Fire seldom reaches Lumsden No. 189: since 1986, 0.1% of the land within 25 km has burned (0.002% a year). Shaking is less of a worry than in most places, at $0.008 a year per $1,000 of building value ($0.030 typical). Hazard risk gives Lumsden No. 189 a grade of B−; its wildfire band pulls it down.
What stands out about Lumsden No. 189’s hazards
Four national sources, each read for Lumsden No. 189: earthquakes, radon, past fires and flood studies.

Hazard risk in Lumsden No. 189: B−
For Lumsden No. 189, Risk will be the average of earthquakes and radon, with wildfire added only if it makes the average worse.
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 Lumsden No. 189: 0% within 5 km, 0.1% within 25 km
Past fire around Lumsden No. 189’s homes, from the national burned-area record, with the fuel within 5 km.

Study dates as the NRCan inventory lists them, one count per study touching Lumsden No. 189.
Flood is shown here, never graded: a study says where a map exists, not how many of Lumsden No. 189’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.”

Get ready for what Lumsden No. 189 faces
Practical steps for Lumsden No. 189’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
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Lumsden No. 189 is its health region’s, the survey’s design unit.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Lumsden No. 189’s figure is its subdivision’s.
- 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 Lumsden No. 189.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Lumsden No. 189’s homes since 1986, a history of fire that may lower Risk but never raises it.
Questions about flooding and hazards in Lumsden No. 189
How big is the earthquake risk in Lumsden No. 189?
NRCan’s model expects shaking to cost buildings in Lumsden No. 189 $0.008 a year for every $1,000 of their value, on average over many years.
Does Lumsden No. 189 flood?
There is flood mapping for Lumsden No. 189 on the national inventory, each study linked to its owner’s map, none of them graded.
How is Lumsden No. 189’s Hazard risk Grade worked out?
Hazard risk gives Lumsden No. 189 B−, weighing earthquakes and radon and counting wildfire only against it.
Is Lumsden No. 189 at risk of wildfire?
Not much by Canadian standards: Lumsden No. 189’s band is low, with 0.1% of the land within 25 km burned since 1986 (last in 2024), so wildfire doesn’t change its grade.
Is radon a problem in Lumsden No. 189?
25% of the 94 homes Health Canada tested around Lumsden No. 189 topped the guideline; your own house needs its own test.
