How much does it cost to install a toilet in Ontario? (2026)

Prices checked October 2026. A like-for-like swap is one of the shorter plumbing jobs: shut off the water, lift the old toilet, set the new one on a fresh seal, reconnect the supply line and test for leaks. Most of the price variation comes from what turns up under the old toilet: a broken flange, a seized shut-off valve, a soft subfloor, or a new toilet that does not match the drain position.

How much does a plumber charge to replace a toilet?

Most GTA plumbing shops charge $200 to $450 in labour to remove an old toilet and install a new one in the same place, and a few quote up to $500. The job usually takes one to two hours. At the $110 to $150 an hour most Ontario shops charge for daytime work, that is about $110 to $300 of time, plus a service call or first-hour minimum, a wax or waxless seal and often a new braided supply line.

Those ranges come from 2026 price guides published by Toronto plumbing contractors (Premier Plumbing lists $335 to $500 for a standard installation, City Rooter $200 to $500) and from quotes Toronto and Mississauga homeowners report on RedFlagDeals, mostly about $180 to $330 per toilet. Flat prices usually include taking the old toilet away; check before you agree.

How much does the toilet itself cost?

A builder-grade two-piece toilet costs about $100 to $300 at big-box stores in 2026. A mid-range model, usually one-piece, comfort height (about 43 to 48 cm, or 17 to 19 inches, to the seat) or with a skirted base, runs about $300 to $700. Smart toilets with a built-in bidet usually cost $900 or more before installation. Skirted and one-piece models are heavier and take longer to set level, so some plumbers charge a little more to install them.

Check the rough-in before you buy. That is the distance from the finished wall behind the toilet to the centre of the floor bolts. Most Ontario homes are 12 inches (305 mm), but older houses can be 10 or 14 inches. A toilet with the wrong rough-in either sits off the wall or will not fit, and fixing it means an offset flange or a different toilet. The Ontario Building Code limits a toilet newly installed in a house to 4.8 litres per flush, and most toilets on store shelves meet that.

Wax ring or waxless seal: does it change the price?

Barely; both are cheap next to the labour. A wax ring is the traditional seal and works well, but it can only be pressed down once, so a toilet that is lifted or rocks needs a new one. A waxless rubber or foam seal, such as Fluidmaster's Better Than Wax, can be repositioned and copes better with a flange that sits low under new tile. A solid flange and a toilet that does not rock matter more than which seal is used.

What if the flange is broken or the floor is soft?

A broken flange is the most common extra on a toilet swap. The flange is the ring on top of the drain pipe that the toilet bolts to. If one side has snapped, a metal repair ring screwed over it fixes it for about $50 to $200. If the flange sits well below new tile, an extension ring or thicker seal brings it up. If the pipe is cracked or a cast-iron flange has rusted through, the plumber cuts it out and joins a new one: the $400 to $700 job.

A toilet that has leaked at the base for years often leaves the subfloor around the flange soft. That is carpentry, not plumbing, and can add a few hundred dollars or more. Ask to see the floor once the old toilet is up, before anything new goes down.

Do I need a permit to replace a toilet in Ontario?

Not for a like-for-like replacement in the same spot. The City of Toronto lists repairing and replacing plumbing fixtures as work that does not need a building permit, and the Town of Aurora says the same for repair or replacement of plumbing fixtures. Moving the toilet, adding a new one in a basement or changing its drain is installing or altering plumbing, which does need a permit under the Ontario Building Code. Newmarket lists plumbing alterations as permit work; its building division (905-953-5300 ext. 2400) can confirm whether your particular job needs one.

Can a handyman install a toilet in Ontario?

Many advertise it, but replacing a toilet means disconnecting and reconnecting the water supply and the drain, which is plumbing. Plumber (306A) is a compulsory trade in Ontario under the Building Opportunities in the Skilled Trades Act, 2021: anyone practising it needs a Certificate of Qualification, a provisional certificate or a registered training agreement, and a business may not engage someone who does not have one. Skilled Trades Ontario has not published an exemption for small fixture swaps, so whether a toilet swap alone counts as practising the trade is a grey area.

The practical answer: a handyman is often cheaper, and many homeowners swap their own toilet. But a badly set toilet can leak slowly under the floor where you cannot see it. Anything beyond the swap, such as moving the drain, a new rough-in or a basement bathroom, belongs with a 306A plumber and a permit. You can check any plumber's certificate on the Skilled Trades Ontario public register.

Are there toilet rebates in Ontario in 2026?

We could not find a current toilet rebate for homeowners from the City of Toronto or York Region in October 2026. York Region's $100 toilet incentive is for industrial, commercial and institutional properties only, not houses. Rebate programs come and go, so check your own municipality's water department before you buy if a rebate would change your decision.

What does Doyo charge for a toilet?

Doyo does not sell toilet installation at a set price; its plumbing jobs are Pipe Repair, Drain Cleaning, Faucet Install and Toilet Repair. Toilet Repair is $218.50, Doyo's fee included, for fixing the toilet you have, such as one that runs all night. Plumbers on Doyo hold a Certificate of Qualification (306A), and Doyo checks it before they are offered plumbing work. Your card is charged only when the job is completed.

To replace a toilet, describe the job to the Doyo agent with a photo and say whether you already have the new toilet; nothing is booked until you confirm. Handyman General Repairs ($57.50 an hour) is for small jobs that are not plumbing, electrical or gas work.

How do I avoid overpaying for a toilet install?

• Measure the rough-in before buying the toilet, and tell the plumber the model so they know what they are setting.
• Ask whether the price includes the seal, a new supply line, taking the old toilet away and tax.
• Ask what happens if the flange is broken: a price for a repair ring and a price for a full replacement, agreed before the old toilet comes up.
• Under Ontario's Consumer Protection Act, 2002, a business cannot charge more than 10% over its estimate unless you agree to the new price first.
• If you dispose of the old toilet yourself, Toronto houses can set it out as an oversized item on garbage day. In York Region the rules depend on your town, and the regional waste depots charge a drop-off fee.
