Buyers of older homes ask questions that documents answer faster than conversation. Assemble what you have, note honestly what you do not, and keep the pack with your listing file.
What documents should a seller of an older Canadian home gather?
Gather permits and inspection records, dated invoices for electrical, plumbing, heating, roofing and insulation work, any environmental testing reports, and warranty documents. Organise them by system and note where records are missing. Documentation reduces uncertainty in negotiation; it does not replace disclosure obligations, which are set provincially.

Missing records are normal. Say what you know, say what you do not, and do not describe work you cannot document. Disclosure obligations differ by province — ask your lawyer or notary and your listing representative what applies to you.
