Licensed, Insured, and Accountable

One of the most important questions to ask any plumber is whether they are properly licensed and insured. In Ontario, plumbing work must be performed by a licensed tradesperson, and any company doing drain or sewer work must meet municipal and provincial standards.

BEST Plumbing and Drainage Contractors employs fully licensed plumbers and drainage specialists. Their team meets all Ontario regulatory requirements, carrying the appropriate licenses and insurance coverage to protect both the company and the property owner on every job.

What does this mean practically? It means that work performed by BEST meets code, permits are pulled when required, and in the unlikely event that something goes wrong, you are protected. Unlicensed plumbers may offer a lower upfront price — but the risks of non-compliant work, voided home insurance claims, and poor-quality repairs are simply not worth it.

ℹ️ Quick Answer: Is BEST Plumbing licensed and insured in Ontario? Yes. BEST employs fully licensed plumbers and drainage specialists who meet all Ontario regulatory requirements. The company is licensed, bonded, and insured on every job.
