Ask before closing

Checklist

  • Confirm whether the price you entered is the APS listed/contract price or a base price before HST.
  • Ask the builder whether the GST/HST rebate is already assigned or reflected in the contract price.
  • Ask the builder whether federal and Ontario rebate amounts will be credited on the statement of adjustments at closing.
  • Ask your lawyer which rebate path applies to your agreement date and buyer status.
  • Ask your lender whether the CMHC premium is added to the mortgage and confirm the Ontario PST cash amount.

  • Ontario enhanced rebate rules are marked verify-before-relying until final launch source review.
  • Verify the builder's construction timeline against Ontario's temporary enhanced HST rebate backgrounder before relying on the number.
  • Builder rebate treatment is unknown.
