A legitimate cash buyer will not hesitate to provide this. Proof of funds should show an amount that actually covers the purchase price plus closing costs, dated recently enough to reflect the buyer's current position, and it should come from the buyer's own institution rather than a document that is easy to fabricate.
Your lawyer is the second checkpoint. Every Saskatchewan sale closes through a lawyer, and a real buyer will have engaged one, or be ready to within 2 to 3 days, to handle the title search through Information Services Corporation and the transfer of funds.
A cash offer with no proof of funds, an unusually fast timeline and pressure to skip normal conditions is the classic pattern of a fraudulent offer, and it deserves more scrutiny, not less.
