Rent Increase Rules
Check a rent increase against Ontario's rules — the 2026 guideline, the 90-day notice, the once-a-year limit — and who helps for free if it breaks them.
Rent in Greater Sudbury has climbed fast — the average is around $1,873 a month, up 5.7% in a year, with a 1.6% vacancy rate that leaves tenants little room to move. The rules on how much your rent can go up, and how much notice you must get, are set by Ontario. This checks an increase against those rules and does the arithmetic for you. The one that catches people: rent control only caps homes first lived in on or before 15 November 2018. Most newer buildings, additions and many newer basement apartments are exempt, so there's no limit on the amount — only on the notice and timing. The checker asks which applies to you. Your landlord must give at least 90 days' written notice on the official form (the N1), and can only raise the rent once every 12 months. (The check below counts the 90 days as three months.)
