Updated July 23, 2026. Canada's federal foreign-buyer restriction remains in effect through January 1, 2027.

Canada's restrictions on foreign purchases of residential real estate have changed how international investors approach the market.

The federal prohibition does not, however, apply to every type of multi-unit property. The legislation's definition of residential property focuses on buildings containing fewer than four dwelling units, creating a different treatment for larger multi-unit properties.

For investors interested in Toronto rental housing, that distinction makes multiplex and larger multi-unit properties particularly important to understand.

The Federal Foreign Buyer Ban

Canada's Prohibition on the Purchase of Residential Property by Non-Canadians Act restricts certain purchases of residential property by non-Canadians.

The federal restriction was introduced in 2023 and was later extended through January 1, 2027.

For purposes of the Act, the definition of residential property generally captures detached houses and similar properties containing not more than three dwelling units, as well as condominium units.

A property containing four or more dwelling units therefore falls outside that particular federal definition.

That does not mean every other tax, financing, zoning, or ownership rule disappears.

Ontario's NRST Uses a Different Threshold

Foreign investors purchasing in Ontario also need to consider the province's Non-Resident Speculation Tax.

The important point is that the federal prohibition and Ontario's NRST do not use the same unit-count threshold.

Unit CountFederal Foreign Buyer BanOntario 25% NRST
1–3 unitsGenerally within the federal residential-property definitionApplies where the statutory requirements are met
4–6 unitsOutside the federal residential-property definitionCan still apply
7+ unitsOutside the federal residential-property definitionOutside the 1–6 residence threshold

In practical terms, a fourplex or fiveplex may fall outside the federal foreign-buyer prohibition while still being subject to Ontario's NRST.

Foreign investors should therefore have the legal and tax treatment of a particular acquisition confirmed before assuming that a four-unit threshold resolves every restriction.

Why Multiplexes Matter to Foreign Investors

Properties containing four or more dwelling units can remain available to investors who would otherwise be restricted from purchasing a single-family property, condominium, duplex, or triplex under the federal Act.

Toronto's broader move toward multiplex housing has also created more interest in small multi-unit properties as a distinct real estate asset class.

1. Multiple Sources of Rental Income

A multiplex generates rental income from several units rather than relying on one tenancy.

That does not eliminate vacancy or operating risk, but it can reduce the extent to which the property's entire rental income depends on a single tenant.

2. Greater Focus on Income-Producing Real Estate

Multi-unit investment decisions are often driven more heavily by rental income, operating expenses, financing, and long-term property performance than by the resale dynamics of an individual condominium or single-family home.

That can make the category attractive to investors approaching Toronto real estate from an income-property perspective.

3. Long-Term Housing Demand

Multi-unit properties participate directly in the rental-housing market by providing several homes within one building.

Investors should still evaluate neighbourhood demand, rents, operating expenses, property condition, financing, and acquisition price rather than assuming every multiplex will produce the same return.

4. Development and Conversion Opportunities

Toronto's evolving multiplex framework has also created opportunities to add units to qualifying low-rise residential properties.

Investors considering that strategy should distinguish between purchasing an existing multi-unit property and acquiring a property that still requires planning, permitting, financing, and construction before the intended number of units can be created.

Foreign Ownership Also Creates Tax and Management Considerations

Acquiring the property is only one part of foreign real estate ownership in Canada.

Non-resident owners receiving Canadian rental income may also have withholding and tax-filing obligations.

LandLord's guide to non-resident rental-property tax explains the general framework, including the role of the NR6 process and Section 216 returns.

Owners living outside Canada also need a practical system for leasing, tenant communication, maintenance, rent collection, inspections, emergencies, and local oversight.

Those operational considerations can be just as important as the acquisition structure itself.

How Multiplex Investment Can Add Rental Housing

The federal restriction distinguishes between smaller residential properties and properties containing four or more dwelling units.

As a result, foreign capital that cannot be used to purchase certain single-family homes or condominiums may still be directed toward larger rental properties.

In some cases, that investment can support the preservation, renovation, or creation of multiple rental units rather than the acquisition of a single owner-occupied dwelling.

Conclusion

Canada's foreign-buyer restrictions did not close every path to Canadian real estate investment.

As of July 2026, properties containing four or more dwelling units fall outside the federal Act's definition of residential property, making multiplexes and larger multi-unit buildings particularly relevant to foreign buyers.

Ontario's NRST creates a separate layer of analysis, however, and its threshold is different from the federal rule.

Before acquiring a property, foreign investors should confirm the federal rules, provincial tax treatment, financing implications, ownership structure, and Canadian tax obligations that apply to the specific transaction.


Frequently Asked Questions

Can foreign investors still buy multiplex properties in Canada?

The federal foreign-buyer prohibition defines residential property in a way that generally captures properties containing not more than three dwelling units. Properties with four or more dwelling units therefore fall outside that federal definition, although other taxes and ownership rules may still apply.

Is a fourplex exempt from every foreign-buyer cost or restriction in Ontario?

No. A fourplex may fall outside the federal prohibition while still being subject to Ontario's Non-Resident Speculation Tax where the statutory requirements are met.

Why are the federal and provincial thresholds different?

They come from different legislation serving different purposes. Investors need to assess each regime independently rather than assuming that qualification under one automatically creates an exemption under the other.
