PLUMBING COSTS IN THE GTA: $500 to $35,000+ 
Plumbing is the trade scope that most frequently produces budget surprises in GTA renovation — because the visible plumbing (fixtures, faucets, and finishes) is the least expensive part of the scope, and the behind-the-wall and below-slab work that determines whether the system functions correctly is the most expensive and the least visible. At Maple Leaf Quality Renos, all plumbing is performed by licensed Ontario plumbers with plumbing permits obtained and inspected on every project. No unlicensed plumbing is performed on any scope we deliver. 

What affects GTA plumbing cost: 

• Whether fixtures stay in existing positions or are relocated — retaining existing drain and supply positions is significantly less expensive than relocating them; moving a toilet, a shower drain, or a kitchen sink requires accessing and modifying the drain stack connections
• Whether slab cutting is required — GTA main floor bathrooms above a concrete slab require cutting the concrete to access or relocate drain connections; this is a significant cost driver
• The age and condition of existing supply lines — galvanized steel supply lines in pre-1980 GTA homes are frequently at end of life; a renovation that opens the walls is the appropriate time to replace them
• The scope of new fixture additions — adding a bathroom to a space that did not previously have one is significantly more expensive than renovating an existing bathroom in place

ELECTRICAL COSTS IN THE GTA: $500 to $25,000+ 

Electrical work in a GTA renovation is one of the two trade scopes (along with plumbing) where the permit requirement is absolute and the consequences of unlicensed work are the most severe — insurance voidance, fire hazard, and failed ESA inspections that require opening completed walls. At Maple Leaf Quality Renos, all electrical work is performed by licensed Ontario electricians with ESA permits obtained and inspected on every project. 

What affects GTA electrical cost: 

• Whether the existing panel has adequate capacity — a 100-amp panel in a typical pre-1980 GTA home is frequently at capacity; a kitchen renovation that adds dedicated appliance circuits typically requires a 200-amp panel upgrade before the new circuits can be added
• Whether knob-and-tube wiring is present — pre-1950 GTA homes frequently have knob-and-tube wiring that insurance companies will not cover; a renovation that opens the walls is the appropriate time to replace it
• The number of new circuits required — each dedicated appliance circuit, each new lighting zone, and each GFCI-protected outlet zone is a separate circuit from the panel to the device location
• The distance from the panel to the work location — a basement renovation in a home where the panel is at the opposite end of the basement requires longer wire runs than a kitchen renovation adjacent to the panel

 
Current GTA electrical costs by scope: 

Panel and Service 

• 200-amp electrical panel upgrade (from 100-amp): $2,500 to $4,500 supply and installation including ESA permit and inspection
• Sub-panel installation (basement or garage): $1,200 to $2,800 supply and installation
• Knob-and-tube wiring replacement (full house): $12,000 to $25,000 depending on home size and access

HVAC COSTS IN THE GTA: $1,500 to $35,000+ 

HVAC — heating, ventilation, and air conditioning — is the renovation scope that most consistently affects daily comfort, energy cost, and indoor air quality for the life of the home. All gas-fired HVAC work at Maple Leaf Quality Renos is performed by TSSA-registered gas contractors. All ductwork and ventilation modifications are coordinated with the electrical and plumbing scopes before walls are closed. 

What affects GTA HVAC cost: 

• System type — forced-air furnace with central AC is the most common GTA system; ductless mini-splits, heat pumps, and in-floor radiant are alternatives with different cost and performance profiles
• Home size and existing ductwork condition — a larger home requires a higher-capacity system; deteriorated or undersized ductwork requires modification in addition to equipment replacement
• Ductwork modifications — a basement renovation, an open-concept conversion, or an addition that changes the home's thermal zones may require ductwork extension, resizing, or rebalancing
• Energy efficiency specification — a high-efficiency furnace (96+ AFUE) costs more upfront but delivers meaningfully lower operating costs over its service life in Ontario's heating-dominated climate
• Fuel type — natural gas is the most common GTA residential fuel; heat pump systems eliminate gas heating operating costs and qualify for significant federal and provincial rebates

 
Furnace

Natural gas furnaces are the primary heating system in the vast majority of GTA homes. Replacement is the right decision when the existing furnace is more than 15 to 20 years old, requiring frequent repairs, or operating at below-standard efficiency. 

Current GTA furnace replacement costs: 

• Mid-efficiency natural gas furnace (80 AFUE, supply and installation): $3,500 to $5,500
• High-efficiency natural gas furnace (96+ AFUE, supply and installation): $4,500 to $7,500; qualifies for Enbridge and federal rebate programs
• Furnace with humidifier and air filtration upgrade: $5,500 to $9,500
• Ductwork modification (where required by renovation scope): add $1,500 to $6,000

 
Central Air Conditioning 

Central air conditioning in the GTA is a comfort essential from May through September and a meaningful resale consideration for buyers evaluating properties without it. 

Current GTA central AC costs:

• Central AC replacement (existing ductwork, supply and installation): $3,500 to $6,500
• Central AC new installation (home without existing AC): $5,000 to $9,000 including refrigerant line and electrical connection
• High-efficiency central AC (20+ SEER rating): $6,000 to $11,000; qualifies for federal and provincial rebate programs
• Combined furnace and AC replacement (mid-efficiency): $7,500 to $14,000
• Combined furnace and AC replacement (high-efficiency): $10,000 to $18,000

 
Heat Pump Systems 

Heat pumps are the fastest-growing HVAC category in the GTA — driven by federal and provincial rebate programs that significantly offset higher equipment costs and by the dual heating and cooling function that eliminates the need for a separate furnace and air conditioner. 

Current GTA heat pump costs: 

• Air-source heat pump (replacing existing AC, works with gas furnace below -15°C): $5,500 to $10,000
• Cold-climate air-source heat pump (effective to -30°C, replaces gas furnace entirely): $8,000 to $16,000
• Canada Greener Homes Grant — up to $6,500 available for qualifying heat pump installations; confirm current program status at canada.ca/greener-homes
• Enbridge Gas and local utility rebates — additional rebates available for high-efficiency equipment; confirm current amounts at the equipment selection stage

 
Ductless Mini-Split Systems 

A ductless mini-split — a wall-mounted indoor unit connected by refrigerant lines to an outdoor compressor — is the most cost-effective way to add independent heating and cooling to a space not served by the existing duct system, including legal basement suites, home additions, and converted garages. 

Current GTA mini-split costs: 

• Single-zone mini-split (one indoor unit, supply and installation): $3,500 to $6,500
• Multi-zone mini-split (two to four indoor units, one outdoor compressor): $6,500 to $14,000
• Legal basement suite mini-split — provides the independent temperature control required by the Ontario Building Code for a secondary dwelling unit: $3,500 to $6,500
• ESA electrical permit — required for all mini-split installations; a dedicated 240-volt circuit from the panel is mandatory

 
Ductwork Ductwork modifications are required whenever a renovation changes the home's thermal zones — including basement finishing, open-concept conversions, and home additions. 

Current GTA ductwork costs: 

• Ductwork extension to finished basement (new supply and return runs): $1,500 to $4,500 depending on register count and run distance
• Ductwork rebalancing after open-concept conversion: $800 to $2,500
• New ductwork installation (home without existing ductwork): $6,000 to $14,000
• Duct sealing and insulation (basement or attic): $1,500 to $4,000
• HRV (Heat Recovery Ventilator) installation — provides controlled fresh air exchange while recovering heat from exhaust air; required for all new residential construction and strongly recommended for legal suite construction: $2,500 to $5,000

 
Ventilation 

Ventilation modifications are required in every kitchen renovation, bathroom renovation, and basement finishing scope — and are one of the most frequently missed line items in contractor estimates. 

Current GTA ventilation costs: 

• Kitchen range hood venting to exterior (new duct penetration and cap): $400 to $1,200 depending on run length and wall construction
• Bathroom exhaust fan replacement (vented to exterior, ESA permit required): $250 to $600 supply and installation
• Bathroom exhaust fan with humidity sensor: $350 to $750 supply and installation
• Dryer vent installation or replacement to exterior: $200 to $500

 
HVAC Permit and Compliance Requirements 

All HVAC work at Maple Leaf Quality Renos is performed in full compliance with Ontario trade licensing and permit requirements: 

• TSSA registration — all gas-fired equipment must be installed by a TSSA-registered gas contractor in Ontario; this is a legal requirement; confirm TSSA registration before any gas contractor begins work on your property
• ESA electrical permit — required for all new electrical connections to HVAC equipment including mini-splits, heat pumps, HRVs, and new thermostat circuits; managed in-house through our licensed electricians
• Building permit — required for new HVAC system installations in some GTA municipalities; confirmed at the design stage before any work begins
