Renting Out a Room or Basement Suite in Canada: A Side-Income Guide

Renting out a room or a basement suite in Canada means charging someone to live in part of a home you own or have the right to offer. A room in the same household and a self-contained suite are different projects. The room can be furniture and a written agreement. The suite is zoning, a building permit, fire and building code work, and a tenancy that may be hard to end. This suits someone who can live with another person in the house and will follow the city’s rules before advertising. It is a poor fit if you need the space back next month, or if you plan to build a kitchen without a permit.

How the rent is reported, and why capital cost allowance on the house is a principal-residence decision, is basement suite rental income and taxes. A stall or a garage with no one sleeping there is parking or storage.

What is the difference between a room and a basement suite in Canada?

A room is living space inside your home, often with a shared kitchen or bathroom. A basement suite, in municipal language, is a separate dwelling: its own kitchen, bathroom, and usually its own entrance. Cities regulate the suite. Provinces regulate the tenancy. You can owe both sets of rules at once.

Short-term stays of a few nights are a third product. Toronto’s short-term rental page says you can short-term rent a secondary suite only if that suite is your principal residence, and that you may not separately short-term rent a secondary suite or laneway suite while you live in the main part of the house. This guide is about longer stays. Read the city’s short-term rules before you list nights on an app.

What do Toronto, Ottawa, and Vancouver require for a basement suite?

The three cities below publish their own suite pages. Other municipalities have their own. Confirm the city of the house, not a neighbouring one.

Toronto. The City’s secondary suite permit guide describes a building permit for an interior alteration that adds a second dwelling unit, smaller than the primary unit, in an existing detached house, semi-detached house, or townhouse. A basement apartment is the example the page uses. The permit package includes a rental renovation licence screening form when the work is a repair or renovation of a residential unit. Contact Toronto Building about the Ontario Building Code and fire rules for your floor plan. A finished basement with a hot plate is not the permit.

Ottawa. The City’s additional dwelling unit page says an additional dwelling unit is a separate dwelling in the same building as the principal home, in a detached, linked-detached, semi-detached, duplex, or townhouse. You need a building permit before you alter walls, enlarge a window, or add a door, even when the work looks small. Lots on municipal water and wastewater may have up to two additional dwellings where the rules allow: two apartments, or one apartment plus a coach house. Lots on a well or septic are limited to one additional dwelling or coach house. The new unit needs separate ground-floor access unless the building or fire code allows another arrangement.

Vancouver. The City’s create or legalize a secondary suite page says a secondary suite is an approved unit with its own kitchen and living area and a separate external entrance, inside a larger one-family or two-family dwelling. It cannot be strata-titled. A third suite is not allowed. A suite is not legal until the final inspection is passed. You need a business licence to rent the suite long term. You do not need that licence if family will live there. Unpermitted suites are not legal dwelling units and are not eligible for the city’s short- or long-term licences.

If the house is in another city, use that city’s building department. A permit issued in Ottawa does not legalize a house in Gatineau.

Which landlord-tenant rules apply when you rent a room or suite?

The statute depends on the province and, in several provinces, on whether the occupant shares a kitchen or bathroom with the owner. Read the official page before you copy a lease from the internet. This is not legal advice.

Province or territory office	Where to start	A rule that changes a room rental
Ontario	Renting in Ontario and the Residential Tenancies Act, 2006	Section 5(i) says the Act does not apply to living accommodation whose occupant must share a bathroom or kitchen with the owner, the owner’s spouse, child, or parent, or the spouse’s child or parent, when that person lives in the building. A self-contained suite is a different question. Most covered tenancies use Ontario’s standard lease.
British Columbia	Residential tenancies and the Residential Tenancy Act	Section 4(c) says the Act does not apply to living accommodation in which the tenant shares bathroom or kitchen facilities with the owner. Section 19 says a landlord must not take a security deposit or a pet damage deposit greater than the equivalent of half of one month’s rent.
Alberta	Residential tenancies and the Residential Tenancies Act	Section 2(2)(c) says the Act does not apply to rooms in the living quarters of the landlord if the landlord actually resides in those quarters.
Quebec	Being a lessor at the Tribunal administratif du logement	Quebec does not use a provincial RTA. Leases of a dwelling follow the Civil Code and TAL procedures. Read the lessor pages before you advertise a room.
Manitoba	Residential Tenancies Branch	Use the branch’s landlord materials for deposits, notices, and rent.
Saskatchewan	Office of Residential Tenancies	Confirm the current landlord guide on that site.
Nova Scotia	Residential tenancies	Confirm forms and fees on the provincial page.
New Brunswick	Residential Tenancies Tribunal	Start with the tribunal service page.
Prince Edward Island	IRAC rental	The commission publishes rental rules and forms.
Newfoundland and Labrador	Landlord and tenant	Use the provincial landlord page.

Ontario’s Act, section 105, says the only security deposit a landlord may collect is a rent deposit under section 106. Section 106 says that deposit cannot be more than the lesser of one rent period and one month’s rent. Ontario also publishes an annual rent increase guideline. Confirm the current percentage. A shared-kitchen arrangement that falls outside the Act does not become “no rules.” Contract terms and other law can still apply. Do not change the locks to force someone out.

Territories have their own housing rules. If the house is in Yukon, the Northwest Territories, or Nunavut, use that government’s landlord page rather than a southern statute.

How do you rent a room or legalize a suite in Canada?

Step 1: Choose the room or the suite on purpose

If you will share a kitchen, say so in the ad. If you want a separate suite, stop and open the city’s permit page. Building the kitchen first and “getting the permit later” is how suites fail an inspection.

Step 2: Check zoning, fire exits, and ceiling height with the city

Toronto, Ottawa, and Vancouver each say a permit is part of creating the unit. Ask about smoke alarms, egress, and parking on that lot. The Vancouver how-to materials describe minimum size and ceiling rules. Use the current guide for your city rather than a number from another municipality.

Step 3: Tell the insurer you will have a tenant

A homeowner policy written for a family may not describe a tenant. Ask for the landlord wording before anyone moves in. This is not insurance advice. A broader look at policies is side hustle insurance.

Step 4: Use the province’s forms and deposit limits

In Ontario, start with the standard lease when the Act applies, and stay inside the rent-deposit cap. In B.C., stay inside the half-month cap for a security deposit. In Quebec, use the TAL lease materials. Do not invent a “damage deposit” the statute does not allow.

Step 5: Screen and put house rules in the agreement

Quiet hours, guests, smoking, and who pays heat belong in the agreement when the law lets you set them. A rule that contradicts the tenancy statute will not help you. Keep copies with your records.

Step 6: Separate the rent from household spending

Rent that lands in the same account as groceries is hard to report. A spending account such as KOHO can hold the rent until you move the expense share. Compare fees. The tax treatment of that rent is the basement suite tax guide.

What does a year of room rent look like?

Illustrative example

Assumed numbers, not a market survey.

Suppose a furnished room with a shared kitchen rents for $700 a month and the person stays 12 months. Gross is $8,400. Suppose you spend $40 a month more on utilities because of the extra person, which is $480, and $200 on a mattress you bought for the room. Cash left before tax and before a vacancy month is $8,400 − $480 − $200 = $7,720. A legal basement suite with a permit, a new kitchen, and a month empty is a different sketch. Construction costs belong in contractor quotes, not in this paragraph. How to split a roof or a furnace on the tax return is in the tax guide, not a guess that “half the house” is always fair.

What mistakes do new room and suite landlords in Canada make?

• Renting an illegal suite. Vancouver says an unapproved suite is not a legal dwelling and is not eligible for a rental licence. Toronto and Ottawa require permits for the work that creates the unit.
• Assuming every roommate is outside the tenancy act. The exemption in Ontario and B.C. is about sharing a bathroom or kitchen with the owner who lives there. A locked basement suite is not that layout.
• Taking a damage deposit the statute does not allow. Ontario’s Act limits landlords to a rent deposit within the cap in section 106.
• Listing the suite nightly while you live upstairs. Toronto’s short-term page does not allow that split.
• Skipping the insurer. A tenant is a fact the policy should describe.

Which tax rules apply to room and suite rent in Canada?

Report the income. Renting space and providing basic services such as heat, light, parking, and laundry is usually rental income. Meals and other services can make part of it a business. The split is T2125 vs T776. Expenses, capital cost allowance, and the principal residence exemption are in basement suite rental income and taxes. Long-term residential rent and GST/HST are covered there too. This is not tax, legal, or insurance advice.

Which guides sit next to room and basement rental in Canada?

The tax page is basement suite rental income and taxes. Form choice is T2125 vs T776. Short-term rental of a place you do not live in is a different project, covered in Airbnb arbitrage red flags. City context for two tight rental markets is Toronto, Ottawa, and Vancouver. Short answers to other side-income questions are in the side hustle tax FAQ.
