Water Service Options in Toronto

Unlike electricity or internet services, water service in Toronto is fully municipal — meaning there is one provider and no competition, but homeowners still have important responsibilities and billing considerations.

Who Provides Water in Toronto?

The City of Toronto Water Division provides:

• Drinking water supply

• Wastewater (sewer) service

• Stormwater management services

All residential properties connected to municipal infrastructure receive water through this system.

There are no private residential water utilities within Toronto city limits.

Where Does Toronto’s Water Come From

Toronto’s drinking water is sourced from Lake Ontario, one of the Great Lakes.

Water is drawn through deep offshore intake pipes and treated at large municipal treatment plants before being distributed across the city.

Why this matters to homeowners

• Reliable year-round freshwater supply

• Consistently monitored and treated drinking water

• Slightly harder water than some Canadian cities, which may cause mineral buildup over time

How Water Gets to Your Home

Every serviced home typically has:

• A water service line connecting the home to the city water main

• A smart water meter installed inside the property

• Interior shut-off valves for emergencies

Water pressure is maintained through pumping stations and elevated storage reservoirs across Toronto.

How Water Billing Works

Water is metered, meaning you pay based on usage.

Bills are typically issued every 3–4 months.

Charges included

Your bill usually combines:

• Water consumption

• Sewer (wastewater treatment) charges

• Stormwater costs

• Fixed service charges

Even if usage is low, base service fees still apply.

Wastewater charges are calculated based on incoming water usage.

What Happens When You Buy and Move Into a Home

When ownership changes:

• Your real estate lawyer notifies the City of Toronto.

• The utility account transfers to the new owner.

• Final meter readings determine buyer/seller cost split.

• New billing begins under the new owner.

Important:
Water bills are tied to the property, not the individual homeowner, and outstanding balances are typically settled during closing.

Homeowner Responsibilities

You are responsible for:

• Interior plumbing and leaks

• Frozen pipes within the home

• Private water service line on your property

• Maintaining access to the water meter

• Monitoring usage for unexpected increases
