How to Fill Out OREA Form 100?

Step 1: On the first page, you need to write down the name of a buyer and a seller.

Step 2: Complete the details on the property, including address and frontage.

Step 3: Name the purchase price and the deposit you are ready to pay as a buyer. Put the dates and initials of both parties.

Step 4: On page 2, fill in the fax and email fields for delivery of documents if the parties will use them, and list the chattels included, the fixtures excluded and any rental items. In the HST clause, if the sale of the property is subject to HST, state whether HST is included in or in addition to the purchase price; if the sale is not subject to HST, the seller agrees to certify that on or before closing. Under the pre-set clause, any HST on chattels, if applicable, is not included in the purchase price.

Step 5: Complete the page by putting your initials.

Step 6: Pages 3 and 4 contain the pre-printed standard terms of the agreement; read them and initial each page. On page 3, clause 8 (Title Search) also asks for the Requisition Date, the deadline for the buyer to examine title, and the property's present use. These terms are part of the agreement. A provision the parties add (for example in Schedule A) overrides a pre-set term only to the extent of a conflict or discrepancy; the other pre-set terms still apply.

Step 7: Page 5 is where the buyer and the seller sign and date the agreement; there is a witness line next to each buyer's and seller's signature. If the property is the seller's matrimonial home, the seller's spouse generally has to consent to the sale under the Family Law Act; page 5 has a Spousal Consent block for this. There is a block for brokerage information too.

Step 8: In Schedule A on the last page, identify the parties, property and agreement date, set out how the balance of the purchase price will be paid, and include any agreed additional terms. All parties initial the schedule; their full signatures go on page 5.
