Renting in Ontario

How to rent in St. Catharines

The rules that apply to most residential tenancies in Ontario, from the province and the Landlord and Tenant Board.

  1. 1

    Set a monthly budget

    Leases in St. Catharines closed at a median of $1,875/month over the last 90 days — the table above breaks that down by bedroom count.

  2. 2

    View the unit and apply

    Landlords in Ontario may ask for rental history, credit references, a credit check and income information when you apply.

  3. 3

    Sign the Ontario Standard Lease

    Most private residential landlords must use the province's standard lease. If you ask for it in writing and don't get it within 21 days, you can withhold one month's rent.

  4. 4

    Pay only the deposits the law allows

    A rent deposit can be no more than one month's rent and can only be used for your last month. A refundable key deposit is allowed; damage and pet deposits are not.

  5. 5

    Know your notice rules

    Rent can go up once every 12 months with 90 days' written notice. To move out of a monthly tenancy you give at least 60 days' notice (Form N9) ending on the last day of a rental period.

Frequently asked questions

Renting in St. Catharines: your questions, answered

Answered with this page's lease data and Ontario's tenancy rules.

  • How many duplexes are for rent in St. Catharines right now?

    13 duplexes are listed for rent on the MLS® in St. Catharines.

  • What is the average rent in St. Catharines?

    Over the last 90 days in St. Catharines, rentals leased at a median of $1,875/month (average $1,887/month) across 16 leases.

  • How much can a landlord charge as a deposit in Ontario?

    A rent deposit can be no more than one month's rent (one week's if you pay weekly) and can only be used as rent for your last month. The landlord must pay you interest on it every year at the rent-increase guideline rate. A refundable key deposit is allowed; damage and pet deposits are not.

  • Does my landlord have to use the Ontario Standard Lease?

    Landlords of most private residential rental units must use the standard lease for new tenancies. If you ask for it in writing and don't receive it within 21 days, you can withhold one month's rent.

  • How much can rent go up in St. Catharines?

    The 2026 rent-increase guideline in Ontario is 2.1%. Rent can rise once every 12 months, with at least 90 days' written notice. Units first occupied for residential use after November 15, 2018 are exempt from the guideline, but the 12-month and 90-day rules still apply.

  • What are the N-forms a landlord can give?

    N-forms are Landlord and Tenant Board notices: N4 for unpaid rent, N12 when the landlord or a purchaser needs the unit, N13 for demolition, conversion or major repairs, and N5 for damage or interference. A notice does not end the tenancy by itself — only the Board can order an eviction, and only the Sheriff can enforce it.

  • When can my landlord enter my unit?

    With at least 24 hours' written notice, between 8 a.m. and 8 p.m., for reasons such as repairs, inspections or showing the unit to a buyer. Emergencies are the exception.

  • How do I end my lease in Ontario?

    Give your landlord at least 60 days' written notice using Form N9. The move-out date must be the last day of a rental period, or the end of your lease term if you have a fixed-term lease.
