Critical Dates, Delays, and Tarion's Outside Occupancy Date

Tentative vs. firm occupancy dates

Your purchase agreement includes an occupancy date — the date by which the builder expects your unit to be ready for you to take possession. In Ontario, this date goes through two stages: tentative and firm.

The tentative occupancy dateis the builder's initial projection at the time of signing. It is not binding. Builders are permitted to change the tentative date by providing the buyer with advance notice — typically 90 days under the Tarion addendum.

The firm occupancy dateis a commitment. Once the builder sets a firm date, they can only move it under specific circumstances, with proper notice, and subject to Tarion's rules. The firm date is normally set when the builder is confident that construction will be complete within 120 days.

Under the Tarion Addendum (the standardized schedule that must be included in all new home purchase agreements in Ontario), the builder must give notice of any change to the firm date at least 65 days before that date. This notice requirement is strictly enforced. Shorter notice means the builder may owe you compensation.

How many times can a builder delay

There is no fixed limit on the number of times a builder can move a tentative or firm date — but the total delay is capped by Tarion's outside occupancy date rule.

Under the Tarion framework, the outside occupancy date is the absolute latest date by which the builder must give you possession. This date is calculated based on the original tentative occupancy date in your agreement. Tarion's standard rules permit the outside date to be no later than:

• For condominiums: 24 months after the original tentative occupancy date
• For freehold homes: typically framed as a defined outside closing date, also subject to a cap

In practice, the outside date in your agreement may differ depending on how your APS is structured and any amendments negotiated at signing. Your lawyer should confirm your specific outside date at the time of review.

Tarion delay compensation

When a builder misses a firm occupancy date, or provides shorter-than-required notice of a delay, you are entitled to compensation under the Tarion Addendum. The compensation rate is:

• $150 per day for each calendar day of delay beyond the firm date (or beyond the proper notice period)
• Maximum compensation: $7,500 per occurrence

This compensation is intended to cover costs you incur because of the delay — hotel stays, storage costs, extended lease arrangements. You must make a formal claim through Tarion to receive it. Claims must be submitted within the applicable time limits.

You can make delay compensation claims for up to three separate delay events during the pre-closing period, for a potential maximum of $22,500 in total delay compensation on a single transaction. Keep detailed records of any costs you incur as a result of delays — they will support your claim.

Understanding your outside occupancy date

Your outside occupancy date is the single most important date in your purchase agreement from a timeline perspective. It defines the longest you can be held to this transaction before having the right to walk away — or having legal recourse if possession is not given.

To find your outside date, look at the Tarion addendum to your APS. It is listed explicitly. If it is not clearly stated, your lawyer should calculate it from the original tentative occupancy date and the applicable Tarion rules at the time of signing.

The outside date is important for life planning: if you're selling your current home, ending a lease, or making other major decisions around the expected closing of your pre-construction purchase, the outside date is the edge of your planning horizon. Do not plan to a tentative or even a firm date — plan with the outside date in mind and treat anything earlier as a bonus.

What happens if the outside date passes

If the builder cannot give you possession by the outside occupancy date, you generally have the right to walk away from the transaction and receive a full refund of all deposits paid, plus interest as specified in the agreement.

This is a significant legal right — but exercising it requires proper notice. Your lawyer must provide written notice to the builder in accordance with the terms of the Tarion Addendum. If you miss this window or fail to deliver notice correctly, you may be deemed to have waived your right to terminate. The moment the outside date is approaching, contact your lawyer.

In some cases, both parties may agree to extend the outside date rather than terminate. Whether to extend or terminate depends on your circumstances, the market, and what the builder is offering. This is a genuine decision point — not an automatic right or obligation. Your lawyer can advise on the tradeoffs.

Note that builders sometimes invoke force majeure provisions for extraordinary delays — pandemics, material shortages, labour disruptions — which may extend their timeline rights under the agreement. The scope of force majeure clauses varies by agreement and is an area worth reviewing carefully with your lawyer at the time of signing.

How to track your key dates

The dates that matter in a pre-construction purchase are: the original tentative occupancy date, any subsequent revised tentative dates (each should come with a written notice from the builder), the firm occupancy date when set, and the outside occupancy date. Record each with the date of the notice and keep copies of every notice you receive from the builder.

Many buyers lose track of these dates over the years between signing and closing. When a builder sends a delay notice, review it immediately — do not let it sit. If you believe a notice was sent with insufficient lead time, document the date you received it and contact your lawyer.
