City of Toronto

Licensed plumbers in Toronto.

We hold a City of Toronto Plumbing Contractor licence, which means we can pull permits and take legal responsibility for plumbing work anywhere inside the city.

Toronto is not one plumbing market. A semi in Riverdale built in 1912 has almost nothing in common with a 2019 condo tower on the waterfront, and the problems that walk in the door are completely different. In the old city we are usually dealing with what previous decades left behind: galvanized supply lines that have scaled shut from the inside, cast iron stacks rusting through at the base, clay laterals with roots in every joint. In newer stock the calls are more often about fixtures, water heaters, and work that was done quickly during a build.

That age gap is not a figure of speech. Around 58 percent of Toronto's occupied dwellings were built before 1981, against roughly 12 percent across the rest of the Greater Toronto and Hamilton Area. The practical consequence is that a Toronto plumbing quote depends heavily on the address. Knowing roughly what is behind the wall in a given neighbourhood, and what era of work has been layered on top of it, is most of the job. It is also why we would rather see the property than price it over the phone.

We work across the old city and the amalgamated districts for homeowners, landlords, property managers, contractors and builders, on everything from a single repair to a full building rough-in.

What we run into on Toronto plumbing calls.

Old housing stock, and what is usually behind the plaster

Much of the pre-war housing between the Humber and the Don was originally plumbed in galvanized steel.

Galvanized does not fail by leaking first. It fails by closing up, scaling inward until the hot side of a shower runs at a trickle while the cold seems fine. Homes from the 1970s through the 1990s bring a different problem: Kitec, which insurers and buyers both ask about.

If we open a wall and find either one, we will tell you what we found and what replacing it would actually involve before anyone commits to anything.

Basement flooding, backwater valves and the City subsidy

Toronto pays 80 percent of the cost of a backwater valve, a sump pump and severing the storm connection.

Battery backup and a home plumbing assessment are covered too, each capped on its own and capped again in total. The amounts have been revised more than once, so confirm the current figures with the City before you budget around them.

Two conditions catch people out: your downspouts have to be disconnected, and the work must be done by a contractor holding a valid City of Toronto business licence. We hold one. The other thing worth understanding is that a backwater valve and a sump pump solve different problems.

The valve stops the municipal sewer backing into your basement. The pump handles the water arriving around the foundation. Installing one when you needed the other is a common and expensive mistake.

Lead water services in the older neighbourhoods

Homes built before the mid-1950s may still have a lead water service.

Responsibility is split: the City handles the public portion from the watermain to the property line, and the private portion from the property line into the house belongs to the owner. Replacing only one half leaves lead in the ground and can disturb the remaining section.

If you are already opening the front yard for other work, that is the moment to deal with the whole service rather than half of it.

Cross-connection control under Chapter 851

Toronto's water supply by-law requires premise isolation on industrial, commercial and institutional properties, and on residential buildings of four storeys or more or over 600 square metres.

Note that the threshold is storeys and floor area, not unit count. A widely-copied figure of five or more units is simply wrong, and property managers have budgeted around it. Devices are tested annually, the report goes to the City on its own form within a week of the test, and a cross-connection survey has to be refreshed every five years.

Houses under Part 9 of the Building Code are generally exempt unless there is an auxiliary water supply on the property. Send us the notice if you are unsure which category you are in.

Who is actually allowed to do backflow work here

Toronto's by-law sets out, function by function, who may survey, install, repair and test a backflow preventer.

It is narrower than most owners expect. A professional engineer with the cross-connection certification can survey and test but cannot install or repair. Sprinkler fitters and millwrights can test only. The one credential stack authorized for all of it, fire protection systems included, is a licensed Master Plumber holding a City of Toronto plumbing contractor licence together with the cross-connection control certification.

That is what we hold, which is why a failed device does not turn into a second contractor and a second visit.

Questions

Plumbing in Toronto.

Are you licensed to work in the City of Toronto?

Yes. We hold a City of Toronto Plumbing Contractor licence alongside a Master Plumber licence and Red Seal certification. That licence is what allows a contractor to take out plumbing permits within the city and be held responsible for the work. We are also fully insured and WSIB covered.

Do I need a permit for plumbing work in Toronto?

Often, yes. New plumbing, relocating fixtures, replacing drainage or venting, and most rough-in work require a plumbing permit through Toronto Building. Straight like-for-like repairs and fixture swaps generally do not. We will tell you which category your job falls into before we start, and we handle the permit and inspection scheduling when one is needed.

Who is responsible for the sewer line under my front lawn?

In Toronto the City is responsible for the portion of the sewer lateral in the public right-of-way, and the property owner is responsible for the private portion running from the property line into the house. When a lateral backs up repeatedly, a camera inspection is the cheapest way to find out which side of that line the problem actually sits on before anyone starts digging.

Do you charge extra to come into downtown Toronto?

No. Travel inside our service area is built into our pricing, so there is no separate trip fee for downtown, the old city or any of the districts. Parking and building access are worth mentioning when you book, particularly for condos and commercial units, so we can plan the visit properly.

Does my Toronto house need a backflow preventer?

Usually not. The by-law targets industrial, commercial and institutional properties, plus residential buildings of four storeys or more or over 600 square metres. Houses falling under Part 9 of the Building Code are generally exempt unless there is an auxiliary water supply on the property: a well, a cistern, or in some cases an irrigation system. If a testable device is already installed on your home, it needs testing regardless.

How hard is Toronto's water?

Toronto's supply averages around 119 mg/L as calcium carbonate, roughly seven grains per gallon, which is moderately hard and above Health Canada's operational guideline of 80 to 100 mg/L. In practice that means scale on fixtures and aerators, and it means a tankless water heater in this city needs periodic descaling rather than being fitted and forgotten.

Can you work in a Toronto condo?

Yes, and it needs a bit more planning. Most buildings require notice to property management, a certificate of insurance on file, and a booked window for any riser isolation or water shut-down. Tell us the building when you enquire and we will work out what management needs from us before the appointment.
