Since 1986 almost nothing has burned near City View: 0% of the land within 25 km, or 0.000% a year. Seismic risk runs high: $0.15 of expected damage per $1,000 of buildings a year, the typical town $0.030. City View grades C+ for hazard risk; wildfire is low here, so it earns no credit.
What stands out about City View’s hazards
For City View, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.
What City View faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in City View: C+
The grade weighs City View’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Only 64 homes were tested in the survey area, so the radon share is rough. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Wildfire is rare near City View: 0% of the land within 25 km burned since 1986, 0% within 5 km
Fires mapped since 1986 around where City View’s residents live, and the fuel next to their homes.
City View burns at 0.000% a year, low against 0.000% for the typical Canadian town.
The closest burn since 1986 lies 19 km from City View’s homes, none within 5 km.
Homes in City View sit on open or built-up ground (1.5% forest fuel within 5 km); the wider 25 km holds 8.2%.
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 Ontario · highest of 871
To three decimals the burn rate around City View is zero, as for 638 of the 871 towns in Ontario, while Sioux Lookout reaches 0.16%.
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.
Like most of Canada’s 2,610 towns (92%), City View is in the low band, with a burn rate of zero to three decimals; 7.5% rank higher.
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.

No flood study is listed for City View
Flood studies whose area touches City View, from NRCan’s inventory, each linked to its owner.
An empty entry for City View on the inventory isn’t proof of safety; ask locally for flood maps.
Towns with a flood study on file
Missing from a well-mapped province: City View has no study, where 69% of towns in Ontario have one against 58% nationally.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood mapping is shown for City View to be opened and checked, never turned into a grade.
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.”
Earthquakes cost buildings in City View $0.15 per $1,000 a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
At $0.15 per $1,000, City View carries roughly 5 times the typical Canadian town’s earthquake risk ($0.030).
Behind earthquake risk sits data gathered across the city of Ottawa, with City View one part of it.
Shaking damage a year per $1,000 of building value
Above the middle in Ontario: City View’s $0.15 against a median of $0.043, with Alexandria highest at $0.21.

Get ready for what City View faces
What to do about the hazards City View faces, and what to ask before you buy.
- 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.
- Strap the water heater down.
- Keep 72 hours of supplies.
- Has it had a radon test?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
- Is earthquake cover included?
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 City View.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, City View’s included.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, City View takes its 2007 health region’s share.
- Wildfire counts one way. Burned land within 25 km of where people live, averaged over 1986–2025 and checked for fuel near homes, is the measure; it looks back, not ahead, and only ever counts against City View.
