“Maximum amount a landlord can request as security deposit: Week-to-week lease — No more than one week's rent. Mobile home site lease — No more than three months' rent. All other leases — No more than one month's rent. If the tenant pays all or some of the security deposit to the landlord, the landlord must complete and deliver a Security Deposit Remittance Form, along with the money, to the Residential Tenancies Tribunal within 15 days of receiving the money from the tenant. Failure to do so is an Offence under the Act.”

This is not legal advice
Kaza applies published provincial tenancy rules and shows the source it used, and it refuses to answer when a rule is unverified or overdue for review rather than guessing. It does not know the facts of your tenancy, any order made about it, or any agreement between the parties. For advice on a specific situation, speak to the tenancy regulator for the province or to a lawyer.
These same rules are enforced inside the product: Kaza refuses to raise an unlawful charge or serve an unlawful notice, rather than warning about one. How the compliance engine works.
