A flood study covers Rexdale-Kipling: 1 on the national inventory, the newest from Toronto Regional Conservation Authority
The burned-area map is nearly blank around Rexdale-Kipling, 0% within 25 km since 1986, 0.000% a year. For earthquakes Rexdale-Kipling is middling, $0.043 a year per $1,000 against $0.030 for the typical town. Fewer homes than usual carry radon here, 2.7% over the guideline where the typical town has 6.6%. Hazard risk gives Rexdale-Kipling a grade of A−, from earthquakes and radon alone.

Flood study
Rexdale-Kipling grades A− for hazard risk
Earthquake risk and radon make Rexdale-Kipling’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #285 of 866 in Ontario and #700 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. Only 74 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.
Little of the land around Rexdale-Kipling has burned: 0% within 5 km, 0% within 25 km since 1986
Past fire around Rexdale-Kipling’s homes, from the national burned-area record, with the fuel within 5 km.
Rexdale-Kipling burns at 0.000% a year, low against 0.000% for the typical Canadian town.
Forest fuel is scarce around Rexdale-Kipling: 0.5% of the land within 5 km, 1.5% within 25 km.
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 Rexdale-Kipling, 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%; Rexdale-Kipling, 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.

Towns with a flood study on file
Flood maps are common in Ontario: 69% of towns have one, against 58% nationally, and Rexdale-Kipling is among them.

Flood is shown here, never graded: a study says where a map exists, not how many of Rexdale-Kipling’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.”

Get ready for what Rexdale-Kipling faces
Practical steps for Rexdale-Kipling’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?
- 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 Rexdale-Kipling’s census subdivision (a neighbourhood shows its city’s).
- Wildfire counts one way. For Rexdale-Kipling, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Radon is a survey. The radon share comes from about 14,000 long-term home tests in 2009–2011, pooled for now by the 2007 health region Rexdale-Kipling sits in.
- Flood studies aren’t flood zones. A study’s area can be a whole watershed or province, so being on the inventory says a map exists, not that a home in Rexdale-Kipling floods.
