Grand Bank grades A− for hazard risk
Seismic risk and radon set Grand Bank’s grade, wildfire can drag it down, and flood mapping stays out of it.
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.
Wildfire is rare near Grand Bank: 0% of the land within 25 km burned since 1986, 0% within 5 km
Past fire around Grand Bank’s homes, from the national burned-area record, with the fuel within 5 km.
At 0.000% of the land a year, Grand Bank’s burn rate is in the low band; the typical Canadian town sees 0.000%.

No flood study is listed for Grand Bank
What Canada’s Flood Map Inventory lists for Grand Bank: who studied flooding and where to see their maps.
No flood study on the national inventory covers Grand Bank; ask the municipality, which is the authority for its flood maps.
Towns with a flood study on file
Flood maps are common in Newfoundland and Labrador, 59% of towns against 58% nationally, but none in the inventory touches Grand Bank.

Flood studies don’t enter the grade; they are listed so you can open the official map for Grand Bank.
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 Grand Bank faces
Practical steps for Grand Bank’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?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
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 Grand Bank.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Grand Bank’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. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Grand Bank takes its 2007 health region’s share.
- 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 Grand Bank’s.
