Centreville Chicopee grades A− for hazard risk
Two inputs always count for Centreville Chicopee, earthquakes and radon; the third, wildfire, counts only against a town.
Its place: #237 of 866 in Ontario and #594 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Small fires and grass fires are largely missing from the national burned-area record.

Towns with a flood study on file
Mapping in Ontario reaches 69% of towns, Centreville Chicopee included, beside 58% across Canada.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood is shown here, never graded: a study says where a map exists, not how many of Centreville Chicopee’s homes stand in a flood zone.
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.”

Earthquakes cost buildings in Centreville Chicopee $0.022 per $1,000 a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
0.7 times the typical $0.030: Centreville Chicopee’s $0.022 is ordinary.
Nobody publishes earthquake risk for Centreville Chicopee alone, so this card uses the figure for the city of Kitchener.
Shaking damage a year per $1,000 of building value
Below the middle in Ontario: Centreville Chicopee’s $0.022 against a median of $0.043; Alexandria has $0.21.

Centreville Chicopee sits mid-range among Canada’s 2,611 towns: 61% expect more shaking damage.
Each column: the share of Canada’s towns of 2,500 people or more in that range of yearly loss per $1,000 (NRCan, 2022).
The loss is to Centreville Chicopee’s buildings alone, from ground shaking; infrastructure and secondary hazards are left out.

Get ready for what Centreville Chicopee faces
What to do about the hazards Centreville Chicopee faces, and what to ask before you buy.
- Test for three months in winter.
- Over 200 Bq/m³: fix it.
- Kits are cheap; pros test too.
- Never drive through floodwater.
- Move papers and medicines upstairs.
- Ask whether your street is mapped.
- Clear needles and wood nearby.
- Keep a grab-and-go bag ready.
- In smoke, stay in; filter air.
- Has it had a radon test?
- Check the address on the flood map.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Centreville Chicopee is its health region’s, the survey’s design unit.
- Flood studies aren’t flood zones. NRCan’s inventory says where flood mapping exists, not where water goes; the map’s owner is the authority for Centreville Chicopee.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Centreville Chicopee’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Centreville Chicopee’s figure is its subdivision’s.
