What to Expect When Your Lawyer Reviews Your APS

Why you need a specialist, not just any lawyer

Any licensed Ontario lawyer can technically review a real estate agreement. But pre-construction purchase agreements are not standard OREA (Ontario Real Estate Association) resale forms — they are custom documents drafted by the builder's legal team to reflect the builder's standard terms, and can run 50 to 80 pages or more including schedules and the Tarion Addendum.

A lawyer who primarily handles wills, corporate law, or even straightforward resale transactions may not be familiar with the specific clauses that matter in pre-construction: Tarion delay provisions, development charge caps, HST elections, assignment rights, or the interplay between the APS and the condominium disclosure statement. The cost of using an under-qualified reviewer is not the lawyer's fee — it's the terms you didn't catch or negotiate.

Ask specifically: "How many pre-construction APS reviews have you done in the past year?" A lawyer who regularly reviews these agreements will have a clear, structured process and will know what amendments are typically negotiable with which builders.

The 10-day cooling-off period — your review window

Ontario law gives you a 10-calendar-day rescission period after receiving both the signed APS and the condominium disclosure statement. (For freehold pre-construction, the right is slightly different — your lawyer will clarify.) This 10-day period is your window to review, negotiate amendments, and decide whether to proceed.

Book your lawyer before you sign, not after. The 10 days disappear faster than they seem — weekends and holidays count — and a thorough review of a lengthy agreement takes time. Many experienced pre-construction lawyers recommend booking the review appointment for within 24–48 hours of signing so the full 10 days are available for negotiation.

The 10-day window moves faster than it seems — weekends and holidays count. Book early and use the full time available.

Key clauses your lawyer will review

A thorough APS review for a pre-construction purchase covers many provisions. These are among the most consequential:

• HST clause: Confirms whether the purchase price is "HST included" (with the rebate assigned to the builder) or "plus HST." Misunderstanding this clause has cost buyers tens of thousands of dollars at closing. Your eligibility for the rebate must be confirmed.
• Development charge cap: Builders pass development charges levied by the municipality through to the buyer at closing. Some agreements cap this amount; many do not. An uncapped development charge clause can add $30,000–$80,000+ to your closing costs — an amount set by the municipality years after you sign, not by the builder.
• Assignment clause: Whether you can assign the agreement to another buyer before closing, on what conditions, and at what cost. See the assignment guide for full details.
• Delay provisions and outside date: How the builder can extend your occupancy date, how many times, and what the outside occupancy date is. Your lawyer will confirm the date and explain your options if it passes.
• Mutual release conditions: The circumstances under which the builder can cancel the agreement and return your deposits. Builders typically have broader cancellation rights than buyers — understanding these conditions is important.
• Décor selection terms: The process, timeline, and any credit applied at the design centre. Confirms that any upgrade credits verbally promised are documented in the agreement.
• Tarion warranty registration: Confirmation that the home will be registered with Tarion and that the standard Tarion Addendum is included. This is mandatory for all new Ontario homes — but worth verifying and understanding.
• Unit specifications: Suite size, layout, floor, exposure, parking, locker, and any specific representations from the sales process. Confirm that everything promised is in writing.

What amendments are actually negotiable

Builders vary significantly in how flexible they are. Some major builders operate on essentially standard form agreements and will not modify them. Others — particularly smaller or newer projects with lower sales volumes — are more willing to negotiate. The state of the market also matters: a hot pre-sale with a waitlist gives buyers less leverage than a project in the later stages of selling where the builder is motivated.

Common amendments that builders sometimes accept include: a cap on development charges, improved assignment rights (or assignment permitted without consent), a cap on the number of delay extensions, and explicit confirmation of parking and locker assignments in the agreement rather than left to the builder's discretion. Your lawyer will know which requests are standard in the current market and which are likely to be rejected.

Even if the builder refuses all amendments, the review is still valuable — you leave with a clear understanding of what you're committing to, and an informed decision is always better than a blind one.

Questions to ask your lawyer

Go into the review with a prepared list. These are the questions most buyers wish they had asked:

• What is my outside occupancy date, and what are my options if it passes?
• What is my total exposure to development charges at closing, and is there a cap?
• Is the purchase price HST-included, and do I qualify for the rebate?
• What happens to my deposits if the builder cancels?
• Can I assign this agreement? What will it cost and what conditions apply?
• Are my parking spot and locker confirmed in writing, or are they assigned later?
• What are the most important things I should know going into this purchase that I probably don't?

What APS review typically costs

A pre-construction APS review in Ontario typically costs between $1,000 and $2,500 for the initial review and advice, depending on the complexity of the agreement, the number of amendments requested, and the lawyer's experience level. This is separate from the closing legal fees (which typically run $1,500–$3,000 for the closing itself, charged years later).

Do not shop for the cheapest APS review. The cost of a thorough review by a specialist is typically recovered many times over by the value of a single amendment negotiated — one development charge cap, for instance, can save $20,000–$50,000 at closing. The $1,500–$2,000 spent on a proper review is among the best investments in the entire transaction.

Some lawyers offer a flat fee for pre-construction APS review including a set number of amendment requests. Ask upfront whether the quoted fee is all-in or whether amendment negotiations are billed separately.
