CRA GST/HST Fireplace Cleaning, Gas Fireplace Repair & Chimney Cap Installation Audit — Montreal CPA Firm Near You: Defending Taxable Services, Parts & Materials, Subcontractors & ITCs

A CRA GST/HST Fireplace & Chimney Service Audit targets:

• gas fireplace repair technicians
• wood fireplace cleaning crews
• chimney cap installers
• chimney damper repair specialists
• pilot-light & ignition repair contractors
• seasonal fireplace tune-up providers
• mobile gas-fireplace repair crews
• subcontracted chimney/fireplace assistants

CRA audits this industry aggressively because fireplace cleaning and repair combine:

• 100% taxable services (cleaning, repair, installation)
• gas-related parts (valves, thermopiles, pilots, sensors)
• seasonal surges (fall/winter)
• safety-related work with high equipment ITCs
• cash/e-transfer revenue
• subcontract helpers with incomplete paperwork

Mackisen CPA Montreal specializes in protecting fireplace contractors through complete GST/HST compliance correction, subcontractor verification, and ITC reconstruction.

Legal Foundation

Excise Tax Act

• s.165 — ALL fireplace cleaning, repair, ignition troubleshooting & cap installation are fully taxable

• s.221 — supplier must charge GST/HST

• s.169 — ITCs allowed only with full, valid documentation

• s.141.01 — allocation for mixed-use tools, ladders & vehicles

• Schedule IX — GST/HST rate depends on the property location

• s.123(1) — defines “repair,” “installation,” “real property service”

CRA & Case Law

• Fireplace repair = taxable

• Gas ignition/pilot-light work = taxable

• Chimney cap replacement = taxable

• Cleaning = taxable

• CGI v. Canada — GST/HST based on location of serviced property

• Royal Bank v. Canada — invoice defects invalidate ITCs

• Northwest Company Inc. — supplier invoices must meet statutory requirements

Learning insight: No fireplace or chimney service is exempt — all labour, materials, and travel fees must be taxed.

Why CRA Audits Fireplace & Chimney Service Providers

Revenue Risks

• GST/HST not charged on fireplace cleaning
• ignition/pilot-light repairs billed without tax
• e-transfer payments underreported
• seasonal tune-ups not invoiced
• chimney cap installation fees missing GST
• gas-valve replacement miscoded
• multi-property service calls not matched to GST periods
• after-hours emergency repairs not taxed
• travel ladder-fee not billed or taxed

Subcontractor Risks

• gas fireplace helpers not registered for GST
• ladder crew or chimney assistants paid cash
• invalid subcontractor invoices
• missing GST numbers
• T4A non-compliance

ITC Risks

• missing receipts for:
– pilot assemblies, thermocouples, gas valves
– chimney caps, dampers, flashing
– ladders, PPE, vacuum filters
– soot vacuums, brushes, hoses
– vehicle mileage & repairs
• imported parts/tools not self-assessed
• personal-use tools mixed with business tools
• home-storage costs overclaimed

Operational Risks

• incomplete job logs (address, repair type, time)
• material usage inconsistent with repair claims
• pilot-light troubleshooting not documented
• no before/after photos
• inconsistent e-transfer descriptions
• emergency repair calls not on invoices

High-risk operators:

• gas fireplace technicians

• chimney cap installers

• mobile chimney/fireplace crews

• hybrid cleaning + repair contractors

Learning insight: CRA compares materials purchased vs jobs performed to detect underreporting.

CRA Fireplace & Chimney Audit Process

1. CRA requests:
   – invoices (cleaning, repairs, caps, parts, travel)
   – subcontractor invoices + GST numbers
   – bank & e-transfer statements
   – job logs / seasonal service lists
   – parts receipts (valves, pilots, caps, dampers)
   – vehicle mileage logs
   – ITC spreadsheets
   – import records
   – safety-equipment receipts

2. CRA tests:
   • GST/HST charged on all service components
   • subcontractor validity
   • ITC proof & eligibility
   • logs → invoices → deposits → GST return match
   • imported parts self-assessed?
   • QC/ON/Atlantic rate logic
   • seasonal peak volume vs reported income

3. CRA issues Proposed Audit Adjustment.

4. Mackisen CPA prepares full legal + documentary defense.

Learning insight: CRA reconstructs business activity using parts receipts, seasonal volume, and e-transfer flows.
