Direct answer

Alberta has no legislated rent increase cap — landlords may increase rent by any amount. However, rent can only be increased once every 365 days, and the landlord must give at least 3 full tenancy months' written notice for month-to-month tenancies (12 weeks for weekly). An extremely large increase may be challenged as an 'economic eviction' through the RTDRS.

Methodology

The 365-day eligibility date is calculated from the later of the tenancy start date or the date the last rent increase took effect.
The earliest notice date is calculated by subtracting 3 full calendar months from the desired effective date.
The tool flags increases above 10% of current rent as a potential 'economic eviction' risk — this is an informational threshold, not a legal limit.
Fixed-term tenancies cannot have mid-term rent increases unless the agreement contains a specific rent-increase clause.
