Question 1

How much does a plumber charge per hour in Toronto?

Accepted Answer

Licensed Toronto plumbers charge $100–$200 per hour for standard daytime work in 2026. Emergency after-hours rates run $200–$350 per hour. Most plumbers also charge a dispatch or call-out fee of $75–$150 on top of the hourly rate. Many common jobs such as drain cleaning or toilet repairs are priced as flat-rate services rather than by the hour.

Question 2

Do I need a licensed plumber in Ontario?

Accepted Answer

Yes. Under Ontario Regulation 169/99 and the Ontario College of Trades Act, plumbing work in Ontario must be performed by or under the supervision of a licensed journeyman plumber. Homeowners can do minor repairs like replacing a faucet cartridge or showerhead, but any work involving new pipe installation, drain alterations, water heater replacement, or gas connections requires a licensed tradesperson.

Question 3

What should I do in a plumbing emergency?

Accepted Answer

First, locate and close your main water shut-off valve to stop water flow. For most Toronto homes, this is near the front foundation wall in the basement. Then call an emergency plumber at (437) 290-0902. Do not attempt to open walls or remove pipes yourself — you may make the damage worse or void your insurance coverage. Document the damage with photos before cleanup.

Question 4

How do I find my water shut-off valve?

Accepted Answer

In most Toronto single-detached homes, the main shut-off valve is located on the basement floor near the front wall of the house, where the water service enters from the street. It is typically a gate valve (round wheel handle) or ball valve (lever handle). Condos and apartments have individual unit shut-offs inside the unit — often under the kitchen sink, in a utility closet, or near the bathroom.

Question 5

Does homeowners insurance cover plumbing in Ontario?

Accepted Answer

Standard Ontario homeowners insurance typically covers sudden and accidental water damage — like a burst pipe. It does not cover gradual leaks, maintenance failures, or overland flooding. Sewer backup coverage is usually a separate add-on. Basement flooding from municipal sewer overflow is often excluded unless you have purchased sewer backup endorsement. Check your specific policy with your insurer.

Question 6

When do I need a plumbing permit in Toronto?

Accepted Answer

A plumbing permit is required in Toronto for: new plumbing installations, moving or adding drains, water heater replacement, sewer line work, and backflow valve installation. Cosmetic replacements (same-for-same faucet swap, toilet replacement in same location) generally do not require a permit. Your plumber should advise on permit requirements and handle the application as part of the job.

Question 7

Is a backwater valve required in Toronto?

Accepted Answer

Toronto requires a backwater valve for new construction and for any renovation adding basement plumbing fixtures. Existing homes are not mandated but are strongly encouraged. The City of Toronto Basement Flooding Protection Subsidy Program offers up to $1,250 per property for backwater valve installation, sump pump installation, or storm and sanitary sewer disconnection.

Question 8

What is the Toronto backwater valve subsidy?

Accepted Answer

The City of Toronto Basement Flooding Protection Subsidy Program covers up to $1,250 per eligible residential property for the installation of a backwater valve, sump pump, or the disconnection of storm and sanitary sewer connections. The subsidy is available to Toronto property owners only — not Durham, York, Peel, or Halton Region properties. Our plumbers can help with subsidy paperwork.

Question 9

Does the City of Toronto replace lead pipes for free?

Accepted Answer

The City of Toronto replaces the City-owned portion of lead water service lines (from the water main to the property line) at no cost through its Priority Lead Water Service Replacement Program. However, the homeowner is responsible for the private portion (from the property line into the home), which can cost $3,000–$8,000. The City offers a 10-year payment plan option.

Question 10

How much does drain cleaning cost in Toronto?

Accepted Answer

Professional drain cleaning in Toronto costs $150–$300 for basic snake auger service and $300–$600 for hydro-jetting in 2026. Camera inspection to diagnose the cause of recurring blockages adds $100–$200. Emergency after-hours drain calls start at $200. Prices vary slightly across GTA areas — Leaside and Downtown Toronto carry a modest premium versus Durham Region areas.

Question 11

How much does a water heater replacement cost?

Accepted Answer

Tank water heater replacement in Toronto typically costs $1,200–$2,200 for standard 40–60 gallon gas units including the unit and installation. Electric tank units run $900–$1,800. Tankless (on-demand) water heater installation costs $2,500–$4,500 due to more complex venting and gas line requirements. These are 2026 Toronto market rates.

Question 12

What is the cost of sewer line repair in Toronto?

Accepted Answer

Sewer line repair in Toronto ranges from $1,000 for a minor spot repair to $5,000–$15,000 for full line replacement, depending on depth, length, and soil conditions. In Scarborough ravine lots, TRCA excavation permits add $500–$1,500 to the project cost. Camera inspection before repair is included in all our sewer work to accurately scope the job.
