(On the other hand, some owner agreements allow the owner himself to freely assign the agreement to any other contractor registered with Tarion, which completely frees the owner from his obligations.) This is largely due to new construction: for new buildings with typically long closing dates (often 18 months or more), an order is particularly attractive in situations where the owner has already sold all the works under development very early, but where there is still a need for soon-to-be-completed housing and new condominiums in development. Note that the new buyer may want to take steps to protect his position in this regard. For example, when negotiating the transfer contract, the new purchaser should require the agreement to receive written confirmation from the owner that a New Housing Rebate HST will be credited at the time of its conclusion, provided that the qualifying requirements are met by other means. Otherwise, if this obligation is not made in writing, the owner may exercise his discretion as to whether he should credit the purchaser with the amount of the rebate at closing, withhold it and compel the new purchaser to apply to the credit rating agency immediately after closing. It is particularly important to obtain this written obligation, as there is likely to be no prior relationship between the owner and the new purchaser. Many purchase and sale agreements include a largely standard “no-assignment” clause, which gives the original purchaser “direct or indirect” steps to “rent, sell, sell, transfer, transfer, sell, transfer, transfer, transfer or otherwise sell.” In the end, the basic clause contained in a purchase and sale agreement may or may not authorize the transfer of the contract to a new purchaser and, if permitted, is subject to certain conditions, such as the written agreement of the owner. Most agreements embellish this basic clause by adding other written provisions such as: OREA provides a standard form that can be used, although in many cases the contractors who authorize the orders insist that the original buyer and the new buyer use the appropriate assignment forms of the owner instead of the standardized orea version.
