Rules as of 2026-11-06
The landlord owes the tenant interest on the rent deposit every year, at the rent increase guideline in effect when the payment is due (Residential Tenancies Act, 2006, s. 106(6)). It is the same guideline table as the rent increase tool.
The landlord may keep part of that interest to top the deposit up to the most a deposit can be, the current rent for one rent period (s. 106(2) and (7)). What is kept counts as part of the deposit.
A year with no published guideline says so and computes nothing for that year.
