What Is Considered a Plumbing Emergency?
A plumbing emergency is any situation that poses immediate risk to your property, health, or safety—and cannot safely wait until regular business hours. The key distinction: if leaving the problem for 8-12 hours would cause significant damage or create dangerous conditions, it's an emergency requiring 24/7 response.
Many Toronto homeowners question whether their situation truly warrants an emergency call and the premium rates that come with it. Here's a clear framework to help you decide:
It's an Emergency If:
- Active water flooding into your home from any source
- Burst or broken pipes spraying water
- Sewage backing up into bathtubs, toilets, or floor drains
- Complete loss of water supply to your entire home
- Gas smell near water heater or plumbing fixtures
- Frozen pipes during winter (burst risk imminent)
- Water heater leaking significantly or making unusual sounds
- Sump pump failure during heavy rain or snowmelt
Can Usually Wait Until Morning:
- Single slow drain (kitchen or bathroom)
- Dripping faucet
- Running toilet
- Low water pressure (if water still flowing)
- Minor leaks under sink (use bucket overnight)
The financial difference matters: emergency calls typically cost 50-100% more than standard service calls. But waiting on a true emergency—like a burst pipe—can result in thousands of dollars in water damage within hours. When in doubt, call and describe your situation. A reputable 24/7 plumber will honestly tell you whether immediate response is necessary.
8 Types of Plumbing Emergencies in Toronto
Understanding the specific type of emergency you're facing helps you communicate effectively with dispatchers and take appropriate immediate action. Here are the most common plumbing emergencies we respond to across the Greater Toronto Area:
1. Burst Pipes
Severity: Critical | Response time: Under 30 minutes
Burst pipes can release 400+ litres of water per hour into your home. In Toronto's harsh winters, pipes in exterior walls, unheated garages, or poorly insulated areas are especially vulnerable. Signs include sudden water pressure loss, visible water spraying, or unexplained wet spots on walls/ceilings.
Immediate action: Shut off main water supply immediately, then call emergency plumber.
2. Sewage Backup
Severity: Critical | Health hazard present
When sewage backs up through floor drains, bathtubs, or toilets, it creates both property damage and serious health risks. Common causes include main sewer line blockages, tree root intrusion, or municipal sewer issues. Toronto's aging infrastructure makes this more common in older neighborhoods like The Annex, Cabbagetown, and Riverdale.
Immediate action: Don't use any plumbing fixtures, keep family and pets away from contaminated areas, call immediately.
3. Major Water Leaks
Severity: High | Damage accumulating
Major leaks from supply lines, water heaters, or fixtures can cause significant damage even without visible flooding. Watch for water stains spreading on ceilings, unexplained water bill spikes, or sounds of running water when no fixtures are on.
Immediate action: Locate leak source if safe, shut off water supply to that fixture or main valve, contain water with towels/buckets.
4. Frozen Pipes
Severity: High | Time-sensitive
Toronto temperatures regularly drop below -15°C in winter, creating prime conditions for frozen pipes. Signs include no water flow from specific fixtures, frost visible on exposed pipes, or unusual sounds when opening faucets. The real emergency: frozen pipes can burst as they thaw.
Immediate action: Never use open flame to thaw, keep faucet open, apply gentle heat with hairdryer, call professional before pipe bursts.
5. Water Heater Failure
Severity: High | Potential flooding and safety risks
A failing water heater can leak 150-300 litres of water, and in severe cases, pressure buildup creates safety hazards. Warning signs include rust-colored water, loud popping/rumbling sounds, water pooling around the base, or visible corrosion on the tank.
Immediate action: Turn off power (gas valve or electrical breaker), shut off cold water supply to heater, call immediately if actively leaking.
6. Sump Pump Failure
Severity: High during rain/snowmelt
For Toronto homes with basements, sump pump failure during heavy rain or spring thaw can mean rapid basement flooding. Listen for your sump pump cycling—if it's running constantly or not at all during wet weather, there's a problem.
Immediate action: Check if pump is receiving power, clear any debris from pit, use backup pump or wet/dry vacuum while waiting for service.
7. Gas Line Issues Near Plumbing
Severity: Critical | Safety emergency
While primarily a gas company issue, gas leaks near water heaters or gas-powered plumbing fixtures require immediate attention. If you smell gas (rotten egg odor) near any plumbing appliance, this is a safety emergency.
Immediate action: Don't use electrical switches, evacuate immediately, call Enbridge Gas (1-866-763-5427) from outside, then call plumber for appliance assessment.
8. Complete Loss of Water
Severity: Moderate to High
Total water loss can indicate a main line break, frozen main, or municipal issue. Before calling an emergency plumber, check with neighbors—if they also have no water, it's likely a municipal issue. Toronto Water's emergency line: 311.
Immediate action: Check neighbors' water, contact Toronto Water (311) if widespread, call plumber if issue is isolated to your property.

What to Do While Waiting for Emergency Plumber
The actions you take in the first 15-30 minutes of a plumbing emergency can significantly reduce damage and keep your family safe. Follow this step-by-step protocol:
Step 1: Shut Off the Water (Most Critical)
Knowing your shut-off valve location is the single most important piece of emergency preparedness. Most Toronto homes have the main shut-off valve in one of these locations:
- Basement: Near the front wall where the water line enters (most common)
- Crawl space: Along the foundation wall
- Utility closet: Near the water meter
- Outside: Meter box near street (requires key)
Turn the valve clockwise until fully closed. If you can't find or turn your main valve, shut off water at the individual fixture (under sinks, behind toilets, or near water heater).
Step 2: Turn Off Water Heater
If you've shut off the main water supply, also turn off your water heater to prevent damage from heating an empty tank:
- Gas water heater: Turn the gas valve to "pilot" or "off" position
- Electric water heater: Switch off the dedicated breaker in your electrical panel
Step 3: Open Faucets to Drain Remaining Water
After shutting off the main supply, open the lowest faucet in your home (often a basement laundry sink) to drain water remaining in the pipes. This reduces potential leak volume and relieves pressure.
Step 4: Contain the Damage
- Place buckets under active leaks
- Use towels or mops to prevent water from spreading
- Move furniture, electronics, and valuables away from wet areas
- If flooding is significant, use a wet/dry vacuum if available
Step 5: Address Electrical Safety
Warning: Water and electricity are a dangerous combination. If water is near electrical outlets, appliances, or your electrical panel, turn off power at the main breaker before walking through standing water.
Step 6: Document for Insurance
Before cleanup begins, take photos and video of:
- The source of the leak/damage
- All affected areas and items
- Water levels and spread of damage
- Any damaged personal property
This documentation is essential for insurance claims. Most homeowner policies cover sudden water damage (like burst pipes) but not gradual leaks or neglected maintenance issues.
Step 7: Prepare for the Plumber
- Clear access to the problem area
- Note when the problem started and any sounds/signs you noticed
- If safe, locate any relevant shut-off valves near the problem
- Have a flashlight ready if the issue is in a dark area

(647) 554-4356How to Choose an Emergency Plumber in Toronto
During an emergency, you need to make quick decisions—but not reckless ones. Here's how to verify you're hiring a qualified professional, even at 2 AM:
Essential Qualifications to Verify
1. Ontario Plumbing License
In Ontario, plumbers must hold a Certificate of Qualification from Skilled Trades Ontario (formerly Ontario College of Trades). Ask for their license number and verify at skilledtradesontario.ca. Unlicensed work can void warranties, violate code, and create liability issues.
2. Liability Insurance
A legitimate plumbing company carries at least $2 million in liability insurance. This protects you if work causes additional damage. Ask for proof of insurance before work begins.
3. Workers' Compensation
Ensure the company has WSIB (Workplace Safety and Insurance Board) coverage. Without it, you could be liable for injuries occurring on your property.
Questions to Ask Before Authorizing Work
- What is your service call fee? Get this in writing or verbally confirmed
- What are your hourly rates for emergency service?
- Will you provide a written estimate before starting repairs?
- Are you licensed with Skilled Trades Ontario? Ask for the number
- Do you guarantee your work? Get warranty terms in writing
- How soon can you arrive? Get a realistic timeframe
Red Flags to Watch For
- No license number provided or reluctance to share it
- Cash-only payments with no receipt
- No written estimate before starting work
- Demanding full payment upfront before work is complete
- Arriving in unmarked vehicle with no company identification
- Pressuring you to replace when repair is possible
- Unable to explain what's wrong in plain language
Why Reviews Matter (But Check Them Carefully)
Online reviews are helpful but can be manipulated. Look for:
- Detailed reviews mentioning specific work performed
- Responses from the company to both positive and negative reviews
- Consistent patterns across multiple platforms (Google, HomeStars, Yelp)
- Reviews mentioning emergency service specifically
Water Pro maintains a 4.9-star rating across 5,234+ reviews, with specific feedback on our emergency response times and transparent pricing. We encourage you to check our reviews on Google and HomeStars.
Toronto-Specific Emergency Plumbing Considerations
Toronto's unique infrastructure, climate, and regulations create specific challenges for emergency plumbing. Here's what local homeowners need to know:
Aging Infrastructure in Older Neighborhoods
Many Toronto neighborhoods built before 1960 still have original cast iron or clay sewer lines. Areas with higher emergency call volumes due to aging infrastructure include:
- The Annex - Victorian-era homes with original plumbing
- Cabbagetown - 100+ year old brick homes, clay sewer lines
- Riverdale - Mix of old and renovated homes with varied plumbing
- Leslieville - Rapid development putting strain on old infrastructure
- High Park - Large mature trees contributing to root intrusion
- Beaches - High water table creating sump pump demands
Winter Emergency Preparedness
Toronto's winters are harsh, with temperatures regularly dropping to -20°C or colder. Winter plumbing emergencies spike in January and February. Key vulnerabilities:
- Pipes in exterior walls without adequate insulation
- Unheated garages with water supply lines
- Basement windows near plumbing fixtures
- Outdoor hose bibs not properly winterized
- Vacation properties left unheated
City of Toronto Permit Requirements
Some emergency repairs require City of Toronto permits, especially:
- Main water line replacement (always requires permit)
- Sewer line replacement (always requires permit)
- Water heater replacement (permit required in some cases)
- Backwater valve installation (permit required)
A licensed plumber will advise when permits are needed and handle the application process. Emergency repairs can proceed to stop immediate damage, with permits obtained for permanent repairs.
Toronto Water and Municipal Issues
Sometimes what seems like a home plumbing emergency is actually a municipal issue:
- Complete water loss: Check with neighbors first—could be municipal main break
- Sewer backup during heavy rain: May be overwhelmed municipal combined sewer
- Discolored water after main work: Often municipal flushing, not your pipes
Toronto Water Emergency Line: 311 (available 24/7)
Check the City of Toronto Water Services website for planned maintenance and known issues in your area.
Subsidy Programs for Qualifying Repairs
The City of Toronto offers rebate programs that can offset emergency repair costs:
- Basement Flooding Protection Subsidy Program: Up to $3,400 for backwater valve and sump pump installation
- Lead Pipe Replacement Program: Assistance for replacing lead water service lines
While these programs don't apply to emergency work directly, they can help fund permanent solutions after an emergency reveals underlying issues.

Frequently Asked Questions
Quick answers to the most common emergency plumber questions from Toronto homeowners:
A plumbing emergency includes burst pipes, sewage backups into your home, complete loss of water supply, gas leaks, flooding from any source, or any situation causing active water damage. If left unattended for even a few hours, these issues cause significant property damage. Single slow drains, dripping faucets, or running toilets can usually wait until regular business hours.
Emergency plumber costs in Toronto range from $150-$300 for the service call plus $100-$200 per hour for labor. After-hours calls (nights, weekends, holidays) typically add 50-100% to standard rates. Total costs for common emergencies: burst pipe repair $300-$800, sewage backup $400-$1,200, water heater emergency $250-$600. Always get a written estimate before work begins.
Yes, always locate and turn off your main water shut-off valve immediately during a plumbing emergency. This stops water flow and prevents additional damage while waiting for the plumber. Most Toronto homes have the shut-off valve near the water meter in the basement or crawl space. Turn the valve clockwise until fully closed.
Most 24/7 emergency plumbers in Toronto arrive within 30-60 minutes for genuine emergencies. Response times vary by location and time of day. Downtown Toronto typically sees faster response times (20-40 minutes) while outer GTA areas may take 45-90 minutes. At Water Pro, our average response time is 30-45 minutes across the GTA.
A single clogged drain is usually not an emergency and can wait for regular business hours. However, if sewage is backing up into your home, multiple drains are clogged simultaneously, or you smell gas/sewage, treat it as an emergency. A complete main line blockage causing sewage backup requires immediate attention.
Yes, true 24/7 emergency plumbers work on all holidays including Christmas, New Year's, and statutory holidays. Expect holiday rates to be 1.5x to 2x the standard emergency rate. Always confirm pricing before authorizing work to avoid surprise charges. Water Pro provides emergency service 365 days a year.
While waiting: 1) Turn off the main water supply, 2) Turn off the water heater, 3) Open faucets to drain remaining water, 4) Move valuables away from the affected area, 5) Document damage with photos for insurance, 6) Place buckets under active leaks, 7) Turn off electricity if water is near electrical outlets. These steps minimize damage during the wait.
In Ontario, verify plumber licensing through Skilled Trades Ontario (formerly Ontario College of Trades). Ask for their Certificate of Qualification number and verify online at skilledtradesontario.ca. Licensed plumbers carry liability insurance and are accountable to provincial standards. Never hire unlicensed plumbers—their work may violate code and void warranties.
