The First-time Home Buyers' Tax Credit was introduced as part of 'Canada's Economic Action Plan' to assist Canadians in purchasing their first home. It is designed to help recover closing costs such as legal expenses, inspections, and land transfer taxes.

As you have not purchased the home, you would be ineligible to make the claim. CRA does not require supporting documents when you claim this credit on your tax return, however if they do, you must present documents supporting the purchase of the home.
