Turning an existing apartment building into individually owned condominium units is a common strategy for investors, but it's a far more involved legal process than simply relisting each unit for sale. Ontario's condominium system was built around creating new condos, and layering it onto a building full of existing tenants adds a second set of legal obligations that most conversions have to navigate carefully.
Converting a rental building into condos in Ontario means satisfying the Condominium Act, 1998's registration requirements for creating a new condominium corporation, while also respecting the rights of any tenants already living in the building when the conversion begins.
Here's what the process generally involves, in roughly the order it unfolds.
Step 1: Confirm the Building Can Be Converted
Before anything else, an owner needs to confirm the property is a candidate for condominium conversion at all. This includes:
- Zoning and municipal planning approvals that permit the building's use and, where relevant, any changes needed to support individual unit ownership.
- A review of the building's physical condition — condominium status is a legal structure, not a substitute for addressing outstanding building deficiencies.
- An assessment of existing tenancies, since occupied units carry legal protections that a vacant building does not.
Step 2: Prepare the Condominium Documents
Creating a condominium corporation under the Condominium Act, 1998 requires preparing and registering a specific set of documents, generally including:
- A description — the surveyed plan showing the units and common elements.
- A declaration — the condominium's foundational document, setting out each unit's proportionate share of common expenses and the rules governing the corporation.
- Supporting professional work, including surveys and engineering or reserve fund input, to support the declaration and description.
Step 3: Address Existing Tenants
This is where converting an already-occupied rental building differs sharply from building a new condo from the ground up. Tenants living in the building at the time of conversion generally retain protections under Ontario's residential tenancy framework, and conversions can trigger specific notice obligations beyond what applies to an ordinary sale of a tenanted property.
- [ ] Confirm what notice obligations apply to existing tenants before the conversion proceeds.
- [ ] Understand that a conversion does not simply erase an existing tenancy — tenant protections under Ontario law continue to apply.
- [ ] Get legal advice on how the conversion process interacts with any tenant's existing lease before finalizing a conversion timeline.
Because these rules are detailed and fact-specific, and can vary depending on the tenancy's history and the municipality's own requirements, this step is not one to plan around assumptions — a lawyer experienced in both real estate and landlord-tenant law should confirm the requirements that apply to your specific building.
Step 4: Register the Condominium
Once the documents are prepared and any approvals obtained, the declaration and description are registered against the property, formally creating the condominium corporation. From that point forward, the building is legally structured as a condominium — individual units can be conveyed separately, each with its own share of the common elements and its own obligations to the new corporation.
Step 5: Transition to Ongoing Condo Governance
After registration, the condominium corporation takes on all the responsibilities of any other Ontario condo corporation — budgets, common expense collection, a board of directors, and, once enough units have sold, a turnover meeting transferring control from the original owner to the elected owner-board. Unsold units continue to be owned by the original owner in the meantime, functioning much like any other condo unit owner under the corporation's declaration and rules.
Common Pitfalls Owners Underestimate
| Pitfall | Why it matters |
|---|---|
| Treating tenant notice as a formality | Tenant protections under Ontario law are substantive, not procedural box-checking, and getting this wrong can delay or derail a conversion |
| Assuming the building's physical condition doesn't matter | Deficiencies discovered after registration become the new condo corporation's — and eventually the unit owners' — problem |
| Underestimating professional and municipal approval time | Surveys, engineering reports, and municipal sign-off all take real time to coordinate |
Frequently asked questions
Can a landlord simply evict tenants to convert a building to condos?
No. Existing tenants have protections under Ontario's residential tenancy laws that continue to apply during a conversion, and a conversion is not, on its own, a basis to remove a tenant outside the normal rules that govern any tenancy. Specific requirements should be confirmed with a lawyer before any notice is given.
How long does a condo conversion typically take?
It varies significantly based on the building, its tenancies, and the municipal approvals involved — there's no fixed timeline, and owners should plan for the process to take longer than a straightforward resale transaction.
Does the building need renovations before it can be converted?
Not necessarily as a legal requirement, but unresolved deficiencies become the new condominium corporation's responsibility after registration, so many owners address major issues beforehand rather than passing them along.
Who prepares the declaration and description?
These are prepared by professionals — typically a lawyer for the declaration and a licensed surveyor for the description — often working alongside engineering or reserve fund consultants depending on the building.
