Hazard risk in Eastdale: B+
Seismic risk and radon set Eastdale’s grade, wildfire can drag it down, and flood mapping stays out of it.
Its place: #494 of 866 in Ontario and #1,255 of 2,589 Canadian towns.
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.
Little of the land around Eastdale has burned: 0% within 5 km, 0% within 25 km since 1986
Past fire around Eastdale’s homes, from the national burned-area record, with the fuel within 5 km.
The yearly burn rate around Eastdale is 0.000%, low beside 0.000% for the typical Canadian town.
Only 0.6% of the land within 25 km of Eastdale is forest fuel, and 0% close in.

No flood study is listed for Eastdale
What Canada’s Flood Map Inventory lists for Eastdale: who studied flooding and where to see their maps.
No flood study on the national inventory covers Eastdale; ask the municipality, which is the authority for its flood maps.
Towns with a flood study on file
Flood maps are common in Ontario, 69% of towns against 58% nationally, but none in the inventory touches Eastdale.
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 Eastdale’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.”
Expected shaking damage in Eastdale: $0.044 a year per $1,000
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Eastdale’s $0.044 is close to the typical town’s $0.030 (1.5 times as much).
Shaking damage a year per $1,000 of building value
Eastdale’s $0.044 is close to the median in Ontario, $0.043; Alexandria is highest at $0.21.

Get ready for what Eastdale faces
Practical steps for Eastdale’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
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Eastdale’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- 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 Eastdale’s.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Eastdale takes its 2007 health region’s share.
- 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 Eastdale.
Questions about flooding and hazards in Eastdale
How big is the earthquake risk in Eastdale?
NRCan’s model expects shaking to cost buildings in Eastdale $0.044 a year for every $1,000 of their value, on average over many years.
Is Eastdale at risk of wildfire?
Hardly at all on record: 0% of the land within 25 km of Eastdale since 1986, a low band, though small grass fires aren’t mapped.
Does Eastdale flood?
The inventory has 0 studies for Eastdale, and an empty list isn’t a clean bill: the municipality holds any flood maps.
How is Eastdale’s Hazard risk Grade worked out?
Hazard risk gives Eastdale B+, weighing earthquakes and radon and counting wildfire only against it.
Is radon a problem in Eastdale?
The area’s survey found 5% of 100 tested homes above Health Canada’s guideline, so a three-month test is worth doing in Eastdale.
