Radon is about average around Weedon: 7.3% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Weedon grades B for hazard risk, with wildfire counted against it.
What stands out about Weedon’s hazards
Four national sources, each read for Weedon: earthquakes, radon, past fires and flood studies.
What Weedon faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Weedon: B
For Weedon, Risk will be the average of earthquakes and radon, with wildfire added only if it makes the average worse.
Its place: #62 of 507 in Quebec and #1,435 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. The radon share rests on 55 home tests in the survey area, so a few homes move it. Small fires and grass fires are largely missing from the national burned-area record.
Few fires near Weedon: 0% within 5 km, 0% within 25 km
Fires mapped since 1986 around where Weedon’s residents live, and the fuel next to their homes.
The land within 25 km of Weedon burns at 0.001% a year on average, the low band; the typical Canadian town: 0.000%.
Since 1986 the nearest fire to Weedon’s homes came within 16 km, never inside 5 km.
58% of the land within 5 km of Weedon is forest fuel, close to the 55% within 25 km.

Burn rate a year, towns in Quebec · highest of 513
Weedon burns at 0.001% a year, 136th of 513 towns in Quebec; the leader, Mistissini, reaches 0.31%.
Each bar: the yearly average share of land within 25 km of a town’s homes that burned, 1986–2025 (CWFIS); the seven highest towns of 2,500 people or more.
The low band takes in 92% of Canada’s 2,610 towns, Weedon among them, though its rate is above zero; 7.5% rank higher.
Bands of the yearly burn rate: low under 0.05%, moderate under 0.25%, high under 1%, very high 1% or more; towns of 2,500 people or more.

Weedon is on the flood map inventory: 2 studies, latest by Gouvernement du Québec
Flood studies whose area touches Weedon, from NRCan’s inventory, each linked to its owner.
Gouvernement du Québec and others have studied flooding in areas that include Weedon: 2 studies, the latest from 2006.
Towns with a flood study on file
Its flood study sets Weedon apart in Quebec, where 45% of towns have one (Canada: 58%).
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
No single decade dominates: 2 studies for Weedon between the 1990s and the 2000s.
Study dates as the NRCan inventory lists them, one count per study touching Weedon.
Flood is shown here, never graded: a study says where a map exists, not how many of Weedon’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.”

Ordinary seismic risk in Weedon: $0.041 per $1,000 of buildings a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
Weedon’s $0.041 is close to the typical town’s $0.030 (1.4 times as much).
Shaking damage a year per $1,000 of building value
Below the middle in Quebec: Weedon’s $0.041 against a median of $0.14; La Pocatière has $0.48.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Middle of the pack: 43% of Canada’s 2,611 towns have more earthquake risk than Weedon.
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).
Roads, pipes and bridges aren’t in Weedon’s figure, nor landslides or tsunami: it is buildings and shaking.

7.3% of homes tested around Weedon are over the radon guideline

37% of Canada’s 2,611 towns share Weedon’s band of 5 to 10%; 26% sit higher.
Each bar: the share of Canada’s towns of 2,500 people or more whose survey area had that share of tests over 200 Bq/m³.
Basements, soil and how a house is sealed decide its radon, so in Weedon only a test can say.

Get ready for what Weedon faces
Practical steps for Weedon’s hazards, most pressing first.
- 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
- 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 Weedon.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Weedon is its health region’s, the survey’s design unit.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Weedon’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; Weedon’s figure is its subdivision’s.
Questions about flooding and hazards in Weedon
Does Weedon flood?
There is flood mapping for Weedon on the national inventory, each study linked to its owner’s map, none of them graded.
How big is the earthquake risk in Weedon?
Expected earthquake damage in Weedon comes to $0.041 a year for each $1,000 that buildings are worth.
Is radon a problem in Weedon?
The area’s survey found 7.3% of 55 tested homes above Health Canada’s guideline, so a three-month test is worth doing in Weedon.
How is Weedon’s Hazard risk Grade worked out?
Hazard risk gives Weedon B, weighing earthquakes and radon and counting wildfire only against it.
Is Weedon at risk of wildfire?
Some, but Weedon’s low band (0% of nearby land burned since 1986, latest 2009) is short of the level that counts.
