Fire has left almost no mark near Lakeview: 0% of the land within 25 km since 1986, 0.000% a year. For earthquakes Lakeview is middling, $0.040 a year per $1,000 against $0.030 for the typical town. Radon is lower than usual: 0% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Hazard risk gives Lakeview a grade of A, from earthquakes and radon alone.
What stands out about Lakeview’s hazards
For Lakeview, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.

Hazard risk in Lakeview: A
The grade weighs Lakeview’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
Its place: #194 of 866 in Ontario and #529 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Few fires near Lakeview: 0% within 5 km, 0% within 25 km
Past fire around Lakeview’s homes, from the national burned-area record, with the fuel within 5 km.
Forty years of fire maps put Lakeview at 0.000% a year, low next to the typical Canadian town’s 0.000%.
Forest makes up 0.5% of the land within 5 km of Lakeview and 0.5% within 25 km, little for a forest fire to run through.
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
Fire has taken almost none of the land around Lakeview, as for 638 of the 871 towns in Ontario; Sioux Lookout tops the list at 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.
Only 7.5% of Canada’s 2,610 towns are above the low band, which holds 92%; Lakeview, at a rounded zero, is far from them.
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.

What Canada’s Flood Map Inventory lists for Lakeview: who studied flooding and where to see their maps.
6 studies on the inventory touch Lakeview, the newest Toronto Regional Conservation Authority’s from 2021, and their areas can be large, so they say maps exist, not that the town floods.

Towns with a flood study on file
Its flood study puts Lakeview 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.
The busiest decade for flood studies around Lakeview was the 2010s (4 of 6); they run from the 2000s to the 2020s.
Study dates as the NRCan inventory lists them, one count per study touching Lakeview.
Flood mapping is shown for Lakeview 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.”

Get ready for what Lakeview faces
What to do about the hazards Lakeview 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.
- 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
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Lakeview’s census subdivision (a neighbourhood shows its city’s).
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Lakeview is its health region’s, the survey’s design unit.
- Wildfire counts one way. For Lakeview, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- 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 Lakeview.
Questions about flooding and hazards in Lakeview
How is Lakeview’s Hazard risk Grade worked out?
Lakeview grades A for hazard risk, from earthquakes and radon, with wildfire counted only where it lowers the grade.
Is Lakeview at risk of wildfire?
Very little by the national record: Lakeview’s band is low, with 0% of the land within 25 km burned since 1986, so wildfire doesn’t change its grade.
Is radon a problem in Lakeview?
Around Lakeview, 90 survey homes were tested and 0% came in over 200 Bq/m³, a guide to the area, not to any one home.
Does Lakeview flood?
There is flood mapping for Lakeview on the national inventory, each study linked to its owner’s map, none of them graded.
How big is the earthquake risk in Lakeview?
In NRCan’s seismic model, Lakeview’s buildings lose $0.040 per $1,000 of value in an average year.
