Gas Range Repair & Safety Guide Toronto: Regulations, Enbridge, Common Issues

Gas ranges offer precise temperature control and instant heat, making them preferred by serious home cooks across Toronto. However, gas appliances come with unique safety requirements, strict regulatory compliance, and repair considerations that electric ranges don't have. This comprehensive guide covers Toronto-specific gas regulations, Enbridge Gas requirements, TSSA certification standards, common gas range problems with repair costs, safety protocols, and when you absolutely must call a certified professional versus simple troubleshooting you can safely perform yourself.

Toronto Gas Appliance Regulations & Requirements

Toronto has some of North America's strictest gas appliance regulations, governed by multiple agencies with overlapping jurisdictions. Understanding these requirements prevents legal issues, insurance complications, and safety hazards.

Technical Standards & Safety Authority (TSSA)

The TSSA is Ontario's gas safety regulator with legal authority over all gas work in Toronto:

TSSA certification requirements:

• Who needs certification: Anyone performing work on gas lines, gas appliance connections, gas valve repairs, or gas burner adjustments
• What doesn't require certification: Replacing electric igniters (if no gas connection work), cleaning burners, replacing knobs/grates (cosmetic work only), replacing oven racks
• Certification types:
  • Gas Fitter 2 (G2): Can work on small gas appliances, residential ranges, dryers, fireplaces
  • Gas Fitter 3 (G3): More extensive commercial and residential work
• Verification: Ask for TSSA license number, verify at tssa.org/license-lookup
• Penalties for unlicensed work: $50,000+ fines, criminal charges if injury/death occurs, complete loss of insurance coverage

TSSA inspection requirements:

• New gas range installation requires TSSA inspection and approval
• Gas line modifications require permit and inspection
• Conversions (natural gas to propane or vice versa) require certification from licensed gas fitter
• Inspection costs: $100-150 for basic residential inspection

Enbridge Gas Requirements

Enbridge Gas is Toronto's natural gas utility provider with specific requirements for customers:

Gas meter and supply line:

• Enbridge owns and maintains gas meter and supply line up to meter outlet
• Homeowner responsible for all gas lines and appliances downstream of meter
• Clear access to meter required (36-inch clearance minimum)
• Snow removal around meter is homeowner responsibility

Emergency response:

• Gas leak hotline: 1-866-763-5427 (24/7/365)
• Enbridge responds within 45 minutes for emergency calls
• Service is free for gas leaks and emergencies
• Enbridge will shut off gas and tag appliance if unsafe

Appliance requirements:

• Only CSA-certified (Canadian Standards Association) gas ranges allowed
• Ranges must be converted for natural gas (most come configured for propane)
• Conversion must be documented with TSSA paperwork

Ontario Building Code (OBC) Requirements

The OBC mandates specific safety requirements for gas ranges in Toronto homes:

Ventilation requirements:

• Range hood or exhaust fan required over gas cooktop (Code 9.32.3.3)
• Minimum exhaust capacity: 100 CFM (cubic feet per minute) for standard range
• Hood must vent to exterior (recirculating hoods not code-compliant for gas)
• Replacement air required for exhaust over 400 CFM

Clearance requirements:

• 18-inch minimum clearance from range top to combustible materials (cabinets, wood range hood)
• 30-inch minimum clearance to unprotected combustibles overhead
• 6-inch clearance from sides of range to combustible walls
• Fire-rated materials allow reduced clearances (check manufacturer specs)

Carbon monoxide detection:

• CO detector required within 15 feet of gas range (OBC 9.32.3.10)
• Detector must be hardwired or have 10-year sealed battery
• Combination smoke/CO detectors acceptable
• Penalty for non-compliance: $50,000 fine, liability if CO poisoning occurs

Insurance Implications

Toronto homeowners insurance has specific exclusions related to gas appliances:

• Unlicensed gas work voids ALL coverage: If fire, explosion, or CO poisoning results from unlicensed gas work, insurance denies entire claim - not just gas damage, but all related damage including structural, medical, liability
• Required documentation: Keep receipts from TSSA-certified gas fitters for all gas appliance work
• Disclosure requirement: Must disclose gas range age and repair history when selling property
• Rental properties: Landlords must provide annual gas appliance inspection certificate to tenants (Residential Tenancies Act requirement in many municipalities)

Common Gas Range Problems & Repair Costs

Understanding common gas range issues, their causes, and repair costs helps you make informed decisions about service calls and appliance longevity.

Problem #1: Burner Won't Light (Igniter Failure)

Symptoms: Clicking sound but no flame, or no clicking at all; works with match but not with igniter; some burners light while others don't

Cause breakdown:

• Weak or failed igniter (70% of cases): Ceramic igniter degrades over time from heat stress, moisture, and food spills. Typical lifespan: 4-7 years with regular use
• Moisture in igniter (15%): Boil-overs and cleaning water shorts igniter temporarily. Usually resolves after drying 24-48 hours
• Clogged burner ports (10%): Food debris blocks gas flow, preventing ignition even with working igniter
• Faulty spark module (5%): Electronic control that powers multiple igniters fails, affecting all burners simultaneously

DIY troubleshooting (SAFE - no gas work):

1. Clean burner caps and ports (15 minutes):
   • Turn off gas supply at range shutoff valve
   • Remove burner caps and grates
   • Use soft brush to clean burner ports (small holes where flame emerges)
   • Wipe igniter with dry cloth (never use water while cleaning igniter)
   • Ensure burner caps seat properly when reinstalling (misalignment prevents ignition)
   • Turn gas back on and test
2. Check for moisture (5 minutes):
   • If burner won't light after spill/cleaning, wait 24 hours for complete drying
   • Place fan near range to accelerate drying
   • Test after drying period
3. Test igniter continuity (if you have multimeter - 10 minutes):
   • Turn off gas and unplug range
   • Locate igniter wire connection behind cooktop
   • Test resistance (should be 50-400 ohms typically)
   • Infinite resistance = failed igniter

Professional repair costs (Toronto):

When to call professional: If cleaning doesn't resolve issue, igniter replacement requires professional. While technically DIY-able for electric igniters (no gas work), most homeowners prefer professional service for warranty and proper diagnosis of spark module vs individual igniter issues.

Problem #2: Weak or Yellow Flames

Symptoms: Flames are yellow/orange instead of blue; flames are smaller than usual; uneven flame pattern; soot marks on cookware bottoms

Cause breakdown:

• Clogged burner ports (40%): Food debris restricts gas flow, causing incomplete combustion and yellow flames
• Air shutter misadjustment (30%): Burners have adjustable air shutter controlling air/gas mixture. Incorrect setting causes yellow flames
• Low gas pressure (20%): Enbridge supply issue or regulator problem reduces gas pressure below required 5-7 inches water column (Toronto natural gas standard)
• Wrong gas type (10%): Natural gas range connected to propane or vice versa without proper conversion. This is dangerous and requires immediate professional correction

DIY troubleshooting (SAFE):

1. Clean burner thoroughly: Follow cleaning process described in Problem #1. Pay special attention to burner ports
2. Check flame color after cleaning:
   • Proper flame: Blue with small yellow tip, 1-2 inch height, steady cone shape
   • Improper flame: Mostly yellow/orange, flickering, lifting off burner, very small

Professional repair costs:

DANGER SIGNS - Call professional immediately:

• All burners suddenly turn yellow (indicates pressure problem or wrong gas type)
• Flames lift off burner (flashback hazard)
• Flames extend beyond burner cap
• Strong gas odor when burners are on
• Soot accumulation on cookware or range hood

Yellow flames indicate incomplete combustion, which produces carbon monoxide. This is a serious safety issue requiring immediate professional attention.

Problem #3: Oven Won't Heat or Heats Unevenly

Symptoms: Oven doesn't reach set temperature; temperature fluctuates during cooking; hot spots or cold spots; pilot light won't stay lit (on older models)

Cause breakdown:

• Faulty oven igniter (50%): Most common gas oven problem. Igniter must draw sufficient amperage to open gas valve - weak igniter never opens valve even if it glows
• Bad temperature sensor (25%): Thermocouple or RTD sensor sends incorrect temperature reading to control board
• Failed gas valve (15%): Valve that controls gas flow to oven burner sticks closed or open
• Control board failure (10%): Electronic control fails to send signal to igniter or gas valve

DIY diagnosis (SAFE):

1. Watch igniter behavior (5 minutes):
   • Turn on oven and watch igniter through oven door window
   • Normal: Igniter glows bright white/orange for 30-90 seconds, then gas ignites with small "whoosh" sound
   • Weak igniter: Glows dim orange but never opens gas valve (no whoosh, no flame)
   • Failed igniter: Doesn't glow at all
2. Test oven temperature accuracy (90 minutes):
   • Place oven thermometer in center of oven
   • Preheat to 350°F
   • Wait 20 minutes after preheat signal
   • Check thermometer reading
   • Acceptable range: ±25°F (325-375°F)
   • If outside range: sensor or calibration issue

Professional repair costs:

Problem #4: Gas Smell When Operating

IMMEDIATE ACTION REQUIRED - This is emergency situation:

1. If strong gas smell (rotten eggs/sulfur):
   • Evacuate immediately - don't stop to gather belongings
   • Don't turn lights on/off, use phone, or create any spark/ignition source
   • Leave door open while evacuating
   • Call 911 and Enbridge (1-866-763-5427) from outside, away from house
   • Don't re-enter until emergency services clear building
2. If faint gas smell only when burner ignites (brief):
   • This is semi-normal - brief gas release before ignition
   • However, should be very faint and dissipate in 1-2 seconds
   • If smell persists more than 5 seconds after ignition, or smell intensifies over time, call professional for inspection

Possible causes (professional diagnosis required):

• Leaking gas connection to range
• Cracked burner casting
• Loose or damaged supply line
• Faulty gas valve seals
• Improper installation

Professional inspection/repair costs:

Gas Safety Protocols & Carbon Monoxide Prevention

Proper gas range flame should be blue with small yellow tips. Yellow or orange flames indicate incomplete combustion and require immediate professional service to prevent carbon monoxide risks.

Recognizing Gas Leaks

Natural gas is odorless, so Enbridge adds mercaptan (sulfur compound) to create distinctive smell. Learn to identify gas leaks:

Signs of gas leak:

• Smell: Rotten eggs, sulfur, skunk-like odor (distinctive and unmistakable once you've smelled it)
• Sound: Hissing, whistling, or roaring noise near gas line or appliance
• Sight: Dead vegetation in line of buried gas pipe, dust blowing from ground, bubbles in standing water
• Physical: Dizziness, nausea, headache, fatigue (from breathing gas - these are late-stage symptoms requiring immediate evacuation)

Common leak locations:

• Flexible gas connector behind range (crimped, punctured, or degraded)
• Shut-off valve connection (loose fitting)
• Burner gas orifices (cracked casting)
• Pilot light assemblies on older ranges
• Gas valve to burner connections inside range

Carbon Monoxide (CO) Awareness

Carbon monoxide is silent killer - odorless, colorless, tasteless gas produced by incomplete combustion. Gas ranges can produce CO if improperly adjusted or maintained.

CO sources from gas ranges:

• Yellow flames (incomplete combustion)
• Clogged burner ports restricting air intake
• Blocked ventilation preventing exhaust removal
• Range hood not functioning or not vented to exterior
• Running oven continuously for heat (never use range as heating source)

CO poisoning symptoms:

• Low-level exposure: Headache, dizziness, weakness, upset stomach, vomiting, chest pain, confusion (often mistaken for flu)
• High-level exposure: Severe headache, mental confusion, loss of muscle coordination, loss of consciousness, death
• Chronic low-level exposure: Memory problems, difficulty concentrating, mood changes

CO detector requirements (Ontario Building Code):

• CO detector within 15 feet of gas range
• Detector on every floor of home
• Hardwired or 10-year sealed battery unit required
• Test monthly, replace per manufacturer guidelines (typically 5-10 years)
• If CO alarm sounds: Evacuate, call 911 from outside, don't re-enter until cleared

Proper Ventilation

Adequate ventilation is critical for gas range safety:

Range hood requirements:

• 100 CFM minimum exhaust capacity for standard 30-inch range
• 150 CFM for high-BTU burners (15,000+ BTU)
• Must vent to exterior (not recirculate) per Ontario Building Code
• Duct should be shortest, straightest path to exterior
• Clean grease filters monthly
• Professional duct cleaning every 1-2 years

Signs of inadequate ventilation:

• Lingering cooking odors (gas combustion byproducts not being removed)
• Excessive moisture/condensation on windows while cooking
• Soot on walls or ceiling above range
• Pilot light (on older ranges) frequently goes out
• Family members experience headaches or flu-like symptoms while cooking

Annual Maintenance & Inspection

Professional annual inspection is best practice for gas range safety, though not legally mandated for residential properties in Toronto (required for multi-unit residential and commercial).

Professional Inspection Checklist

TSSA-certified gas fitter should inspect:

• Gas connections: Check for leaks using soap solution or electronic sniffer, verify proper torque on fittings, inspect flexible connector for cracks/damage
• Burner operation: Test ignition on all burners, verify proper flame color (blue with small yellow tip), check flame height and pattern, clean and adjust air shutters
• Oven performance: Verify oven reaches and maintains temperature, test igniter and safety valve operation, check door seal integrity
• Gas pressure: Measure supply pressure (should be 5-7 inches water column for Toronto natural gas), verify pressure at manifold
• Ventilation: Verify range hood operation, check exhaust duct for obstructions, confirm exterior vent cap opens properly
• Combustion quality: Use combustion analyzer to measure CO levels (should be under 100 ppm), check oxygen levels in exhaust
• Safety devices: Test automatic shutoff systems if equipped, verify proper operation of flame failure devices on older units

Professional inspection cost (Toronto): $150-$220, includes written report and recommendations

Monthly Homeowner Maintenance

Between annual professional inspections, homeowners should perform basic maintenance:

• Clean burners (monthly - 15 minutes):
  • Turn off gas at shutoff valve
  • Remove grates and burner caps
  • Clean ports with soft brush
  • Wipe spills from cooktop
  • Ensure burner caps seat properly when reinstalling
• Check flame color (monthly - 5 minutes):
  • Light each burner
  • Verify blue flames with minimal yellow tips
  • If flames are mostly yellow, call for professional service
• Clean range hood filters (monthly - 10 minutes):
  • Remove metal mesh filters
  • Soak in hot water with dish soap or degreaser
  • Scrub with soft brush
  • Rinse thoroughly and dry completely before reinstalling
• Test CO detector (monthly - 2 minutes):
  • Press test button on detector
  • Verify alarm sounds
  • If doesn't work or battery low warning chirps, replace immediately
• Visual inspection (monthly - 5 minutes):
  • Check flexible gas connector behind range for kinks, cracks, or damage
  • Look for signs of gas leak (listen for hissing, smell for gas)
  • Verify range hood light and exhaust fan work

When to Repair vs Replace Your Gas Range

Use these guidelines to determine whether repair makes financial sense:

Repair if:

• Range is under 8 years old
• Repair cost is under 50% of replacement cost
• Only single component failure (igniter, sensor, valve)
• Range is high-quality brand (Wolf, Viking, Thermador, BlueStar, Miele)
• You're satisfied with range performance and features
• No history of multiple repairs

Example (REPAIR): 5-year-old high-end gas range (originally $2,500, comparable replacement $2,800 today). Failed oven igniter. Repair quote: $240. Calculation: $240 ÷ $2,800 = 8.5% of replacement cost. Decision: REPAIR

Replace if:

• Range is over 15 years old
• Repair cost exceeds 50% of replacement cost
• Multiple component failures
• Safety concerns (cracked burner castings, unrepairable gas leaks)
• Obsolete parts (manufacturer discontinued, parts unavailable)
• You want improved features (convection, higher BTU burners, better controls)

Example (REPLACE): 16-year-old mid-range gas range. Multiple issues: failed oven igniter, worn burner valves, damaged burner castings. Repair estimate: $680. Comparable new range: $1,100 installed. Calculation: $680 ÷ $1,100 = 62% of replacement cost, plus range is past typical lifespan. Decision: REPLACE

Toronto Replacement Cost Breakdown

Installation includes: Disconnecting old range, TSSA-certified gas connection of new range, testing for leaks, disposal of old range. Some installers include permit in installation cost, others charge separately.

Frequently Asked Questions

Can I repair my gas range myself in Toronto?

No - DIY gas appliance work is ILLEGAL in Ontario and voids all insurance coverage. Only TSSA-certified gas fitters (Technical Standards & Safety Authority) can legally work on gas ranges, connections, valves, or lines. Penalties for unlicensed gas work: $50,000+ fines, criminal charges if injury occurs, complete loss of insurance coverage. You CAN safely clean burners, replace grates/knobs (cosmetic parts), and replace electric igniters if no gas connection work needed. Anything involving gas lines, gas valves, or gas pressure adjustments requires TSSA certification. Verify technician license at tssa.org/license-lookup. DIY electrical repairs on range are legal but gas work is not.

What should I do if I smell gas from my stove in Toronto?

STRONG gas smell (rotten eggs/sulfur): Evacuate immediately, don't use lights/phones/switches inside, leave door open, call 911 and Enbridge (1-866-763-5427) from outside. Don't re-enter until cleared. FAINT smell only during ignition (1-2 seconds): Semi-normal, but call for inspection if persists 5+ seconds or worsens over time. Never ignore gas smell - natural gas is explosive and causes asphyxiation. Enbridge responds to emergency calls within 45 minutes (free service). After evacuation, stay 50+ feet from building until emergency services arrive. If you evacuated at night, don't re-enter for belongings - possessions are replaceable, you're not. Toronto Fire Services will clear building and ventilate if necessary.

How much does gas range repair cost in Toronto?

Average gas range repair in Toronto: $180-$320. Common repairs: Igniter replacement $120-180 (most common, 30-45 min), burner valve $150-220 (45-60 min), oven thermostat $180-280 (60-90 min), gas valve assembly $280-430 (90-120 min), control board $330-530 (60-90 min). Diagnostic fee $85-120, usually waived with repair. Cost factors: Part brand (GE/Samsung cheaper than Wolf/Viking), labor rates vary by company, TSSA-certified gas fitters command premium pricing. Get 2-3 quotes for major repairs. Emergency/after-hours service adds $50-100. Prevention saves money: annual inspection $150-220 catches problems early. Repair makes sense if under 50% replacement cost and range under 8 years old.

Do I need TSSA certification to work on gas ranges in Toronto?

Yes - TSSA (Technical Standards & Safety Authority) certification is legally required for any work on gas appliances in Ontario. Required for: gas line connections, gas valve repairs, gas pressure adjustments, burner air shutter adjustment if it involves gas flow, conversion between natural gas and propane. NOT required for: cleaning burners, replacing electric igniters (if no gas connection work), replacing knobs/grates, replacing oven racks. TSSA certification types: Gas Fitter 2 (G2) can work on residential ranges/dryers/fireplaces, Gas Fitter 3 (G3) for more extensive work. Verify license at tssa.org/license-lookup. Using unlicensed technician voids ALL insurance coverage, not just gas damage. Penalties: $50,000+ fines, criminal liability if incident causes injury/death.

How often should I have my gas range inspected in Toronto?

Annual professional inspection recommended for safety, though not legally mandated for single-family homes in Toronto (required for multi-unit residential and commercial). Annual inspection by TSSA-certified gas fitter includes: gas leak testing, burner adjustment, flame quality check, gas pressure measurement, ventilation verification, combustion analysis (CO levels), written safety report. Cost: $150-220. Between professional inspections, monthly homeowner maintenance: clean burners, check flame color (should be blue), clean range hood filters, test CO detector. Call for inspection immediately if: yellow flames, gas smell, burners won't light, soot on cookware, family members experience headaches while cooking. Lifespan: gas ranges last 10-15 years with proper maintenance. Prevention is cheaper than emergency repairs.

What is the Enbridge Gas emergency number for Toronto?

Enbridge Gas 24/7 emergency hotline: 1-866-763-5427. Call immediately if: you smell gas (rotten eggs/sulfur odor), you hear gas hissing/whistling, you see damaged gas meter or supply line, you hit gas line while digging, carbon monoxide alarm sounds. Enbridge responds within 45 minutes for emergency calls (free service). Also call 911 for gas emergencies - Toronto Fire Services will respond. If you've evacuated due to gas smell, wait outside 50+ feet from building until emergency services arrive. Enbridge will shut off gas supply and "red tag" unsafe appliances. After Enbridge shuts off gas, you MUST have TSSA-certified gas fitter make repairs and get TSSA inspection before Enbridge will restore service. Don't attempt to turn gas back on yourself - illegal and dangerous.

Are yellow flames on gas range dangerous?

Yes - yellow flames indicate incomplete combustion producing carbon monoxide (CO), an odorless, deadly gas. Proper flames: Blue with small yellow tip, 1-2 inch steady cone, no flickering. Yellow flames caused by: clogged burner ports (clean with brush), incorrect air/gas mixture (air shutter adjustment by professional), low gas pressure (Enbridge or regulator issue), wrong gas type (natural gas range on propane = dangerous). Yellow flames also produce soot, reducing cooking efficiency and coating cookware. Immediate action if yellow flames: stop using range, ventilate kitchen, call TSSA-certified technician. Install CO detector within 15 feet of gas range (Ontario Building Code requirement). CO poisoning symptoms: headache, dizziness, nausea, confusion (often mistaken for flu). Don't ignore yellow flames - professional repair $100-240 vs potential death from CO exposure.

Can I convert my gas range from natural gas to propane in Toronto?

Yes, but ONLY by TSSA-certified gas fitter - DIY conversion is illegal, dangerous, and voids insurance. Conversion requires: replacement orifices (jets) sized for propane's higher pressure, air shutter adjustment, gas pressure regulator change, valve spring adjustment (on some models), TSSA inspection and approval. Toronto uses natural gas (from Enbridge), propane only in rural areas without natural gas service. Conversion cost: $230-400 parts + labor. Most ranges ship configured for propane, require conversion to natural gas for Toronto. Conversion kits available from manufacturer ($80-180). Using natural gas range with propane (or vice versa) without conversion creates: yellow flames, excessive CO production, incomplete combustion, explosion risk. Never attempt this yourself - manufacturers void warranty if DIY converted.

What are signs my gas range igniter needs replacement?

Igniter failure signs: 1) Clicking sound but no flame (igniter weak, can't open gas valve), 2) Igniter glows dim orange but doesn't ignite (insufficient amperage), 3) No clicking and no glow (complete failure), 4) Works sometimes but not others (intermittent failure), 5) Burner lights with match but not with igniter (proves gas supply fine, igniter bad). Test: Watch igniter glow when starting burner - should glow bright white/orange for 30-90 seconds then gas ignites with "whoosh." Dim orange glow that never ignites = weak igniter. Typical igniter lifespan: 4-7 years regular use. Replacement cost Toronto: $120-180 for single igniter including labor. Multiple igniters failing together indicates spark module issue ($250-360 repair). Prevention: avoid boil-overs and spills on igniter, clean burners monthly, dry igniter if wet.

Is it safe to use my oven for heat in Toronto winters?

NO - using gas oven for supplemental heat is EXTREMELY DANGEROUS and illegal under Ontario Building Code. Dangers: 1) Carbon monoxide production - running oven continuously creates deadly CO buildup, especially in tightly sealed modern homes; 2) Gas appliances aren't designed for continuous operation - creates safety system failures; 3) Oxygen depletion in room; 4) Fire risk from prolonged high temperatures; 5) Voids all insurance if causes incident. Ontario Fire Marshal has issued multiple warnings about this practice after winter deaths. If you need heat: use proper heating system, space heaters, or call City of Toronto Winter Warmth program (311) for emergency heating assistance. If furnace broken, many HVAC companies offer emergency financing. Never compromise safety to save heating costs. CO is silent killer - odorless, colorless, causes death while you sleep.

Conclusion

Gas range repair in Toronto requires strict adherence to safety regulations, TSSA certification requirements, and Enbridge Gas protocols. While gas ranges offer superior cooking performance, they come with serious safety responsibilities that electric ranges don't have. The most important takeaways:

Safety first, always:

• NEVER attempt DIY gas work - it's illegal, voids insurance, and risks death
• Only hire TSSA-certified gas fitters (verify at tssa.org/license-lookup)
• If you smell gas, evacuate and call 911 + Enbridge (1-866-763-5427) from outside
• Install CO detector within 15 feet of gas range - Ontario Building Code requirement
• Yellow flames = carbon monoxide production = immediate professional service needed

Cost-effective maintenance:

• Monthly cleaning and inspection (15-30 minutes) prevents 70% of common problems
• Annual professional inspection ($150-220) catches issues before they become expensive repairs
• Average repair $180-320 vs $1,500-3,000 range replacement
• Use 50% rule: repair if under 50% replacement cost, replace if over 50%

Toronto-specific requirements:

• TSSA certification mandatory for all gas work
• Enbridge Gas owns meter and supply line up to outlet
• New installations and conversions require TSSA inspection ($100-150)
• Range hood must vent to exterior (Ontario Building Code)
• Keep documentation from certified gas fitters for insurance and resale purposes

Gas ranges typically last 10-15 years with proper maintenance and professional service. Don't compromise safety for savings - the cost difference between DIY and professional service is negligible compared to risks of gas leak, explosion, or carbon monoxide poisoning. When in doubt, make the call to a TSSA-certified professional.
