the notice directly to the tenant. This is the simplest method and takes effect immediately upon delivery.

You can also leave the notice with another adult who resides in the tenant's unit — this counts as substituted personal service. Handing it to a visitor, neighbour, or minor does not count.

Proof: have the tenant sign a receipt acknowledging delivery, or bring a witness who can confirm the date and time of handover. A signed proof-of-service sheet is the gold standard.

2. Registered Mail

Send the notice through Canada Post via registered or certified mail. This gives you a tracking number and delivery confirmation.

Under the RTA, registered mail is deemed received seven days after the mailing date. Factor this into your notice period calculation — if you need the notice received by January 31, you must mail it no later than January 24.

Proof: keep the Canada Post registration receipt and the tracking confirmation showing delivery. These are your evidence in a dispute.

3. Electronic Service (Email or Portal)

Email delivery is permitted, but only under a specific condition: the tenant must have explicitly provided an email address or designated an electronic portal for receiving notices within the tenancy agreement.

You can't email a rent increase notice just because you have the tenant's email address. The lease must authorize electronic service.

When properly authorized, electronic delivery is deemed received 24 hours after transmission. Keep printed records of the sent email, including headers showing the timestamp, the recipient address, and any delivery receipts.

Methods That Don't Count

The following do not satisfy RTA service requirements, regardless of the circumstances:

• Sliding a notice under the door — explicitly identified by Service Alberta as invalid
• Taping it to the front door
• Sending a text message or SMS instead of the agreed email address or tenant portal
• Leaving it in the mailbox (standard mail, not registered)
• Sending it through WhatsApp, Facebook Messenger, or similar apps instead of the agreed email address or tenant portal
• Verbal notice — the RTA requires written notice delivered through a statutory method

Even if the tenant responds to a text saying "OK, I got the notice," the service itself is invalid. The tenant could later challenge it through the RTDRS, and the notice would be void.

Building a Proof-of-Service File

In a dispute, the RTDRS will ask the landlord to prove lawful service. Tenants frequently claim they never received the notice, especially when the increase is substantial. Your proof file should include:

For personal delivery:

• A dated proof-of-service sheet signed by the tenant
• Or a witness statement with the witness's name, date, and time of delivery

For registered mail:

• The Canada Post registration receipt (showing the mailing date)
• The tracking record showing delivery confirmation
• A copy of the notice as mailed

For electronic service:

• A screenshot or printout of the sent email with full headers
• The email timestamp and recipient address matching the lease
• A copy of the lease clause authorizing electronic service
• Any automated read or delivery receipt

Keep everything together in a file for the property. If you're managing multiple units, maintain a separate service record for each notice.

Timing the Service Method

Your delivery method affects when the notice is "received" for notice-period purposes:

This matters for hitting the notice-period deadline. If you need the tenant to have received the notice by January 31 and you're using registered mail, mail it by January 24 at the latest. Using email (where authorized), send it by January 30.

The Alberta Rent Increase Guide includes a complete proof-of-service log template and a service-method checklist — so you can document delivery correctly the first time and have the records ready if the increase is ever challenged.
