No wildfire is mapped within 25 km of Disraeli’s homes since 1986 (0% of the land, 0.000% a year). For earthquakes Disraeli is middling, $0.039 a year per $1,000 against $0.030 for the typical town. Hazard risk gives Disraeli a grade of C, from earthquakes and radon alone.
What stands out about Disraeli’s hazards
Four national sources, each read for Disraeli: earthquakes, radon, past fires and flood studies.
What Disraeli faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Disraeli: C
Two inputs always count for Disraeli, earthquakes and radon; the third, wildfire, counts only against a town.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. Small fires and grass fires are largely missing from the national burned-area record.
Few fires near Disraeli: 0% within 5 km, 0% within 25 km
Past fire around Disraeli’s homes, from the national burned-area record, with the fuel within 5 km.
Around Disraeli fire takes 0.000% of the land in a typical year, the typical Canadian town 0.000%, which is low.
More forest grows near Disraeli’s homes (70% within 5 km) than across 25 km (59%).
Shares of land within 5 and 25 km of populated blocks: burned at least once in 1986–2025 (CWFIS burned-area composite), forest fuel and grass (fire behaviour fuel types, 2026, 250 m grid).
Burn rate a year, towns in Quebec · highest of 514
Fire has taken almost none of the land around Disraeli, as for 145 of the 514 towns in Quebec; Mistissini tops the list at 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.
Measured against 2,610 towns, Disraeli is in the largest group, low (92%), and at its floor, while 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.

The flood map inventory lists nothing for Disraeli
What Canada’s Flood Map Inventory lists for Disraeli: who studied flooding and where to see their maps.
No flood study on the national inventory covers Disraeli; ask the municipality, which is the authority for its flood maps.
Towns with a flood study on file
Mapping in Quebec reaches 45% of towns, below the 58% across Canada, and not Disraeli.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood mapping is shown for Disraeli to be opened and checked, never turned into a grade.
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 Disraeli $0.039 per $1,000 a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Disraeli’s $0.039 is close to the typical town’s $0.030 (1.3 times as much).
Shaking damage a year per $1,000 of building value
Below the middle in Quebec: Disraeli’s $0.039 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.
Disraeli’s earthquake risk lands near the centre of Canada’s range; 45% of the 2,611 towns are higher.
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 Disraeli’s buildings alone, from ground shaking; infrastructure and secondary hazards are left out.

13% of homes tested around Disraeli are over the radon guideline
Long-term radon tests in homes across the survey area, against Health Canada’s guideline.
Disraeli’s survey area reads 13% over the guideline, well past the typical Canadian town’s 6.6%. Nobody publishes radon tests for Disraeli alone, so this card uses the figure for the Chaudiere-Appalaches health region.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
Radon runs higher around Disraeli than in most towns in Quebec: 13% over the guideline (8.2% is typical), 0.6% over 600.
Health Canada radon survey (2009–2011), by 2007 health region; medians of towns of 2,500 people or more.
Disraeli is in the 10–20% band, with 22% of Canada’s 2,611 towns; only 4.6% are 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.
One home in Disraeli can be high while next door is low; a three-month test settles it.

Get ready for what Disraeli faces
What to do about the hazards Disraeli 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?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Earthquakes are modelled. Shaking damage is modelled from the ground, the buildings and the odds of each quake, and published for whole subdivisions such as Disraeli’s.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Disraeli’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Disraeli without grading them.
- Radon is a survey. Radon figures pool the survey’s home tests by area: postal areas once their boundaries arrive, the 2007 health region around Disraeli until then.
Questions about flooding and hazards in Disraeli
Is radon a problem in Disraeli?
In Health Canada’s survey, 13% of 175 homes tested in Disraeli’s area were above 200 Bq/m³, though only a test tells you about one house.
