How deposit interest works in Quebec

  • Article 1904 of the Civil Code of Quebec says a landlord may not demand any amount other than rent, in the form of a deposit or otherwise.
  • That means no security deposit, damage deposit or last month's rent deposit, and no deposit interest.
  • Questions about rent and leases in Quebec go to the Tribunal administratif du logement.

Frequently Asked Questions

Common questions from Canadian landlords and tenants about deposit interest

Quebec Deposit Interest Questions

No. The Civil Code of Quebec (article 1904) does not allow a landlord to demand any amount other than rent, including a security or damage deposit.

In most provinces and territories, yes. The province sets the rate each year and the landlord owes that interest to the tenant. Quebec does not allow security deposits at all, in New Brunswick the deposit is held by the province and the interest goes to the Crown. Ontario does not allow damage deposits, but landlords must pay interest on a last month's rent deposit.

Multiply the deposit by the annual rate, then by the share of the year the deposit was held. When a deposit is held across several years, each year uses its own rate. Some provinces compound, so interest earned in earlier years also earns interest. This calculator handles both and shows the breakdown for each period.
