This rent increase calculator follows Ontario's annual guideline under the Residential Tenancies Act, 2006.
Ontario rent increase basics
You can raise rent once every 12 months—either one year after the tenant moved in or one year after your last legal increase. The province publishes a rent increase guideline each year: it’s a percentage applied to the current monthly rent to find the maximum you can charge.
Example Current rent $1,000 × 1.9% guideline = $19 increase → new rent $1,019.
Notice and timing
You must give the tenant 90 days’ written notice before the new rent takes effect.
Example Tenant moved in Sept 1, Year 1. Earliest increase date: Sept 1, Year 2. Serve form N1 no later than June 1, Year 2 (90 days prior).
Guideline exceptions
Some units are exempt from the guideline (you can negotiate any increase). Ontario states:
"New buildings, additions to existing buildings and most new basement apartments that are occupied for the first time for residential purposes after November 15, 2018 are exempt from rent control."
If you're unsure whether your property qualifies, verify before serving notice.
