The Rent Increase Checker
Got a rent increase notice? Check it in ten seconds — the cap for your year, the dollar math on your rent, and the clock the notice has to respect. Ontario, sourced, no signup.
The guideline applies to most Ontario units. Exempt: buildings first occupied after Nov 15, 2018, long-term care homes, community housing — and the first rent agreed with a new tenant (turnover).

Notice — 90-day rule
Last increase — 12-month rule
Above-guideline increases need an LTB order (your landlord applies — Form L5), or in limited cases your written agreement (Form N10, with a 5-day cooling-off). Disputes go to the LTB (Form T1) within 12 months of first paying an improper amount. Care homes, co-ops and social housing have their own rules.
Sources & assumptions
- Guidelines, 90-day written notice on the proper form, the 12-month rule, the 2.5% cap, exemptions: ontario.ca — Residential rent increases (updated Jun 23, 2026; 2027 = 1.9%, 2026 = 2.1%).
- "Lowest in four years" context (2.1% for 2026, 2025 = 2.5%): Ontario news release (Jun 30, 2025).
- Forms + fees: LTB — Forms, filing and fees — N1/N2 notice forms, T1 ($53 / $48 via the portal), above-guideline application L5 ($233 + $10 per additional unit, max $1,000). LTB process updates Sept 21, 2026 touched termination/application forms, not N1/N2.
- The underlying statute: Residential Tenancies Act, 2006.
- Verified October 2026. Estimates, not legal advice — your lease and the LTB's rules are the final word. For a live dispute, consider duty counsel or a licensed paralegal.
