Toronto Dryer Vent Fire-Risk Map

TL;DR

In Toronto, three vent configurations account for the majority of dryer-related fires: (1) flex-foil transition ducts over 8 ft, (2) any run over 25 ft with more than two 90° elbows, and (3) rooftop terminations without a proper backdraft damper. Cleaning + code-legal rebuild runs $189–$650. Same-week booking across Toronto.

Why Toronto homes are high-risk

Ontario Building Code 6.3.4 caps a dryer duct at 7.5 m equivalent length (each 90° elbow counts as 1.2 m). Most $Toronto townhouses and infill semis exceed that by design — the laundry is buried in a mid-house closet with a 30-ft run to the exterior wall. That's a lint trap by geometry.

Add flexible foil ("slinky") transition duct — technically illegal under CAN/CSA — and you get the exact setup behind ~2,900 dryer fires a year in North America (NFPA).

Warning signs (any one = book a service)

  • Clothes take more than one cycle to dry.
  • Dryer top or laundry room feels hotter than normal at end of cycle.
  • Burnt-lint smell during operation.
  • External vent hood flapper doesn't open, or lint visible on siding around it.
  • Last cleaning was over 12 months ago.

Toronto pricing (2026)

  • Standard clean (up to 15 ft, ground floor): $189
  • Long run / townhouse clean (up to 30 ft): $259–$329

Our code-legal rebuild spec

  • Rigid galvanized 4" smooth-wall duct — no foil, no vinyl.
  • All joints sealed with UL-181 foil tape (not sheet metal screws — screws catch lint).
  • Minimum 45° elbows where possible; each 90° counted against total length.
  • Backdraft damper at termination, birds/rodent screen on hood only if code-approved (¼" mesh maximum).
  • End-user reset card left at the appliance with duct length and cleaning interval.

FAQ — Dryer Vent Risk in Toronto

How often should I clean my dryer vent in Toronto?+

Annually for single-family homes, every 6 months for townhouses with long runs, and every 3 months for shared-stack condo buildings.

Can I DIY this?+

You can vacuum the lint trap housing safely. Full duct cleaning requires a rotary brush kit and access to the roof or exterior termination — not a homeowner job in most Toronto configurations.

Do you handle rooftop terminations?+

Yes — fully insured, safety-tied, WSIB-covered. Rooftop cleans are our specialty on Toronto townhouses and infill homes.

Will my landlord/condo cover this?+

In-suite vents are almost always tenant/owner responsibility. Vertical stacks in condo buildings are common-element and covered by the condo corporation.
