The standard notice a landlord must serve to raise the rent on a unit covered by the rent-increase guideline.
The current rules
At least 90 days' written notice before the increase takes effect.
At least 12 months since the last increase or the start of the tenancy.
The increase is capped at the guideline — 2.1% for 2026 — unless the LTB has approved an above-guideline increase (AGI).
The effective date must fall on the rent-period anniversary.
What voids it
Serving fewer than 90 days ahead — the increase is unenforceable and the cycle is lost.
Exceeding the guideline without an AGI order.
Wrong tenant names or unit address.
