Ontario Licensing Requirements for Cleaning Contractors

Cleaning companies in Ontario do not require a specific licence but should carry commercial liability insurance and WSIB coverage. For mould remediation, look for IICRC (Institute of Inspection, Cleaning and Restoration Certification).

Beyond trade-specific licensing, every cleaning contractor you hire in Ontario should provide:

Commercial general liability insurance — minimum $2 million coverage
WSIB clearance certificate — protects you if a worker is injured on your property
Business registration — registered with the Ontario government
Municipal permits — where required for the specific work being done

What to Look For in a Cleaning Contractor

Experience with your project type. A contractor who specialises in your specific need will deliver better results than a generalist.
Strong local reputation. Check Google reviews (4.0+ rating), ask for cleaning-specific references, and look for contractors listed in professional directories.
Clear communication. How quickly do they respond? Do they explain things clearly? Communication quality during the quote process predicts communication quality during the project.
Detailed written quotes. A professional quote itemises labour, materials, permits, and timeline. Vague one-line quotes are a red flag.
Appropriate insurance and credentials. Ask for copies. A contractor who hesitates is one to avoid.

Red Flags — When to Walk Away

No written contract. Verbal agreements offer zero protection.
Demands cash only. Reputable businesses accept multiple payment methods and provide receipts.
No insurance or refuses to show proof. You are taking on massive liability.
Quote is dramatically lower than competitors. They are either cutting corners or planning to upsell later.
Pressures you to decide immediately. Real professionals give you time to compare.
Cannot provide references. Either they are new (higher risk) or past clients were unhappy.
Wants full payment upfront. Standard is a deposit (10-30%) with progress payments.
