What does it cost to buy, and what does it cost to hold?
The purchase price is the number everybody publishes. The monthly carrying cost is the number that decides whether the purchase works, and it is made of three separate charges that are usually quoted separately or not at all.

What are the deposit and assignment terms?
This is the part that decides whether a preconstruction purchase is a good one, and it is the part every other listing leaves blank. Everything here comes from the developer's published material or from the agreement, and none of it replaces reading the agreement with your own lawyer.

What should you check before you sign anything?
Four things that apply to every preconstruction purchase in Ontario, whatever the project. There are more of them on our full guide.
You have ten days to change your mind
Buying a condominium before it is built is not like buying a resale home. Ontario gives you a rescission period of ten calendar days, and during it you can cancel with no penalty and get your deposit back in full.
The clock does not start when you sign. It starts once you hold all three of the agreement of purchase and sale, the disclosure statement, and the condominium buyers guide. If the developer makes a material change to the disclosure statement later, the period starts again.
Use the ten days. That is the window in which your own lawyer reads the agreement, and it is the only point in the whole process where walking away costs you nothing.
Ten calendar days is the Home Construction Regulatory Authority’s own wording, on the page linked below. The HCRA is the body that licenses new home vendors in Ontario.

Your deposit is protected up to twenty thousand dollars
Tarion protects deposits on a new condominium unit up to twenty thousand dollars. A typical deposit on a Toronto preconstruction condominium is fifteen or twenty percent of the purchase price, which on a seven hundred thousand dollar suite is well past that ceiling.
The gap above twenty thousand dollars is covered only by the way your agreement holds the money in trust and by any excess deposit insurance the developer arranges. Ask which one applies to you, and ask to see it in writing.
You will pay to live there before you own it
There is a stretch between the day you move in and the day the building is registered and the unit is legally yours. It is called interim occupancy, and it can run from a few weeks to more than a year.
During it you pay an occupancy fee made up of three parts: interest on the unpaid balance of the purchase price, the estimated monthly municipal taxes for your unit, and the projected common expense fee. None of it comes off the purchase price. It is not a mortgage payment and it builds you no equity.
Work out what that figure will be before you sign, not after. On a small suite it is often close to what the unit would rent for, and on a large one it can be more.

Ask whether the occupancy date is tentative or firm
These are two different things and the difference is worth money. A tentative occupancy date can be moved more than once, with ninety days written notice each time, and no compensation is owed to you.
A firm occupancy date is different. If the builder misses it you are owed one hundred and fifty dollars a day up to a maximum of seven thousand five hundred dollars, plus a further one thousand five hundred dollars if they failed to give you ten days notice of the delay.
There is also an outside occupancy date, the last date the agreement permits. If the unit is not ready by then you have thirty days in which you can terminate and have your deposit returned with interest.
Almost every listing you will read anywhere prints a bare year and says nothing about which kind of date it is. We print the kind, when the developer has published it.
Where did these figures come from?
Every number above is tied to the page it was read on. If one of them is out of date, tell us and we will check it.
