Burn scars are few around Fabreville, with 0% of the land within 25 km touched by fire since 1986 (0.001% a year). Seismic risk runs high: $0.21 of expected damage per $1,000 of buildings a year, the typical town $0.030. In Health Canada’s survey, 12% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Fabreville grades D for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Fabreville’s hazards
Four national sources, each read for Fabreville: earthquakes, radon, past fires and flood studies.

Fabreville grades D for hazard risk
Earthquake risk and radon make Fabreville’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #485 of 507 in Quebec and #2,507 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.
Few fires near Fabreville: 0% within 5 km, 0% within 25 km
Fires mapped since 1986 around where Fabreville’s residents live, and the fuel next to their homes.
A burn rate of 0.001% a year keeps Fabreville in the low band (the typical Canadian town: 0.000%).
Forest makes up 0.1% of the land within 5 km of Fabreville and 3.2% within 25 km, little for a forest fire to run through.
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 513
Fabreville sits mid-table in Quebec: 136th of 513 towns, at 0.001% a year, well behind Mistissini (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.
7.5% of Canada’s 2,610 towns burn fast enough to rank moderate or above; Fabreville stays low, with 92%.
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.

A flood study covers Fabreville, from Gouvernement du Québec: 1 on the inventory
Flood studies whose area touches Fabreville, from NRCan’s inventory, each linked to its owner.
One study on the inventory touches Fabreville, Gouvernement du Québec’s from 2006, and its area can be large, so it says a map exists, not that the town floods.
| Study | By | Year | Status |
|---|---|---|---|
| Moulins-Thérèse-De-Blainville-Deux-Montagnes-Laval | Gouvernement du Québec | 2006 | final |
Towns with a flood study on file
Only 45% of towns in Quebec have a flood study, short of Canada’s 58%; Fabreville is one of them.
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 Fabreville’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.”

Shaking is Fabreville’s costliest hazard: $0.21 a year per $1,000
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
Fabreville’s $0.21 is about 6.9 times the typical town’s $0.030: it sits in one of Canada’s more active seismic zones.
Fabreville doesn’t get its own earthquake risk figures; the ones here come from the city of Laval.
Shaking damage a year per $1,000 of building value
Earthquake risk in Quebec peaks in La Pocatière ($0.48); Fabreville, at $0.21, sits above the median of $0.14.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Fabreville is in the top tenth of Canada’s 2,611 towns for earthquake risk; 7.9% rank 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 Fabreville’s buildings alone, from ground shaking; infrastructure and secondary hazards are left out.

Get ready for what Fabreville faces
Practical steps for Fabreville’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.
- Drop, cover and hold on.
- Strap the water heater down.
- Keep 72 hours of supplies.
- Has it had a radon test?
- Check the address on the flood map.
- Are flood and wildfire insured?
- Is earthquake cover included?
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 Fabreville.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Fabreville’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Fabreville takes its 2007 health region’s share.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Fabreville’s figure is its subdivision’s.
Questions about flooding and hazards in Fabreville
How is Fabreville’s Hazard risk Grade worked out?
Fabreville’s Hazard risk grade is D, built on earthquakes and radon with a one-sided wildfire input.
How big is the earthquake risk in Fabreville?
About $0.21 a year per $1,000 of building value, NRCan’s long-run expectation for Fabreville.
Is Fabreville at risk of wildfire?
Not much by Canadian standards: Fabreville’s band is low, with 0% of the land within 25 km burned since 1986 (last in 2025), so wildfire doesn’t change its grade.
Is radon a problem in Fabreville?
12% of the 107 homes Health Canada tested around Fabreville topped the guideline; your own house needs its own test.
Does Fabreville flood?
The inventory lists a study touching Fabreville; whether a given street floods is on that map, not in the grade.
