Short answer
Do not stop at whether cannabis was once present. Determine the scale and use, alterations, moisture or electrical impact, municipal or police records, remediation, permits, air-quality or environmental evidence, insurance availability, appraisal response and lender acceptance. A remediated property may still be treated differently by different lenders and insurers.
The buyer concern behind the question
The buyer hears that the property was “fully remediated” and assumes every lender and insurer will accept it. The appraisal or underwriting review later raises marketability, history or documentation concerns.
A practical Ontario example
Illustration only: A former grow operation has municipal remediation documents but limited details about electrical work. Rajiv sends the facts to potential lenders before a firm commitment, while the Realtor, lawyer, inspector and insurer complete their own reviews.
Questions to ask before becoming firm
- Was the activity personal cultivation or a larger operation?
- What alterations, moisture or electrical risks were identified?
- Which remediation, clearance, permit and inspection documents exist?
- Will the proposed insurer cover it without unacceptable exclusions?
- Has the lender reviewed the history and documents in writing?
Practical routes to compare
- Disclose the known history to the broker and insurer early.
- Do not waive financing or property review based on a verbal reassurance.
- Compare A, alternative and short-term financing only after property acceptance and exit are tested.
What each professional can and cannot decide
The Realtor investigates and communicates property facts within the real-estate mandate and advises on offer strategy. The inspector or specialist assesses condition within a defined scope. The lawyer interprets disclosure duties, title, contract language, evidence and remedies. The insurer decides coverage. The appraiser reports value and marketability for the assignment. Rajiv tests qualification, lender property acceptance and closing consequences. RECO regulates Ontario real-estate professionals; it does not set lender underwriting policy. FSRA regulates mortgage-brokering conduct and certain financial sectors; it does not approve the mortgage or create one universal lender policy.
Mortgage and closing consequences
Changed property facts can affect usable rental income, appraisal, insurance, marketability, repair conditions and the amount a lender will advance. Start with a suitable A lender when the borrower and property meet policy. An alternative lender may take a broader view at a higher rate and fee, but still needs acceptable property and evidence. An institutional MIC or private lender may provide a flexible short-term route, including interest-only, amortized, open, partly open or maturity-matched structures in some cases. That route is not an automatic rescue: equity, total cost, legal advice and a credible exit back to suitable A or B financing must be tested.
Verified public guidance
RECO distinguishes physical defects from stigma and advises specific buyer inquiries. Mortgage property acceptance and required evidence are lender and insurer policies, not rules imposed by RECO or FSRA.

Pressure-test this answer
The answer may change if the seller did not know the fact, the concern was visible, the buyer received warning signs, the wording was only marketing opinion, records contradict the statement, the defect was concealed, or the agreement allocates the risk differently. A representation can also be important without creating the remedy a buyer expects. Ask what is known, what is assumed, what evidence is missing and which professional is qualified to decide it. Before waiver, compare the cost of investigation with the buyer’s worst reasonable post-closing exposure. After a firm agreement, let the lawyer direct the response.
