That is what your lawyer is for. I'm also unsure of the public disclosure rules so I will not say anything specific about wording or amendments requested.
I'm not an old hand at this and X-Condos will be my second purchase if I go through with it. Others here, like V of E, could probably give much more thorough advice.
General guides for a new condo purchase:
1) Watch how your funds are being managed in the trust account to ensure they can meet their obligations according to the Condo Act. If they go bankrupt and the deposits have been mismanaged, you may not necessarily receive all interest you are entitled to if they don't have it. The Vendor is almost always a shell company with no obligations or sources of funding beyond the one specific development.
Until you take ownership (sometimes long after you move in) these funds are yours with someone else managing them.
2) Double check the warranties to ensure they are reasonable. If you can, have your agent compare to other agreements they have. A real-estate agent which specializes in new condominiums (particularly if they have been on the sales staff) is very useful here.
If a builder has had significant problems in the past, their new buildings tend not have that component under warranty. This list can actually tell you quite a bit about their track record.
3) Watch for adjustments with no limits applied to them. Take the maximum of all adjustments and add it to the purchase price as that is likely what you can expect. If there is no limit, your condo may have an infinitely high purchase price (or far higher than what you thought you agreed to).
Ensure that if they do mention a limit in the contract that it is close to what the book mentions. If the book says they expect $2M in for the building in a given category (maintenance fees and the reserve fund being the most obvious), then ensure the contract adjustments for your unit are appropriate given the number of units and the size of your unit. If they don't add up, the vendor has either made a mistake in the calculations for the adjustment OR they anticipate the book value is incorrect and will increase significantly.
I'm not saying don't buy. Just be sure to take a hard look at it and ensure you are okay with it.
I would much rather pay extra on the initial purchase price and eliminate uncapped adjustments and additional fees (potential surprises) rather than be surprised at what the final bill will be.
