An assignment sale happens when the original purchaser of a pre-construction unit sells their Agreement of Purchase and Sale to a new buyer before the building closes — before they ever take possession. The new buyer steps into the original contract: same purchase price, same deposit structure, same closing date. It’s one of the least understood corners of the Ontario pre-construction market, and right now it’s also one of the most active.

Why Sellers Assign Instead of Just Closing

Most assignors are not investors who changed their mind about real estate — they’re people whose life circumstances changed since they signed, sometimes years earlier. The most common reasons we see: a job relocation, a change in family situation, or a financing gap between what they qualified for when they signed in 2021 or 2022 and what they qualify for today under current stress-test rules and rates. Rather than risk not closing, a motivated assignor sells the contract instead.

This is exactly why 2026 has produced an unusually active assignment market: a large wave of 2021–2022 VIP purchases are reaching their closing dates now, and a meaningful share of those buyers are choosing to assign rather than close.

What Buyers Actually Gain

For a buyer, an assignment can offer real advantages over both a fresh pre-construction purchase and a resale purchase:

  • — Locked-in pricing from an earlier market cycle, sometimes meaningfully below what the same unit would cost at today’s builder pricing
  • — A motivated seller with a real deadline, which creates genuine negotiating room that a builder rarely offers
  • — The ability to see the actual finished unit, or a very close model, instead of buying entirely from renderings
  • — A closing date that’s often close, which can suit buyers who don’t want to wait years for occupancy

The Process: Builder Consent Is the First Gate

Every assignment requires the builder’s written consent — this is written into the original Agreement of Purchase and Sale, and builders control the process closely. Typical steps: the assignor submits an assignment request to the builder (often with a fee), the builder reviews and approves the new buyer, a separate Assignment Agreement is drafted between assignor and assignee, and both the original APS and the assignment agreement close simultaneously at final closing. Some builders restrict assignments until a certain construction milestone, or only permit them through an approved list of realtors — which is exactly why working with a team that has active builder relationships matters for a smooth assignment.

What an Assignment Actually Costs

Buyers evaluating an assignment need to underwrite more than just the “assignment price” quoted by the seller:

  • — The original purchase price plus any profit premium the assignor is asking for on top
  • — Assignment fee charged by the builder, which varies by project and is usually paid by the assignor but sometimes negotiated between parties
  • — HST treatment, which can differ from a standard resale — this needs to be confirmed with a real estate lawyer and accountant on a deal-by-deal basis
  • — Land transfer tax, which is calculated at final closing based on the total consideration, not just the assignment price paid to the seller

Risks Worth Understanding Before You Buy

Assignments are not risk-free. Buyers should confirm the building’s construction timeline and any reported delays, review the builder’s Tarion warranty standing, and get independent legal review of both the original APS and the assignment agreement before signing anything. A deal that looks like a great price on paper isn’t a good deal if the closing timeline or building status doesn’t match what was represented.

Why This Matters for Sellers Too

If you purchased pre-construction in 2021 or 2022 and your circumstances have changed since, assigning can let you capture the appreciation that’s built into your contract without ever closing on the unit yourself — often faster and with less complexity than most people expect.
