Alberta has no rent control
Unlike most provinces, Alberta does not cap how much rent can rise. A landlord can increase rent by any amount, as long as they follow the rules on timing and notice. The protection for tenants is not a percentage limit, it is the requirement that increases happen no more than once a year and only with proper written notice. That makes the question in Alberta less about how much and more about when, and whether the notice was valid.
How often rent can rise
Rent can be increased only once every 12 months for the same tenancy, measured from the later of the tenancy start date or the date of the last increase. During a fixed-term lease, rent cannot be increased at all unless the lease expressly says when and how it can change. Once a fixed term ends and the tenancy continues month to month, the once-a-year rule applies.
Notice depends on the tenancy type
For a periodic month-to-month tenancy, a landlord must give at least three full tenancy months written notice. For a week-to-week tenancy, the notice is at least 12 tenancy weeks. The calculator uses your tenancy type to count the notice period from today, and applies the once-a-year rule if you enter the date of the last increase, then shows the earliest the increase can lawfully take effect.
Disputing an increase
Because there is no cap, a tenant cannot dispute an Alberta increase for being too high. What can be disputed is an increase that breaks the timing or notice rules, raised more than once in a year, served without proper written notice, or imposed mid-term on a fixed lease that does not allow it. Those disputes go to the Residential Tenancy Dispute Resolution Service.
Keeping each tenancy's rent history, notices, and key dates in one place turns a disputed increase into a lookup rather than an argument. See how Habyn handles lease management and rent tracking.
