What makes a rent increase notice defective?
- Less than 365 days since the tenancy started or the last increase.
- Less than 3 full tenancy months notice (90 days is not equivalent).
- Attempting to raise rent during a fixed-term lease.
- Missing required content: landlord signature, date, effective date, new rent amount.
- Served by a method not permitted by the RTA (verbal notice, text message without proper electronic authorisation).
How to challenge a defective rent increase notice
Serve a written objection on the landlord within a reasonable time, citing the specific defect (e.g., "the notice is dated May 10 and specifies July 1 effective date, which is less than 3 full tenancy months notice"). Continue paying the original rent. If the landlord proceeds to charge the increased rent, apply to RTDRS for an order and a refund of any excess collected.
What if the increase is lawful but I cannot afford it?
The tenant's options are to accept the increase, negotiate with the landlord (a smaller increase, a longer notice, or a lease renewal at the old rate), or provide notice to end the tenancy and move. In a softer 2026 rental market, many landlords will accept a smaller increase or hold flat to retain a strong tenant, so negotiation is often productive.
How much rent increase notice is required in Alberta?
For periodic (month-to-month) tenancies, at least 3 full tenancy months written notice. A tenancy month runs from the rent due date to the next rent due date. If rent is due on the first, a notice served in May with effective date September 1 is compliant (June, July, and August are the 3 full tenancy months). Fixed-term leases cannot have rent raised during the term; increases only take effect at renewal.
