Scarborough’s multi-unit residential market — duplexes, triplexes, fourplexes and small apartment buildings — has remained a preferred entry point for investor buyers in the GTA. Pricing per door consistently runs below comparable acquisitions in central Toronto, and rent rolls in established Scarborough neighbourhoods such as Birchcliff, Oakridge and Eglinton East have supported positive cash flow even at 2024 interest rate levels.
The legal framework for multi-unit purchases is fundamentally different from single-family or condominium acquisitions. Existing tenancies bind the buyer. Fire code compliance affects insurance and financing. The HST analysis is more involved. A buyer who proceeds with single-family expectations encounters problems at closing or in the first year.
Existing Tenancies and the Residential Tenancies Act
The Residential Tenancies Act protects tenants from termination merely because the property has been sold. A new owner inherits existing tenancies on the same terms — same rent, same lease, same notice rights — unless one of the limited statutory grounds for termination applies.
The most relevant ground for a buyer of a Scarborough multi-unit is purchaser’s own use, but the ground only allows termination of one unit, requires good-faith intent to occupy, and entitles the tenant to one month’s compensation plus notice of 60 days. A buyer acquiring a fourplex with the intent to renovate and re-rent cannot use this ground to clear the building. Bad-faith N12 notices have produced damages awards exceeding $35,000 at the Landlord and Tenant Board since 2022.
The lawyer reviews the rent roll, identifies the legal status of each tenancy, and confirms the buyer’s plan against what the Act permits before the agreement becomes firm.
Rent Roll Audit and Above-Guideline Rent
An investor pays a price that reflects the rent roll. The lawyer reviews the rent roll, confirms the rents against the lease documents, and identifies any rent in excess of the lawful rent under the Act. Rent increases in Ontario follow an annual guideline — 2.5 percent for 2024 and 2025 — with above-guideline increases requiring Landlord and Tenant Board approval in defined circumstances.
A rent that has been informally increased above the guideline is unlawful, and a tenant can apply for a rebate going back 12 months. The legal exposure transfers to the new owner. Where the rent roll shows informal increases, the buyer’s lawyer flags the issue and the deal is repriced or the agreement amended.
Fire Code Compliance and Retrofit
The Ontario Fire Code imposes specific requirements on buildings containing two or more residential units. Smoke alarms, carbon monoxide detectors, fire separation between units, second egress windows, electrical service capacity and exit signage all factor into compliance. The Toronto Fire Services inspects multi-unit buildings on complaint and on retrofit application.
Older Scarborough triplexes and fourplexes — many of them converted from single-family homes in the 1970s and 1980s — frequently fall short of current fire code requirements. A buyer acquiring such a building inherits the compliance obligation. Insurance carriers increasingly require fire code retrofit certificates as a coverage condition. Lenders may require the same.
The lawyer obtains the fire code compliance status from the city, identifies any open orders, and structures the agreement to allocate the retrofit obligation. Where significant retrofit is required, holdbacks at closing fund the work.
HST on Multi-Unit Purchases
Resale residential multi-unit properties in Ontario are generally exempt from HST under the Excise Tax Act, where the property has been used as residential rental by the seller. The exemption is not automatic. Properties that have been substantially renovated, properties that have been used for short-term rental, and properties with mixed use — a residential unit above a commercial storefront — all require careful HST analysis.
Where the seller is HST-registered and the property has been part of a commercial rental enterprise, the transaction may be subject to HST on a self-assessment basis where the buyer is also registered. Multi-unit purchases involving five or more units are subject to particular scrutiny under the rebate rules. The lawyer reviews the seller’s HST history, the buyer’s registration, and the agreement structure to ensure the HST treatment is documented correctly.
Lender Treatment of Multi-Unit Properties
Lenders categorize multi-unit residential differently than single-family. Properties with one to four units typically qualify for residential mortgage products, with the borrower assessed on personal income plus a discounted share of rental income. Properties with five or more units fall into commercial multi-residential — different lenders, different products, different underwriting and personal guarantee requirements.
Several major lenders cap the number of investment properties a single borrower can hold. New CMHC and OSFI guidance issued in 2024 has tightened qualification on rental income for properties acquired after a specified date. The lawyer coordinates with the borrower’s mortgage broker to confirm the lender’s program and to identify potential funding gaps before the agreement is firm.
Title Structure and Liability Considerations
Multi-unit investors in Scarborough commonly take title in a holding corporation rather than personally. A holding company offers liability protection — limiting tenant claims, premises liability and contractor disputes to the corporation’s assets — but typically loses access to the principal residence exemption and complicates financing. Most residential lenders do not lend to corporations on standard residential terms.
A trust structure offers a different combination of liability and tax characteristics. The decision is made before the agreement is signed. Title cannot be retroactively restructured without triggering land transfer tax on the second transaction. The lawyer coordinates with the buyer’s accountant to register title in the structure that fits the investment plan.
Working With a Scarborough Real Estate Lawyer
Mayo Law represents multi-unit property purchasers across Scarborough, including duplex acquisitions in Birchcliff and Cliffside, triplex and fourplex purchases in Oakridge, Eglinton East and the Scarborough Junction area, and small apartment building deals along Lawrence and Kingston Road. The firm reviews rent rolls, audits tenancy compliance under the Residential Tenancies Act, confirms fire code retrofit status, structures HST treatment and registers title in the corporate or trust structure the investor selects.
A multi-unit purchase is a long-term holding with multi-tenant exposure. Investors who engage a Scarborough real estate lawyer before signing the agreement build the right structure into the deal. Investors who sign first generally inherit problems that are difficult to unwind.
