Rules and sources

Rules as of 2026-11-10

Residential Tenancies Act, 2006: at least 12 months since the last increase (s. 119) and 90 days' written notice on the N1 (s. 116); the increase no more than the guideline for the year it takes effect (s. 120), unless the unit was first occupied after 15 November 2018 (s. 6.1). Mailed notice counts from the fifth day (s. 191(3)).

A landlord can apply to the Landlord and Tenant Board for an increase above the guideline. This tool does not cover that.

This is general information, not legal or tax advice. For your situation, check with the Landlord and Tenant Board.

This tool is also on MCP. Connect an agent to house.health/mcp and it can run this with no account.
