Harmonized Sales Tax: Assignment of Purchase and Sale Agreements for Grandparented Housing in Ontario and British Columbia

GST/HST Info Sheet GI-097
July 2010

The Government of Ontario and the Government of British Columbia have introduced a harmonized sales tax (HST) that came into effect on July 1, 2010.

The HST rate in Ontario is 13% of which 5% is the federal part and 8% the provincial part.

The HST rate in British Columbia is 12% of which 5% is the federal part and 7% the provincial part.

This info sheet reflects tax changes included in the New Harmonized Value-added Tax System Regulations, No. 2.

This info sheet explains how the rules apply to the assignment of grandparented purchase and sale agreements for housing in Ontario and British Columbia (B.C.). The rules for grandparented purchase and sale agreements for housing are explained in GST/HST Info Sheet GI-083, Harmonized Sales Tax: Information for Builders of New Housing in Ontario, and GST/HST Info Sheet GI-084, Harmonized Sales Tax: Information for Builders of New Housing in British Columbia.

Definitions for GST purposes, e.g., builder, residential complex, residential unit, residential condominium unit, and substantial renovation, generally apply under the HST, as do the CRA's current policies on the application of the GST to housing. Guide RC4052, GST/HST Information for the Home Construction Industry and GST/HST Info Sheet GI-005, Sale of a Residence by a Builder Who is an Individual explore many of these important terms and concepts. Others are explained in GST/HST Memorandum 19.2, Residential Real Property or related policy statements.

The terms "arm's length", "associated persons" and "specified related person" as used in this info sheet are explained below.

Arm's length

For GST/HST purposes,

In addition, for purposes of the assignment of grandparented purchase and sale agreements for housing in Ontario and B.C., aunts and uncles are considered to be related to their nieces and nephews in applying the arm's length test in this info sheet.

Associated persons

For GST/HST purposes, persons are considered to be associated in the following circumstances:

Specified related person

A specified related person is any person who is not dealing at arm's length with, or who is associated with, the original builder.

The original builder is a builder who enters into a grandparented purchase and sale agreement for newly constructed or substantially renovated housing.

Grandparented purchase and sale agreements

Builders are generally required to charge the HST when they sell newly constructed or substantially renovated housing where both ownership and possession are transferred after June 2010.

However, where ownership and possession of the housing are transferred after June 2010 and the purchase and sale agreement is grandparented, the provincial part of the HST does not apply to the sale of the housing. Only the GST at the rate of 5% applies to the sale.

The grandparenting rules apply only to single-unit houses, residential condominium units and condominium complexes. The grandparenting rules do not apply to multiple unit housing (e.g., an apartment building). A single-unit house includes a detached house, semi-detached house and a rowhouse unit (where such housing is not a condominium), but does not include a duplex, mobile home or floating home.

Assignment of grandparented purchase and sale agreements

Where a purchaser, referred to in this info sheet as the original purchaser, enters into a grandparented agreement of purchase and sale for new housing with the original builder of that housing, the purchaser may assign the agreement to another person (referred to as the "assignee purchaser"). Similarly, that assignee purchaser may assign the agreement to yet another person (also referred to as an assignee purchaser).

If the original builder transfers ownership and possession of the housing to an assignee purchaser after June 2010, the sale of the housing from the original builder to the assignee purchaser is grandparented (not subject to the provincial part of the HST) where the following conditions are met:

Policy Statement P-249, Agreements and Novation may assist in determining whether a purchase and sale agreement has been changed to such a degree that novation has occurred. If novation has occurred, the existing agreement is considered to be terminated and a new agreement is considered to exist.

GST/HST Info Sheet GI-098, Harmonized Sale Tax: Resales of New Housing in Ontario and British Columbia, explains the rules where the original builder or a specified related person acquires or reacquires an interest in the housing.

Example 1

On May 1, 2009, Lynn (the original purchaser) and a builder (the original builder) enter into a written agreement of purchase and sale for a newly constructed detached house. Ownership and possession of the house will transfer after June 2010. As such, the sale of the house to Lynn is grandparented, i.e., the sale is subject to the GST at 5%.

Lynn is acquiring the house for resale and assigns the purchase and sale agreement to Carmela (assignee purchaser) for $10,000 on October 15, 2009. Ownership and possession of the house transfer from the original builder to Carmela on July 15, 2010. There is no novation of the purchase and sale agreement that was entered into between Lynn (the original purchaser) and the original builder. The original builder and Lynn are not associated for GST/HST purposes and are dealing at arm's length. Carmela is not a specified related person. The builder does not reacquire the house or an interest in the house under the assignment agreement.

The sale of the house by the original builder to Carmela (the assignee purchaser) is grandparented since the conditions for grandparenting when there is an assignment of a purchase and sale agreement are met:

  • there is no novation of the purchase and sale agreement;
  • the original builder and original purchaser are dealing at arm's length and are not associated;
  • neither the builder nor a specified related person acquires or reacquires the house or an interest in the house; and
  • the assignee purchaser is an individual.

The sale of the house is subject to the GST at the rate of 5%. Carmela is not required to pay the HST on the purchase of the house from the original builder.

If Lynn had assigned the purchase and sale agreement to a person other than an individual (e.g., a partnership or corporation), the sale of the house by the original builder to that assignee purchaser would not be grandparented. In the case of a single-unit house, all assignee purchasers must be individuals.

The $10,000 paid under the assignment agreement is the purchase price for the sale of an interest in the house supplied by Lynn (the original purchaser) to Carmela (the assignee purchaser). For GST/HST purposes, the sale of the interest is a supply of real property. As no exemption applies to the sale of the interest in this particular case, the supply is a taxable sale. However, as ownership of the interest transfers to Carmela under the assignment agreement on October 15, 2009, (i.e., before July 2010), the HST does not apply to Lynn's taxable sale of the interest to Carmela. As such, the GST at a rate of 5% applies on the $10,000 paid by Carmela to Lynn under the assignment agreement.


Example 2

On May 1, 2009, BuyCo, which is a corporation (the original purchaser) and a builder (the original builder) enter into a written agreement of purchase and sale for a newly constructed residential condominium unit in a condominium complex. Ownership and possession of the unit will transfer after June 2010. As such, the sale of the unit to BuyCo is grandparented, i.e., the sale is subject to the GST at 5%.

BuyCo is acquiring the unit for resale and assigns the purchase and sale agreement to UseCo, a corporation (assignee purchaser) for $10,000 on October 15, 2009. Ownership and possession of the unit transfer from the original builder to UseCo on July 15, 2010. There is no novation of the purchase and sale agreement that was entered into between BuyCo (the original purchaser) and the original builder. The original builder and BuyCo are not associated for GST/HST purposes and are dealing at arm's length. UseCo is not a specified related person. The builder does not reacquire the unit or an interest in the unit under the assignment agreement.

The sale of the unit by the original builder to UseCo (the assignee purchaser) is grandparented since the conditions for grandparenting when there is an assignment of a purchase and sale agreement for a residential condominium unit are met:

  • there is no novation of the purchase and sale agreement;
  • the original builder and original purchaser are dealing at arm's length and are not associated; and
  • neither the builder nor a specified related person acquires or reacquires the unit or an interest in the unit.

The sale of the unit is subject to the GST at the rate of 5%. UseCo is not required to pay the HST on the purchase of the unit from the original builder.

Since this is a residential condominium unit, the original purchaser and the assignee purchaser need not be individuals in order for the sale by the original builder to be grandparented.


Example 3

Ms. Mulinda is the sole shareholder of, and controls, CanCo, a corporation in the business of building and selling new housing. Ms. Mulinda decides to purchase one of CanCo's new houses for her personal use. The written agreement of purchase and sale is entered into on June 1, 2009, and both ownership and possession of the house are to transfer to Ms. Mulinda after June 2010. As such the sale of the house to Ms. Mulinda would be grandparented, i.e., the sale would be subject to the GST at 5%.

Ms. Mulinda changes her mind in May 2010 and assigns the purchase and sale agreement to Francine (assignee purchaser). CanCo transfers ownership and possession of the house to Francine on July 15, 2010.

Although the sale by CanCo to Ms. Mulinda would have been grandparented, the sale by CanCo to Francine (the assignee purchaser) is not grandparented. The conditions for grandparenting when there is an assignment of a purchase and sale agreement are not met because Ms. Mulinda (the original purchaser) and CanCo (the original builder) are associated persons for GST/HST purposes. Francine must pay the HST on the purchase of the house, at the rate of 12% if the house is situated in B.C. or at 13% if the house is situated in Ontario.
