Updated February 2026 | By the Plumbing Montreal Team
Quick Answer
Garbage disposal installation in Montreal (also called a garburator) costs $300–$650 CAD total, including the unit and professional labour. Unlike Toronto and Ottawa, Montreal has not banned garburators — they are legal for residential use. The best models for Montreal homes include the InSinkErator Evolution series, Waste King L-8000, and Moen GX series. Professional installation by a licensed plumber takes 1–2 hours and ensures proper plumbing and electrical connections.
A garbage disposal — or garburator as Canadians commonly call it — is one of the most practical kitchen upgrades you can make. It grinds food scraps into tiny particles that wash safely through your plumbing, keeping your kitchen cleaner, reducing odours, and cutting down on household waste.
But if you are a Montreal homeowner, you probably have questions: Is a garburator even legal here? How much does it cost? Which brand should I pick? And should you DIY or hire a pro?
This comprehensive guide covers everything you need to know about garbage disposal installation in Montreal — from costs and top-rated models to Quebec regulations and what to expect on installation day. Whether you are replacing an old unit or adding one for the first time, we have you covered.

Are Garbage Disposals Legal in Montreal?
Yes — garbage disposals are legal in Montreal. This is one of the most common questions we receive, and for good reason. Several major Canadian cities have banned garburators, including Toronto, Ottawa, Markham, and Guelph. Vancouver and Calgary actively discourage their use.
However, Montreal has not enacted a ban. Licensed plumbers across the Greater Montreal Area, including our team at Plumbing Montreal, regularly install garburators in residential homes. That said, there are some important caveats:
What Montreal Homeowners Should Know
- Garburators are not banned in Montreal or most of Quebec as of 2026.
- Condominiums and apartment buildings may have building-specific bylaws that restrict installation — always check with your condo syndicate or landlord first.
- Homes connected to a septic system should use septic-safe models only, as food waste increases the load on the system.
- Quebec’s Régie du bâtiment du Québec (RBQ) regulates plumbing work — installation should be performed by a CMMTQ-certified plumber.
- The City of Montreal encourages composting as the preferred method of food waste disposal, but does not prohibit garburators.
Garbage Disposal Installation Cost in Montreal (2026)

7 Benefits of Installing a Garbage Disposal
Here is why thousands of Montreal homeowners are adding garburators to their kitchens:
Reduces Kitchen Odours
Food scraps go down the drain instantly instead of sitting in your trash can for days.
Prevents Drain Clogs
Grinding food into fine particles prevents the blockages that lead to costly drain cleaning calls.
Reduces Household Waste
Less organic waste in the garbage means fewer trash bags, less mess, and fewer pest issues.
Faster Cleanup After Meals
Scrape plates directly into the sink — no scraping into the trash or sorting needed.
Discourages Pests
Eliminates exposed food waste that attracts fruit flies, ants, and rodents — especially during Montreal’s humid summers.
Works With Existing Plumbing
Modern garburators install seamlessly with standard kitchen sink and faucet setups.
Increases Kitchen Appeal
A modern garburator is a small upgrade that adds noticeable convenience — a real selling point during a kitchen or bathroom renovation.
Best Garbage Disposal Models for Montreal Homes (2026)
After researching the top-rated models from consumer testing labs and professional plumber recommendations, here are the best garburators available in Canada:
💡 Plumber’s Recommendation: For most Montreal households, the InSinkErator Evolution Compact (¾ HP) offers the best balance of power, quiet operation, and price. If noise is a top priority — especially in open-concept kitchens — upgrade to the Evolution Excel.
Continuous Feed vs Batch Feed Garbage Disposals
There are two types of garburators, and which one you choose affects both cost and daily usage:
🔄 Continuous Feed
The most popular type. Operates continuously with a wall switch — feed scraps while it runs.
- Pros: Convenient, fast, handles large volumes
- Cons: Slightly higher risk if hands go near opening
- Cost: $75–$550 for the unit
- Best for: Most households, active cooks
🔒 Batch Feed
Only activates when the drain stopper/cover is in place. Grinds one “batch” at a time.
- Pros: Safer (covered during operation), no wall switch needed
- Cons: Slower, can not add scraps while running
- Cost: $100–$400 for the unit
- Best for: Families with young children, safety-conscious homes
How to Choose the Right Horsepower for Your Home
Motor size directly impacts performance, noise level, and price. Here is a sizing guide based on household size:
A higher-HP motor also jams less frequently and typically lasts longer — important considerations for busy Montreal kitchens where the garburator sees daily use. If you are unsure which size is right for your home, our installation specialists can assess your kitchen setup and recommend the ideal model during a free consultation.
Keep in mind that motor size also impacts noise. Budget models with ⅓–½ HP tend to be significantly louder than premium ¾–1 HP units with built-in sound insulation. If your kitchen opens directly into the living or dining area — as in many Montreal condos and open-concept renovations — investing in a quieter model pays off in daily comfort.

What to Expect During Garbage Disposal Installation
Here is the step-by-step process when our garbage disposal installation team arrives at your Montreal home:
Inspection & Assessment
The plumber inspects your sink, under-cabinet space, existing plumbing, and electrical setup. If it is a first-time install, they will determine if a new GFCI outlet or dedicated circuit is needed.
Remove Old Unit (If Replacing)
The existing garburator is disconnected from the sink, plumbing, and electrical supply, then removed. The mounting area is cleaned and inspected for damage.
Install Sink Flange & Mounting Assembly
A new sink flange is seated with plumber’s putty to ensure a watertight seal. The mounting ring is secured beneath the sink to hold the disposal unit.
Mount the Garbage Disposal
The disposal unit is connected to the mounting assembly and locked into place. If you have a dishwasher, the plumber connects the dishwasher drain line to the disposal’s inlet.
Connect Plumbing & Electrical
The discharge tube is connected to the drain trap and the unit is plugged in or hardwired to a GFCI-protected outlet. All connections are tightened and secured.
Test & Walkthrough
Water is run through the system while the disposal operates to check for leaks, vibration, and proper grinding. You will receive guidance on safe use, what foods to avoid, and basic maintenance.
The entire process typically takes 1–2 hours for a standard replacement, or 2–3 hours for a first-time installation requiring new electrical work.
DIY vs Professional Garbage Disposal Installation
While some homeowners tackle garburator replacement as a DIY project, there are important reasons to consider hiring a licensed plumber — especially in Quebec:
❌ Risks of DIY Installation
- Plumbing leaks that cause water damage
- Improper electrical connections (shock hazard)
- Voided manufacturer warranty
- Not compliant with Quebec building codes
- No recourse if something goes wrong later
✅ Benefits of Professional Install
- Proper plumbing and electrical connections
- Code-compliant work (Quebec Construction Code)
- Warranty remains intact
- Leak testing and verification included
- Takes 1–2 hours — less time than most DIY attempts
⚠️ Important: In Quebec, plumbing work that involves modifying drain lines or connecting new fixtures should be performed by a CMMTQ-certified plumber. First-time installations — which involve new plumbing and electrical connections — always require professional installation.
Garbage Disposal Maintenance Tips to Extend Lifespan
A well-maintained garburator lasts 8–12 years. Follow these tips to keep yours running smoothly:
✅ DO This
- Always run cold water while operating
- Grind ice cubes monthly to clean the chamber
- Use lemon or citrus peels to freshen
- Run the disposal regularly (even if minimal waste)
- Cut large scraps into smaller pieces first
❌ NEVER Do This
- Never pour grease, oil, or fat down the drain
- Avoid fibrous foods: celery, corn husks, artichokes
- No pasta, rice, or bread (they expand and clog)
- Never put bones, shells, or pits in basic models
- Never put your hand inside the unit — use tongs
If your garburator jams, starts leaking, or makes unusual noises, do not ignore it. A quick plumbing repair call can prevent bigger issues. For ongoing kitchen plumbing health, consider booking an annual plumbing maintenance checkup.
One of the most common garburator problems in Montreal homes is clogged drain lines caused by improper use. Grease, oil, and starchy foods are the top offenders. When these substances combine with Montreal’s moderately hard water (around 116 ppm), they form stubborn blockages that require professional drain cleaning to resolve. Pairing your garburator with a water softener can help reduce mineral buildup in your kitchen pipes.
Another helpful habit is running the disposal with cold water for 15–20 seconds after grinding is complete. Cold water solidifies any remaining grease, allowing it to be chopped up rather than coating the inside of your drain pipes. For homes that experience frequent plumbing emergencies related to kitchen drains, a garburator upgrade combined with proper usage habits can significantly reduce these occurrences.
Frequently Asked Questions: Garbage Disposal Installation Montreal
Are garbage disposals (garburators) legal in Montreal?
Yes. Unlike Toronto and Ottawa, Montreal has not banned garburators. They are legal for residential use. However, individual condominium buildings may have their own rules, so check with your condo syndicate before installing one in an apartment or condo.
How much does garbage disposal installation cost in Montreal?
Total costs range from $250 to $650 CAD depending on whether you are replacing an existing unit or installing one for the first time. This includes the garburator unit ($100–$400) and professional labour ($150–$300). First-time installs requiring electrical work cost more.
What is the best garbage disposal brand for Montreal homes?
InSinkErator is the most trusted brand, with the Evolution Compact (¾ HP) being the best all-around choice for most households. Waste King offers excellent value with lifetime warranties, and Moen’s GX series is ideal for compact kitchens. All three brands are available at Montreal retailers.
How long does garbage disposal installation take?
A straightforward replacement takes 1–2 hours. A first-time installation — requiring new mounting hardware, plumbing connections, and potentially a new electrical outlet — takes 2–3 hours.
Can I install a garbage disposal myself?
Replacing an identical model with existing wiring and plumbing in place is possible for experienced DIYers. However, first-time installations, electrical work, and plumbing modifications should always be done by a CMMTQ-certified plumber to ensure code compliance and safety in Quebec.
What foods should never go in a garbage disposal?
Avoid grease, oil, and fats (they solidify and clog pipes). Also avoid fibrous foods like celery, corn husks, and artichokes. Starchy foods like pasta, rice, and bread expand with water and cause blockages. Bones and shells should only go in ¾ HP or higher models, and only in small quantities.
How long does a garbage disposal last?
With proper use and maintenance, most garburators last 8–12 years. Signs it is time to replace include persistent jamming, frequent leaks, foul odours that cleaning cannot fix, and loud grinding noises. If repairs exceed 50% of replacement cost, installing a new unit is the better investment.
Do I need a special electrical outlet for a garbage disposal?
Yes. Garburators require a 120-volt, 15-amp circuit with GFCI protection. Many Montreal kitchens already have a suitable outlet under the sink. If not, an electrician will need to install one, which typically adds $100–$200 to the project.
Can I use a garbage disposal with a septic system?
You can, but it is not generally recommended. Food waste increases the load on your septic system and may require more frequent pump-outs. If you choose to install one, use a septic-safe model like the InSinkErator Evolution Septic Assist, which injects enzymes to help break down food waste.

Yes! Plumbing Montreal provides professional garburator installation and replacement across Montreal, Laval, the West Island, South Shore, and surrounding areas. We install all major brands including InSinkErator, Waste King, and Moen. Call (514) 316-9154 for a free estimate.
