Hazard risk in Barbertown is lower than in 86% of Canadian towns

The national fire record shows next to nothing around Barbertown, 0% of the land within 25 km since 1986 (0.000% a year). Shaking is about as much of a worry in Barbertown as in most places, at $0.040 a year per $1,000 of building value ($0.030 typical). In Health Canada’s survey, just 0% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Barbertown grades A for hazard risk; wildfire is low here, so it earns no credit.

In brief

What stands out about Barbertown’s hazards

For Barbertown, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.

By hazard

What Barbertown faces

Each hazard against its own yardstick; meters run from low to high on that yardstick.

Not on this page: flood zones and homes in them, past floods, landslides, industrial sites and storm surge: Canada has no national open source for them by town.
Hazard risk Grade

Hazard risk in Barbertown: A

For Barbertown, Risk will be the average of earthquakes and radon, with wildfire added only if it makes the average worse.

Earthquake risk ($0.040)Better than 44% of Canadian towns
Radon (0%)Better than 97% of Canadian towns
Wildfire (one-sided) (Low)Not counted: it would have raised the grade
Flood study (Yes)Shown, never graded

Its place: #194 of 866 in Ontario and #529 of 2,589 Canadian towns.

How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. The burned-area record misses fires under about 10 ha and most grass and farm fires.

Wildfire

Wildfire is rare near Barbertown: 0% of the land within 25 km burned since 1986, 0% within 5 km

Past fire around Barbertown’s homes, from the national burned-area record, with the fuel within 5 km.

The inventory’s own caution (NRCan): “The Canada Flood Map (CFM) does not include every flood hazard map in Canada and may be incomplete or contain inaccuracies. It should not be relied upon as the official source of flood mapping information. Furthermore, if a map appears to be missing, this does not necessarily mean that the area has never been mapped. For the official version of a map, updated information, or confirmation of applicable regulations, please contact the local authority responsible for flood mapping.”

Practical steps for Barbertown’s hazards, most pressing first.

Radon
  • Test for three months in winter.
  • Over 200 Bq/m³: fix it.
  • Kits are cheap; pros test too.
Take Action on Radon
When the river rises
  • Never drive through floodwater.
  • Move papers and medicines upstairs.
  • Ask whether your street is mapped.
Alert Ready
Wildfire season
  • Clear needles and wood nearby.
  • Keep a grab-and-go bag ready.
  • In smoke, stay in; filter air.

How to read these numbers

What this data can and can’t tell you

  • Flood studies aren’t flood zones. The flood inventory points to maps; it is incomplete and not the official source, so ask the municipality about any street in Barbertown.
  • Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Barbertown’s included.
  • Wildfire counts one way. Burned land within 25 km of where people live, averaged over 1986–2025 and checked for fuel near homes, is the measure; it looks back, not ahead, and only ever counts against Barbertown.
  • Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Barbertown takes its 2007 health region’s share.
