How we check the rules

RentRules turns each province's tenancy rules into calculators you can run with your own dates. Every answer comes from the province's official sources: the rent increase guideline, the tenancy act, and the board's own forms and instructions.

Where the rules come from

How dates are counted

A notice counts from the day it's legally given, not the day it's written. Mailing adds 5 days in both provinces. In BC, attaching a notice to the door or leaving it in the mailbox adds 3 days. In Ontario, a courier adds one business day, and notices can't be posted on the door. Where a notice has to end on the last day of a rental period, we roll the date forward to the day before rent is due.

We test our calculators against the boards' own worked examples. For instance, the Landlord and Tenant Board's N12 instructions say a notice handed over on August 1 can end the tenancy on September 30 at the earliest, or October 31 if it's mailed. Ours gives the same dates.

When the rules change

Rules were last checked on October 8, 2026. We re-check every province when it announces next year's rent increase limit, and whenever a law changes, such as Ontario's changes of September 21, 2026.

Not legal advice

RentRules gives general information. It doesn't know every detail of your tenancy. If your situation is unusual, or a hearing is coming up, talk to the board, a tenant or landlord association, or a licensed paralegal or lawyer.
