Can a landlord increase rent during a fixed-term lease?

In most cases in Ontario a landlord cannot increase the rent during a fixed-term lease unless the lease itself specifically allows a mid-term increase and both parties agreed to that clause in writing. If the lease does not permit an increase, the rent stays the same until the fixed term ends. The province's rules are set out in the Residential Tenancies Act ^[1], and disputes are handled by the Landlord and Tenant Board ^[2].

When can rent be increased legally?

Outside a fixed-term lease, landlords may increase rent but must follow the rules: provide proper written notice and respect the province's timing and guideline limits. Typically a landlord can increase rent only once every 12 months and must give at least 90 days' written notice before the new rent takes effect. For rent increases above the guideline or for special circumstances, landlords may need to apply to the Landlord and Tenant Board. See official guidance and required documents for specifics ^[2].

How to review a rent increase notice

• Check the notice for the date the landlord served it and the effective date of the increase, and confirm the 90-day requirement and 12-month rule.
• Compare the notice to your lease to see whether the agreement allows mid-term increases or contains a negotiated clause.
• Calculate the new monthly amount and whether it follows provincial guidelines or appears to exceed them.

What forms and official steps are involved?

Tenants and landlords should rely on official guidance and forms from the Landlord and Tenant Board and Ontario government pages. There is no special universal provincial printed form needed to give a rent increase notice beyond a written notice that meets the legal content requirements, but the LTB provides application forms if you need to challenge an increase or apply for relief ^[2]. If a landlord seeks an above-guideline increase, they must apply to the Board with supporting documents.

Practical steps for tenants faced with a mid-lease increase

1. Read the written notice carefully for deadlines and required information.
2. Review your lease to see if it allows the specific increase.
3. Note any deadlines to respond or to apply to the Board; meeting timelines keeps your rights intact.
4. Contact the landlord calmly to ask for clarification and to request the reason and documentation for the increase.
5. If needed, prepare an application to the Landlord and Tenant Board and assemble supporting records like the lease, notices, and receipts.
6. Consider your options, including negotiating, staying until the lease ends, or planning a move if an agreement cannot be reached.

When to contact the Landlord and Tenant Board

Contact the Landlord and Tenant Board if you believe a rent increase is illegal, if the landlord did not give proper written notice, or if the increase is above the allowable guideline without Board approval. The Board can hear disputes and issue orders. You may also use forms and guidance on the Board site to file an application and learn about schedules and hearing procedures ^[2].

Moving and housing search options
