Do I need a licensed plumber in Ontario?
Yes. In Ontario, anyone performing plumbing work for compensation must hold a Certificate of Qualification (306A — Plumber) issued by Skilled Trades Ontario. Unlicensed plumbing work is illegal under provincial law, may void your home insurance, and will fail building inspections. Verify any plumber's active licence at skilledtradesontario.ca.
Does plumbing work require a permit in Ontario?
It depends on the scope. Swapping a faucet, toilet, or showerhead in the same location generally does not need a permit. However, new rough-in work, relocating drains or supply lines, adding a bathroom, installing a water heater in some municipalities, or connecting to a well or septic system almost always requires a building permit under the Ontario Building Code. Your licensed plumber should manage permit applications for work that requires them. See Ontario Plumbing Regulations for full details.
How much does a plumber cost per hour in Ontario?
Licensed plumbers in Ontario typically charge $100–$175 per hour for scheduled work, plus a service call fee of $150–$250. Emergency and after-hours rates run 1.5–2× the standard rate. Rural Renfrew County properties may be charged a travel surcharge of $50–$150 for locations outside a contractor's primary service area — particularly Deep River, Bancroft, and Hawkesbury. See the full cost guide for a complete breakdown by service type.
What is a Certificate of Qualification 306A?
The 306A is Ontario's journeyperson licence for the Plumber trade, issued by Skilled Trades Ontario. It confirms the holder has completed an approved apprenticeship and passed a provincial qualification exam. It is the minimum credential required to legally perform plumbing work for compensation in Ontario. Apprentices (306A apprentice) must work under direct, on-site supervision of a 306A journeyperson and cannot work independently.
Can I do my own plumbing in Ontario?
A homeowner can perform plumbing work in their own primary residence without a 306A licence, but a building permit is still required for any work that would otherwise need one, and the work must pass inspection. This means a homeowner can legally replace fixtures or install a water heater, but must pull a permit for new rough-in and have it inspected. Work on rental properties, cottages, or any property you do not personally occupy requires a licensed plumber — no exceptions.
How do I find a licensed plumber in Renfrew County?
Search the Skilled Trades Ontario directory at skilledtradesontario.ca to verify any plumber holds an active 306A certificate. Most licensed plumbers serving Renfrew County are based in Pembroke, Petawawa, Renfrew, or Arnprior. For properties in Deep River, Bancroft, or Hawkesbury, expect travel surcharges and longer scheduling lead times. Always request a written quote and confirm the licence number before authorizing any work.
What should I do in a plumbing emergency?
First: shut off the water supply. Know where your main shutoff is before an emergency happens — this is the single most important preparation a rural homeowner can make. For a burst pipe, turn off the main immediately. For a sewage backup, stop all drain and toilet use. For no water on a well system, check the pressure tank gauge and the circuit breaker for the well pump before calling. Then call a licensed plumber — confirm emergency rates upfront, as after-hours calls in rural Ontario typically run 1.5–2× the standard hourly rate.
