What Is a Security Deposit?

A security deposit is an amount of money a tenant pays up front to protect the landlord if something goes wrong.

The idea is that if the tenant causes damage beyond normal wear and tear, breaks something and refuses to pay, or leaves owing money, the landlord can keep some or all of the deposit to cover the loss.

In many markets, people also talk about deposits in pet situations. For example, a tenant with a large dog may offer a deposit to reassure the landlord and increase their chances of being accepted. That is the practical goal of the deposit, it is meant to reduce the landlord’s risk.

What a security deposit is meant to cover

A security deposit is usually intended to cover things like

Damage beyond normal wear and tear
Repair or replacement costs when the tenant is responsible
Unpaid amounts that are hard to collect after the tenant leaves

It is basically a financial cushion.

The Quebec reality deposits are generally not allowed in residential leases

In Quebec, residential leasing is strict on this.

The Civil Code of Québec says a landlord may not demand any amount of money other than rent, in the form of a deposit or otherwise. It also says the landlord may not demand postdated cheques.

In plain language, that means a landlord cannot require a security deposit, a damage deposit, a key deposit, or a pet deposit as a condition of renting a residential unit. The Tribunal administratif du logement and public guidance regularly repeat this principle.

The Government of Quebec has also published a reminder that demanding a security deposit is illegal and ties it directly to article 1904.

The grey area when a tenant offers voluntarily

People often ask about the exception.

Some professional organizations explain that even though a landlord cannot require a deposit, a tenant can choose to offer one voluntarily in very specific conditions, for their own reasons. The key is that it must not be required and must not be presented in a way that makes the tenant fear they will be rejected if they say no.

A simple rule keeps it clean

If the tenant cannot freely say no, then it is not truly voluntary.
