The 2026 Ontario wildfire season is producing sustained smoke events across the entire province — from active Ministry of Natural Resources (MNR) fire zones in Northern Ontario to the heavy transported haze blanketing Ottawa, the National Capital Region, the GTA, and Southern Ontario. Wildfire smoke is not woodsmoke: it is a chemically aggressive mix of acidic sulfates, chlorides, hydrocarbons, formaldehyde, benzene, and heavy-metal-laden ultrafine particulates from burned homes, vehicles, plastics, and insulation. Those particulates begin corroding metals, etching glass, and permanently staining porous finishes within 24–72 hours of landing.
Ottawa is our primary service region — home to 95%+ of our active client base — and crews are staged 24/7/365 across the National Capital Region for sub-90-minute response to Centretown, the Glebe, Westboro, Alta Vista, Sandy Hill, and sub-2-hour response to Kanata, Nepean, Barrhaven, Orleans, Gloucester, Stittsville, and Manotick. We also dispatch across Kingston, Belleville, Brockville, the GTA, and all of Eastern Ontario for wildfire smoke intrusion, soot deposition, and structural fire losses.

Our industry-standard protocol
- 1
Emergency dispatch & site stabilization
24/7/365 crew dispatch to Ottawa, the National Capital Region, Kingston, the GTA, and Eastern Ontario. On arrival: HVAC lockdown to prevent particulate distribution, envelope sealing, and immediate PPE-first inspection with N95/P100 respirators, nitrile gloves, and protective suits.
- 2
IICRC FSRT damage assessment & documentation
Room-by-room photographic baseline, soot deposition mapping, PAH and VOC contamination sampling where scoped, and full Xactimate scope delivered to your insurer within 24 hours. Nothing is discarded before the adjuster signs off.
- 3
HEPA extraction & dry soot removal
Every surface is HEPA-vacuumed and dry-chemical-sponged before any wet cleaning. Wet-cleaning acidic soot first drives corrosive staining permanently into finishes. Contents are inventoried, packed out, and cleaned off-site with ultrasonic and ozone protocols.
- 4
Structural cleaning & residue neutralization
Alkaline cleaners neutralize acidic soot chemistry on framing, drywall, cabinetry, and hard surfaces. Charred framing is shellac-primed with Zinsser B-I-N to permanently lock residual odor at the substrate.
- 5
HVAC decontamination & attic assessment
Full HVAC decontamination — blower housing, coil cleaning, ductwork HEPA-vacuum and antimicrobial, filter media replacement. Attic insulation is assessed for PAH loading and removed under negative-air containment where warranted. Details in our dedicated HVAC and attic guides linked below.
- 6
Thermal fogging, hydroxyl & ozone deodorization
Thermal fogging deploys solvent-based deodorizers at the same droplet size as the original smoke, penetrating porous materials on the same pathways. Hydroxyl generators run in occupied spaces; ozone is deployed in unoccupied spaces for severe losses.
- 7
Reconstruction & post-remediation verification
Drywall, insulation, paint, cabinetry, and flooring reconstruction under one accountable Ottawa project lead. Post-remediation air sampling (TVOC, formaldehyde, PAH where scoped) verifies the space before sign-off, with a PRV letter for your insurer, lender, or buyer file.

Why wildfire smoke is chemically different from a campfire
Modern wildfires do not burn only trees. They burn homes, vehicles, treated lumber, insulation, refrigerants, and electronics. The resulting smoke is loaded with acidic sulfates and chlorides that corrode copper wiring, HVAC coils, faucet finishes, and stainless appliances within days, plus polycyclic aromatic hydrocarbons (PAHs) that absorb into insulation, drywall paper, upholstery, and mattress fibres and outgas for months or years.
This is why professional wildfire smoke remediation is a distinct IICRC discipline (FSRT — Fire and Smoke Restoration Technician), not a deep-clean. Ordinary household cleaning cannot neutralize acidic soot chemistry, and standard vacuums re-aerosolize PM2.5 straight back into the air.
Ottawa & National Capital Region — primary service coverage
Ottawa is the operational centre of our wildfire response. Standard dispatch windows: Ottawa core (Centretown, Glebe, Westboro, Alta Vista, Sandy Hill) under 90 minutes; Kanata, Nepean, Barrhaven, Orleans, Gloucester, Stittsville, Manotick under 2 hours; Carleton Place, Almonte, Smiths Falls, Perth 2–3 hours. Kingston, Belleville, Brockville, and the GTA are covered on the same 24/7/365 dispatch line.
We regularly support Northern Ontario evacuees whose homes are impacted, coordinating remotely with adjusters, MNR recovery teams, and municipal emergency-management offices on scope, timing, and re-entry.
The three hidden-damage failure modes we solve
Wildfire smoke odor that returns after cleaning almost always traces to one of three cavities we specialize in. Each has its own dedicated deep-dive guide:
- Hidden wildfire smoke damage in attic insulation — how PAH-loaded cellulose and fibreglass batts re-release odor into the home for months.
- HVAC ductwork decontamination after wildfire smoke — full blower, coil, and duct protocol so the furnace stops recirculating soot every cycle.
- Permanently removing wildfire smoke odor from your home — the sequenced HEPA + thermal-fog + hydroxyl + shellac protocol that eliminates char smell instead of masking it.
All three link back into the master wildfire recovery guide for the full four-phase family safety and property mitigation workflow.
Insurance, documentation, and Xactimate scope
Every Ontario wildfire smoke scope we deliver is priced in Xactimate — the same software your adjuster uses — with photographic baselines, daily technician logs, contents inventories, and a Post-Remediation Verification (PRV) letter on completion. We bill Intact, Aviva, Co-operators, Wawanesa, Desjardins, TD Insurance, Economical, RSA, and every other major Canadian carrier directly, so most homeowners never pay beyond their deductible.

Frequently asked questions
Do you dispatch crews for wildfire smoke intrusion even if there's no visible fire damage?
Yes. Most Ottawa and GTA wildfire calls involve smoke intrusion without any direct fire contact — invisible PM2.5, acidic soot deposition, and PAH loading in insulation and HVAC. We inspect, sample where warranted, and scope only what is actually contaminated. Sub-90-minute response to the Ottawa core.
How fast can you respond in Ottawa during a heavy wildfire smoke event?
Ottawa is our primary service region with 95%+ of active clients based in the National Capital Region. Standard dispatch is under 90 minutes to the Ottawa core and under 2 hours to Kanata, Nepean, Barrhaven, Orleans, Gloucester, Stittsville, and Manotick — 24/7/365 including statutory holidays.
Will my Ontario homeowner insurance cover wildfire smoke remediation?
Most standard Ontario homeowner policies cover sudden and accidental smoke damage from a wildfire event — cleaning, deodorization, contents restoration, and HVAC decontamination. Notify your insurer within 24–48 hours, document everything before cleaning, and request an IICRC FSRT-certified contractor who delivers scope in Xactimate. We handle the entire claim workflow directly with your carrier.
Do I need attic insulation replaced after a wildfire smoke event?
Sometimes. Blown-in cellulose and fibreglass batts absorb PAHs and phenolic compounds and re-release them for months. We assess loading and only recommend removal where sampling or physical evidence justifies it — never as a default upsell. Full detail in our attic insulation guide.
How is wildfire smoke different from a house-fire cleanup?
Wildfire smoke is distributed (thin films across large surface areas) rather than concentrated near a burn origin. The chemistry is broader — it includes combustion products from burned homes and vehicles miles away, not just wood. Our protocol adjusts scope accordingly: less demolition, more HEPA extraction, deeper HVAC and insulation focus.
Can you handle GTA and Kingston wildfire smoke calls from the same dispatch?
Yes. Kingston, Belleville, Brockville, Toronto, Mississauga, Brampton, Vaughan, Markham, Oakville, Burlington, and the entire GTA are dispatched on the same 24/7/365 emergency line. Response windows vary by distance from the nearest staged crew.
