Before you hire a plumber in Ontario

Yes. Plumber (306A) is a compulsory trade in Ontario - working without certification is illegal, not just inadvisable.

Certificate of Qualification, 306A Plumber

The individual doing the work must hold this, or be a registered apprentice working under someone who does. Ask for the certificate number and the name it is issued to. It belongs to a person, not a company.

Verify with: Skilled Trades Ontario maintains the public register of certified tradespeople.

General liability insurance

Two million dollars is the common floor for residential work. Water damage escalates fast, and a burst supply line during a renovation can exceed a small policy in an afternoon.

WSIB clearance

If a worker is injured on your property and the contractor has no coverage, you can be drawn into the claim. A clearance certificate is free for the contractor to pull and takes minutes.

Verify with: WSIB issues clearance certificates directly to the contractor on request.

Questions worth asking

Is the person doing the work certified in 306A, or an apprentice being supervised? Both are fine. You just want to know.
Is this quote flat rate or time and materials? If hourly, what is the estimated range and what happens if it runs over?
Does the job touch a gas line, and if so who holds the TSSA certificate?
Does this need a municipal plumbing permit, and are you pulling it?
What is the warranty on labour, separately from the manufacturer warranty on parts?
