Canada Condo Assignment Sales: Rules and Tax in 2027

An assignment sale transfers the rights and obligations of a purchase and sale agreement from the original buyer (the "assignor") to a new buyer (the "assignee") before the original transaction closes. In the pre-construction condo context, the assignor purchased a unit from a developer with occupancy 2–5 years away. Rather than wait for closing, the assignor sells their contractual position — typically for a profit if the condo has appreciated during construction. The assignee takes over the original contract and pays the difference between the original purchase price and the new agreed assignment price. The developer must typically consent; many builder contracts restrict or charge fees for assignments. Assignments are common in Toronto, Vancouver, and Calgary where pre-construction premiums can be substantial. See the Canada condo mortgage guide for related financing details. The CRA real property GST/HST guide covers tax obligations.

HST/GST treatment of assignment sales depends on the assignor's status: (1) Individuals assigning for the first time (not in the business of selling): The assignment profit is generally not subject to HST if the original intent was owner-occupation — but the CRA scrutinizes this heavily; (2) Investors / serial assignors: If the CRA determines the original purchase was made as an investment (not personal use), HST applies to the full assignment price (not just profit); (3) The "new housing rebate" complication: If the original buyer claimed or intended to claim a new housing HST rebate, assigning before occupancy may void the rebate — requiring repayment; (4) Assignee GST/HST: The assignee takes over the original contract — new construction HST obligations apply at closing. Since August 2022, the federal government made HST applicable to most assignment sales of new residential properties to reduce speculative activity.

This is the critical tax question for assignors. The CRA determines treatment based on the original intent: (1) Business income (fully taxable): If the CRA concludes the purchase was made with the intention to profit (flip), the entire profit is business income — taxed at marginal rates (up to 53% in some provinces). Factors: short holding period, multiple prior flips, financing with intent to assign, no occupancy planned; (2) Capital gains (50% inclusion rate): If the original purchase was genuinely intended as a personal residence or long-term investment, profit is a capital gain — 50% is included in income. The 2024 federal budget proposed increasing the capital gains inclusion rate to 2/3 for gains above $250,000; verify current rules with a tax professional; (3) Principal residence exemption: Generally does NOT apply to assignment sales because the unit was never occupied. Always consult a tax advisor before assigning. External reference: CRA — Tax treatment of real estate sales.

Financing an assignment purchase is more complex than a standard resale or new-build purchase: (1) Most major banks do not finance assignments: CIBC, TD, RBC, BMO, and Scotiabank generally decline or require the property to be at occupancy/closing stage before issuing a mortgage commitment; (2) Alternative lenders and credit unions: Some credit unions and B-lenders will finance assignments, typically requiring 20–25% down payment; (3) Assignment-specific financing: Some mortgage brokers specialize in arranging bridge financing or private mortgages to cover the gap between assignment price and developer mortgage takeover at final closing; (4) Builder incentive mortgages: If the builder offers capped-rate mortgages, the assignee may be able to assume this financing — verify with the developer; (5) CMHC insurance: CMHC-insured financing is generally not available for pure assignment transactions. Work with a broker experienced in pre-construction. See how to use a mortgage broker.

Assignment purchases carry risks beyond a standard resale: (1) Price risk: You are buying based on a floor plan; if the market declines before occupancy, you could close at a price above market value; (2) Delay risk: Construction delays are common (1–3 year delays are not unusual) — your closing and financing plans must accommodate this; (3) Developer consent fees: Many builders charge $1,000–$10,000+ assignment consent fees, reducing the assignor's profit and raising the assignee's cost; (4) Unknown final specs: The unit may differ slightly from contract specs due to permitted builder substitutions; (5) Limited legal protection: Provincial condo acts (Ontario's Condo Act, BC's Strata Property Act) offer less protection for assignment buyers than resale buyers — no standard rescission period applies in most provinces; (6) Tarion / home warranty: Assignment does not reset the Tarion warranty clock in Ontario — the assignee inherits the original warranty terms.

Several major changes took effect after 2022: (1) Federal HST on assignments (August 2022): The Department of Finance Canada made HST applicable to assignment sales of new or substantially renovated residential properties — previously many assignments were treated as exempt. This significantly raised the tax cost of assignment flips; (2) Ontario's "10-day cooling-off period" (2023): Bill 91 in Ontario extended rescission rights for pre-construction condo and freehold purchases — assignees in Ontario may benefit from this period; (3) Underused Housing Tax (UHT): Foreign owners of vacant properties face a 1% annual tax — relevant for non-resident assignors; (4) Anti-flipping rules (2023): Profits on residential properties sold within 12 months of purchase are deemed business income (fully taxable) under the federal anti-flipping rule — this applies to assignments too; (5) Lender tightening: Following the 2022 rate shock and condo value corrections in some markets, many A-lenders further restricted assignment financing.
