Mimico-Queensway is on Canada’s flood inventory: 1 listed, led by Toronto Regional Conservation Authority

The burned-area map is nearly blank around Mimico-Queensway, 0% within 25 km since 1986, 0.000% a year. Seismic risk in Mimico-Queensway sits near the middle: $0.043 of expected damage per $1,000 of buildings a year, the typical town $0.030. In Health Canada’s survey, just 2.7% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Mimico-Queensway grades A− for hazard risk; wildfire is low here, so it earns no credit.

In brief

What stands out about Mimico-Queensway’s hazards

Four national sources, each read for Mimico-Queensway: earthquakes, radon, past fires and flood studies.

By hazard

What Mimico-Queensway faces

Each hazard against its own yardstick; meters run from low to high on that yardstick.

Not on this page: flood zones and homes in them, past floods, landslides, industrial sites and storm surge: Canada has no national open source for them by town.
Hazard risk Grade

Hazard risk in Mimico-Queensway: A−

Earthquake risk and radon make Mimico-Queensway’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.

Earthquake risk ($0.043)Better than 41% of Canadian towns
Radon (2.7%)Better than 84% of Canadian towns
Wildfire (one-sided) (Low)Not counted: it would have raised the grade
Flood study (Yes)Shown, never graded

Its place: #285 of 866 in Ontario and #700 of 2,589 Canadian towns.

How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Only 74 homes were tested in the survey area, so the radon share is rough. Small fires and grass fires are largely missing from the national burned-area record.

Wildfire

Wildfire is rare near Mimico-Queensway: 0% of the land within 25 km burned since 1986, 0% within 5 km

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.

How to read these numbers

What this data can and can’t tell you

  • 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 Mimico-Queensway’s.
  • Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Mimico-Queensway is its health region’s, the survey’s design unit.
  • Wildfire counts one way. The wildfire figure is the share of land within 25 km of Mimico-Queensway’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
  • 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 Mimico-Queensway.
