Wildfire is a real hazard for La Broquerie: 9.7% of the land within 25 km has burned since 1986, 0.28% a year, in the high band. Earthquakes matter little: NRCan’s model puts building losses at $0.005 a year per $1,000 of value, against $0.030 for the typical town. Radon is about average around La Broquerie: 9.7% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Hazard risk gives La Broquerie a grade of D−; its wildfire band pulls it down.

La Broquerie grades D− for hazard risk
For La Broquerie, Risk will be the average of earthquakes and radon, with wildfire added only if it makes the average worse.
Its place: #180 of 185 in Manitoba and #2,541 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Fire country: 9.7% of the land within 25 km of La Broquerie has burned since 1986, 0.1% within 5 km
Fires mapped since 1986 around where La Broquerie’s residents live, and the fuel next to their homes.
At 0.28% of the land a year, La Broquerie’s burn rate is high, many times the typical Canadian town’s 0.000%.
Forest fuel rises from 2.3% within 5 km of La Broquerie to 19% within 25 km: the fuel lies away from homes.
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 Manitoba · highest of 189
La Broquerie ranks 6th of the 189 towns in Manitoba for burn rate, at 0.28% a year; Flin Flon (Part) leads with 1.68%.
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.
Just 1.9% of Canada’s 2,610 towns burn fast enough for the high band where La Broquerie sits; 0.2% burn faster.
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.

Nothing here counts toward Risk; the studies are pointers to the maps their owners keep for La Broquerie.
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.”

Little shaking expected in La Broquerie: $0.005 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.
At $0.005 per $1,000, La Broquerie carries 0.2 times the typical Canadian town’s earthquake risk ($0.030): low.
Shaking damage a year per $1,000 of building value
Shaking damage around La Broquerie runs at $0.005 a year, near the $0.006 of the typical town in Manitoba; Virden has $0.007.

Get ready for what La Broquerie faces
Practical steps for La Broquerie’s hazards, most pressing first.
- Clear needles and wood nearby.
- Keep a grab-and-go bag ready.
- In smoke, stay in; filter air.
- 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.
- Has it had a radon test?
- Check the address on the flood map.
- How close is the forest edge?
- Are flood and wildfire insured?
What this data can and can’t tell you
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for La Broquerie’s census subdivision (a neighbourhood shows its city’s).
- Wildfire counts one way. For La Broquerie, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- 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 La Broquerie.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, La Broquerie takes its 2007 health region’s share.
Questions about flooding and hazards in La Broquerie
How big is the earthquake risk in La Broquerie?
Expected earthquake damage in La Broquerie comes to $0.005 a year for each $1,000 that buildings are worth.
Is La Broquerie at risk of wildfire?
