Flood mapping exists for Qualicum - Redwood: 1 on record, latest by Rideau Valley Conservation Authority
Wildfire isn’t Qualicum - Redwood’s worry: 0% of the land within 25 km burned since 1986 (0.001% a year). Seismic risk runs high: $0.15 of expected damage per $1,000 of buildings a year, the typical town $0.030. Radon is about average around Qualicum - Redwood: 6.2% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Qualicum - Redwood grades C+ for hazard risk; wildfire is low here, so it earns no credit.

Qualicum - Redwood grades C+ for hazard risk
Seismic risk and radon set Qualicum - Redwood’s grade, wildfire can drag it down, and flood mapping stays out of it.
Its place: #703 of 866 in Ontario and #1,894 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. The radon share rests on 64 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.
Few fires near Qualicum - Redwood: 0% within 5 km, 0% within 25 km
Fires mapped since 1986 around where Qualicum - Redwood’s residents live, and the fuel next to their homes.
Next to the typical Canadian town (0.000% a year), Qualicum - Redwood’s 0.001% is in the low band.
Qualicum - Redwood’s homes have had no fire within 5 km since 1986; the closest was 17 km away.
Close to Qualicum - Redwood there is little to burn (4.3% forest fuel within 5 km), but 9.3% of the land within 25 km is forest.
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).

Towns with a flood study on file
Its flood study puts Qualicum - Redwood with 69% of towns in Ontario; Canada’s share is 58%.
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 Qualicum - Redwood’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 Qualicum - Redwood’s costliest hazard: $0.15 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.
Roughly 5 times the typical $0.030: Qualicum - Redwood’s $0.15 marks real seismic exposure.
Shaking damage a year per $1,000 of building value
Qualicum - Redwood’s $0.15 tops the median in Ontario, $0.043, though Alexandria reaches $0.21.

Get ready for what Qualicum - Redwood faces
Practical steps for Qualicum - Redwood’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.

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 Qualicum - Redwood is its health region’s, the survey’s design unit.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Qualicum - Redwood’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Qualicum - Redwood’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 Qualicum - Redwood.
