Three provinces, three completely different answers to the same question.

You want the unit back so a family member moves in. Alberta gives you three months and no government form. BC gives you three months on a form you cannot download, because it has to be generated through a government portal. Ontario gives you sixty days on Form N12, plus one month's rent in compensation and a sworn affidavit.

Get the period wrong and the notice is void. Get the form wrong and the notice is void. Either way you restart the clock, and in BC restarting costs you another three months.

Here are the current numbers.

Alberta

Alberta has no prescribed government forms. The Ministerial Regulation includes samples, and the province's own handbook confirms they are optional. A notice you write yourself is valid, provided it contains the address, the end date, your signature and the reason.

Ending a periodic tenancy without cause is restricted to a list of allowable reasons: you or a relative moving in, a sale where the buyer or their relative will occupy, demolition, conversion to non-residential use, major renovations, or condominium conversion.

• Week to week — one full tenancy week
• Month to month — three full tenancy months
• Year to year — 90 days before the end of the tenancy year
• Major renovations — 365 days
• Condominium conversion — 365 days

A late notice does not shorten the period — it pushes the end date out. Fixed-term tenancies end on the stated date with no notice from either side, and the tenant vacates by noon.

A 14-day notice applies for substantial breach: non-payment of rent, interference with other tenants, significant damage, illegal activity, and failure to vacate at the end of a term. The end date sits at least 14 clear days after service. For non-payment, the notice must state the tenancy will not end if the tenant pays the arrears plus rent falling due by the termination date — the tenant can object in writing to most 14-day notices, but not to a non-payment notice.

A 24-hour notice applies only where someone assaulted or threatened to assault you or another tenant, or did significant damage. There's no right to object. If the tenant stays, you apply for an order within 10 days.

British Columbia

BC prescribes every form, and two of them no longer exist as PDFs.

• Unpaid rent or utilities — Form RTB-30, 10 days notice, tenant disputes within 5 days
• Cause or breach — Form RTB-33, 1 month notice, tenant disputes within 10 days
• Landlord or close family occupancy — Form RTB-32L (portal only), 3 months notice, tenant disputes within 21 days
• Purchaser occupancy — Form RTB-32P (portal only), 3 months notice, tenant disputes within 21 days
• Demolition or conversion — Form RTB-29, 4 months notice, tenant disputes within 30 days
• Caretaker or manager use — Form RTB-29C (portal only), 4 months notice, tenant disputes within 30 days

The three-month figure is the one to note. BC moved landlord's-use notices from two months to four in July 2024, then back down to three months for purchaser use in August 2024 and for landlord and close-family use in June 2025. A large share of the advice online still says four months.

Personal-use notices must be generated through the RTB portal. No downloadable PDF exists for RTB-32L, RTB-32P or RTB-29C — the portal issues a Notice ID, and a notice served on anything else is not an approved-form notice and will not get you an order of possession.

Three more BC rules with teeth

• Personal-use notices are unavailable in buildings with five or more rental units, unless the building is stratified with separate owners — small multiplex owners hit this wall hard.
• You owe the tenant one month's rent in compensation, payable on or before the effective date. The tenant is entitled to withhold the last month's rent instead.
• The stated occupant has to move in and stay at least 12 months. If they do not, the former tenant is entitled to 12 months' rent.
• Deemed acceptance is the mechanism making the notice work: if the tenant does not dispute within the deadline, they are conclusively presumed to have accepted the tenancy is ending, and you seek an order of possession by direct request with no hearing.

Ontario

Ontario prescribes forms, publishes them freely, and voids them for small errors. The N-series is the notice. The L-series is the application you file afterward.

• N4, non-payment of rent — 14 days monthly, 7 days weekly. File L1 the day after the termination date.
• N5, interference, damage, overcrowding — 20 days, voidable in 7. File L2 on or after day 8.
• N5 second notice, second within 6 months — 14 days, not voidable. File L2 the day it is given.
• N6, illegal act — 10 or 20 days. File L2 within 30 days.
• N7, wilful damage or serious safety impairment — 10 days, not voidable. File L2 within 30 days.
• N8, persistent late payment or end of term — 60 days monthly, 28 days weekly. File L2 the day it is given.
• N11, mutual agreement to end — as agreed. File L3 within 30 days.
• N12, landlord, purchaser or family own use — 60 days. File L2 plus affidavit, within 30 days.
• N13, demolition, conversion, major repairs — 120 days. File L2 within 30 days.

N12 details landlords get wrong: the notice period is 60 days and it must end on the last day of a rental period. Compensation of one month's rent is due on or before the termination date, and non-payment is a mandatory bar to eviction. An affidavit sworn by the person who intends to occupy has to accompany the L2 — a bare statement does not do it. The occupant must intend to live there at least one year, and a bad-faith notice exposes you to a T5 application worth up to 12 months' rent plus an administrative fine.

N13 compensation scales with building size: five or more units means three months' rent or another unit, fewer than five means one month's rent.

Since July 1, 2026, maximum fines under the Residential Tenancies Act doubled to $100,000 for an individual and $500,000 for a corporation, and the window to request a review of an LTB order dropped from 30 days to 15.

Ontario Bill 60 changes were scheduled for September 21, 2026: the N4 termination period dropping from 14 days to 7, N12 compensation waived where the landlord gives 120 or more days notice, and the end of automatic conversion of fixed terms to month-to-month. Confirm the commencement date before you rely on any of these.

The three mistakes costing the most time

• Serving the right form for the wrong reason — an N5 for behaviour better matched to an N7 gets dismissed, and you start over 20 days behind.
• Ending the notice mid-period — Ontario N8 and N12 notices must end on the last day of a rental period, and Alberta periodic notices run in full tenancy weeks or months. A termination date landing on the 14th of the month invalidates an otherwise perfect notice.
• Serving early and filing late — Ontario's L2 applications mostly have to be filed within 30 days of the termination date. Miss the window and the notice expires unused.

Before you serve anything

Confirm four things: the tenancy type, because periodic and fixed-term rules diverge; the rental period end date, because most notice periods key off it; the service method your province accepts and the deemed-receipt rule attached to it; and whether your reason maps to a ground the statute recognizes.

LuxOasisOS keeps the lease, the tenancy dates and the communication history for each unit in one place, so the right date is in front of you when you need it. Province-specific notice and lease templates are on our roadmap.
