What is it?

A condominium (condo) is a way of owning property, not a type of building. The land and building are divided into "units" and "common elements". Each owner owns their unit alone, and all owners own the common elements together. High-rise towers are the best-known example, but townhouse complexes, low-rise buildings and even vacant land can be registered as condos.

In Ontario, the Condominium Act, 1998 sets the rules for creating and running a condo. When you buy a condo you get more than a home: you get a share of the common elements, a duty to pay your share of the costs, a duty to follow the rules, and the right to take part in how it is run.

What is yours and what is shared

Section 11 of the Condominium Act sets out who owns what. Where your unit ends is different in every condo, so check the declaration and the description (the plan).

PartWhat it isWho owns it
UnitThe space shown as a unit on the plan, with the structures and fixtures inside itThe owner alone (exclusive ownership and use)
Common elementsEverything except the units: lobby, hallways, elevators, garage, outer walls, roof, pipes, amenitiesAll owners together (as tenants in common). Each owner’s share is set in the declaration
Exclusive use common elementsCommon elements used by one unit only, such as a balcony, terrace or patioOwned by everyone, used by that unit only. Repair duties depend on the declaration

A unit and its share of the common elements cannot be sold separately (s. 11 (4)). Your balcony is usually an exclusive use common element, not part of your unit.

The condo corporation and the board

The moment the developer registers the declaration and description, the land is divided into units and common elements and a condominium corporation is created (s. 2 (3)). The corporation’s job is to manage the property and assets on behalf of the owners (s. 17).

The corporation is run by a board of directors (at least three people) elected by the owners (s. 27). The board sets the budget, collects fees, hires the management company and makes rules. Day-to-day work is usually done by a condo manager. Since November 1, 2017, condo managers and management companies must be licensed by the CMRAO (Condominium Management Regulatory Authority of Ontario).

Three documents govern the condo: the declaration (the condo’s constitution: unit boundaries, each unit’s share and fee percentage, use restrictions), the by-laws (how the board is formed and operates) and the rules (daily-life rules on pets, noise, parking and so on). Rules must be reasonable and consistent with the Act, the declaration and the by-laws (s. 58). Owners, tenants and the board must all comply with them (s. 119).

Types of condos

The Act divides condos into freehold (the owners together own the land) and leasehold (the land is leased, and owners hold a leasehold interest in their unit and common elements). Freehold condos come in four types.

TypeWhat it is
Standard condominiumThe most common type in Ontario. Has units and common elements such as a lobby, outer walls and amenities
Phased condominiumA standard condo built in phases. New units and common elements are added to the first corporation; the final phase must be registered within 10 years of the first registration
Vacant land condominiumUnits are often vacant lots when you buy, and the layout looks like a subdivision. Common elements are things like private roads, sewers and a park
Common elements condominiumNo units, only common elements. Each owner’s own lot (a parcel of tied land, POTL) carries a share of common elements such as shared roads or a golf course

The Act has different requirements for each type. Check the declaration and the status certificate to see which type you are buying.

Money: fees, the reserve fund and special assessments

Owners pay the common expenses (condo fees) in the proportions set in the declaration (s. 84). You must pay even if you never use the amenities or are in a dispute with the corporation. Part of every fee goes into the reserve fund, the savings for major repairs.

If the budget falls short, the board can levy a special assessment without the owners’ consent. If you do not pay fees or assessments, the corporation gets a lien on your unit and can enforce it like a mortgage (s. 85). See "Condo fees", "Reserve fund" and "Special assessment" for details.

How is it different from a freehold home?

CondoFreehold home
What you ownYour unit plus a share of the common elementsThe land and the whole building
Major repairs (roof, walls, boiler)The corporation, from the reserve fund. Costs are shared through feesYou, with your own money
Monthly costsMortgage + property tax + condo feesMortgage + property tax (no condo fees)
Living rulesDeclaration, by-laws and rules (can limit pets, short-term rentals, renovations)Only municipal by-laws and zoning
Who decidesThe board and owners’ meetingsYou
Documents when buyingStatus certificate (disclosure statement for pre-construction)Survey, title search, home inspection
DisputesCondo disputes go online to the Condominium Authority Tribunal (CAT)Court, or directly with neighbours

Some townhouses are condos and some are freehold. Check whether a listing says "condo townhouse" or "freehold townhouse".

Who oversees condos?

  • The Condominium Authority of Ontario (CAO): the body designated under the Act. It provides information on owners’ rights and duties, mandatory training for directors, a database of condo corporations (the Condo Registry) and a dispute resolution system.
  • The Condominium Authority Tribunal (CAT): an online tribunal for disputes about records, noise, odours, light, vibration, smoke, pets, and vehicles, parking and storage. It costs $25 to file, $50 for Stage 2 mediation and $125 for Stage 3 adjudication, $200 in total. You do not need a lawyer to apply.
  • The CMRAO: licenses and disciplines condo managers and management companies. Complaints about a manager go here.
  • New condos: Tarion (new home warranty and deposit protection) and the HCRA (builder licensing) are also involved. See "Tarion" and "HCRA".

What to check before you buy

  1. Resale condo: make your offer conditional on reviewing the status certificate, and go through the declaration, by-laws and rules, the budget, the reserve fund and the building’s age, the fees, any lawsuits and the amenities with your lawyer. Make sure the rules fit your plans (pets, renting out, short-term rentals).
  2. Pre-construction condo: you receive the builder’s purchase agreement, the disclosure statement, the condominium addendum, the HCRA information sheet, the Tarion warranty information sheet and the CAO’s Condo Buyers’ Guide. You have a cooling-off period of 10 calendar days to cancel for any reason. It starts once you have received all three of these: the purchase agreement signed by you and the builder, the disclosure statement and the Condo Buyers’ Guide. Your written notice must reach the builder (or its lawyer) within those 10 days. See "Cooling-off period" and "Disclosure statement".
  3. Either way, have a lawyer who knows condos review the documents, look the builder up in the HCRA’s Ontario Builder Directory, and look the corporation up in the CAO’s Condo Registry.

Common questions

Is my balcony part of my unit?

Usually not. Balconies, terraces and patios are normally "exclusive use common elements": the corporation owns them, and only your unit may use them. Who repairs things like the glass railing is set out in the declaration. Check the declaration and description for your exact unit boundaries.

What is the difference between a condo and an apartment?

A condo is a form of ownership; "apartment" usually describes a building type or a rental home. In the same tower, if each home is owned separately it is a condo; if one company owns the whole building and rents it out, it is a rental apartment. When an owner rents out a condo unit, the tenant must follow the condo’s rules and Ontario’s Residential Tenancies Act.

Can a townhouse be a condo?

Yes. A townhouse registered as units plus common elements (roads, lawns, visitor parking) is a condo and has fees. A townhouse where you own the land outright is freehold. There is also the POTL type, where you own your lot but a private road is a common elements condo.

Can I pay less if I never use the amenities?

No. Section 84 (3) of the Act says you must still pay your share even if you give up the right to use the common elements, cannot use part of them, or are in a dispute with the corporation.

Can the condo rules on pets or short-term rentals change?

The board can make and change rules, but they must be reasonable and consistent with the Act, the declaration and the by-laws. Restrictions written in the declaration are much harder to change. Before you buy, check the declaration, by-laws and rules that come with the status certificate against your plans.

Where do I complain about a noisy neighbour or parking?

Start with the manager and the board. If that fails, you can apply online to the Condominium Authority Tribunal (CAT). It handles noise, odours, pets, parking and records disputes, and the fees for all three stages total $200.
