Frequently Asked Questions

What are the biggest red flags for contractor scams?

Demanding large upfront deposits, no written contract, no insurance proof, pressure to sign immediately, no physical business address, and unusually low quotes.

How much deposit should I pay a contractor?

Never more than 10 to 15 percent or $5,000, whichever is less. Reputable contractors do not need large deposits — they have lines of credit for materials.

How do I verify a contractor is legitimate?

Verify insurance directly, check WSIB clearance, search business registration, check BBB, read online reviews, and contact local references.

Avoid cash payments — they eliminate your paper trail for warranty claims, insurance disputes, or legal action. Always get receipts.

What is the holdback rule in Ontario?

Ontario's Construction Lien Act requires a 10 percent holdback for 45 days after completion to protect against unpaid subcontractor claims.
