These rules are set by Ontario's Residential Tenancies Act and apply to almost every rental in Oakville.
Does my landlord have to use the Ontario Standard Lease?
Yes, for almost all private residential tenancies signed on or after April 30, 2018. The Standard Lease is a form set by the Province that sets out the rent, what is included, and both parties' responsibilities in plain language. If a landlord does not give you one within 21 days of a written request, you may be able to withhold one month's rent.
A few tenancies are exempt, including most co-op, care-home and social housing units. The guide lists them.

How much of a deposit can a landlord ask for?
At most one month's rent (or one rent period, for weekly tenancies), and it can only be used as the last month's rent, never for damage. A landlord cannot charge a separate damage deposit, a pet deposit, or interest on late rent. A key deposit is allowed but only up to the actual cost of replacing the key.
The landlord must pay you interest on the last-month's-rent deposit each year, at the rent increase guideline rate.

Who pays for utilities, and how do I know?
Whatever the lease says. Section 6 of the Standard Lease is where the landlord and tenant record who pays for electricity, heat and water, and any separate charges for parking, a locker or air conditioning. Read it before signing. If you pay your own electricity or gas, you set up those accounts yourself; who supplies each utility in Oakville is on our utilities page.
