* Landlords can ask tenants to provide:

Reference or guarantor: Landlords have the right to ask tenants to provide reference contact information, such as the tenant's previous landlord, or the tenant's employer or friend;

Proof of salary: recent paystub, employment letter, bank statements with regular salary deposit;

Prepaid cheque: Some provinces allow landlords to collect prepaid cheques from tenants (for example, tenants can sign cheques for March and April and give them to landlords in February, but this rule is not allowed in Quebec).

* Landlords cannot ask:

Landlords cannot keep tenants' income tax information, but landlords can ask tenants to show T4 as proof of income, but must return it to tenants immediately after review;

Landlords cannot increase rent beyond the amount allowed by law;

Landlords cannot ask for rent increases multiple times within 12 months;

Landlords cannot increase rent directly without notifying tenants. Landlords must send a "rent increase notice" to tenants three months in advance in accordance with provincial rental laws. Tenants cannot object to the rent increase unless it exceeds the statutory rent increase limit.
