Fire seldom reaches Parc-Jarry: since 1986, 0.1% of the land within 25 km has burned (0.002% a year). Shaking is a bigger worry than in most places, at $0.20 a year per $1,000 of building value ($0.030 typical). Hazard risk gives Parc-Jarry a grade of C, from earthquakes and radon alone.
What stands out about Parc-Jarry’s hazards
Four national sources, each read for Parc-Jarry: earthquakes, radon, past fires and flood studies.
What Parc-Jarry faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.
Wildfire
Earthquakes
Radon
Flood study
Hazard risk in Parc-Jarry: C
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Parc-Jarry with little fire nearby would get no credit for it.
Its place: #161 of 507 in Quebec and #2,110 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The radon share rests on 74 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.
Wildfire is rare near Parc-Jarry: 0.1% of the land within 25 km burned since 1986, 0% within 5 km

The flood map inventory lists nothing for Parc-Jarry
What Canada’s Flood Map Inventory lists for Parc-Jarry: who studied flooding and where to see their maps.
Nationally, Parc-Jarry has no listed flood study; the municipality is the place to ask.
Towns with a flood study on file
Only 45% of towns in Quebec have a flood study, short of Canada’s 58%, and Parc-Jarry is not among 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 Parc-Jarry’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 Parc-Jarry’s costliest hazard: $0.20 a year per $1,000
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
The typical town loses $0.030 a year to shaking; Parc-Jarry loses $0.20, 6.7 times as much.
Nobody publishes earthquake risk for Parc-Jarry alone, so this card uses the figure for the city of Montréal.
Shaking damage a year per $1,000 of building value
Earthquake risk in Quebec peaks in La Pocatière ($0.48); Parc-Jarry, at $0.20, 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.
Only 8.5% of Canada’s 2,611 towns expect more shaking damage than Parc-Jarry.
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 Parc-Jarry’s buildings alone, from ground shaking; infrastructure and secondary hazards are left out.

Get ready for what Parc-Jarry faces
What to do about the hazards Parc-Jarry 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.
- Drop, cover and hold on.
- Strap the water heater down.
- Keep 72 hours of supplies.
- Has it had a radon test?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
- Is earthquake cover included?
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 Parc-Jarry’s.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Parc-Jarry without grading them.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Parc-Jarry’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- 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 Parc-Jarry until then.
