Hazards in Downtown Commercial Core · NRCan, Health Canada, CWFIS

Downtown Commercial Core is on Canada’s flood inventory: 1 listed, led by Government of Alberta

The burned-area map is nearly blank around Downtown Commercial Core, 0% within 25 km since 1986, 0.000% a year. NRCan expects $0.023 of shaking damage a year per $1,000 of buildings in Downtown Commercial Core, near the typical $0.030. About as many homes carry radon around Downtown Commercial Core as elsewhere, 8.1% over the guideline where the typical town has 6.6%. Downtown Commercial Core grades B+ for hazard risk; wildfire is low here, so it earns no credit.

In brief

What stands out about Downtown Commercial Core’s hazards

For Downtown Commercial Core, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.

By hazard

What Downtown Commercial Core 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

Downtown Commercial Core grades B+ for hazard risk

For Downtown Commercial Core, Risk will be the average of earthquakes and radon, with wildfire added only if it makes the average worse.

Earthquake risk ($0.023)Better than 57% of Canadian towns
Radon (8.1%)Better than 57% of Canadian towns
Wildfire (one-sided) (Low)Not counted: it would have raised the grade
Flood study (Yes)Shown, never graded

Its place: #282 of 474 in Alberta and #1,102 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.

Wildfire is rare near Downtown Commercial Core: 0% of the land within 25 km burned since 1986, 0% within 5 km

Flood is shown here, never graded: a study says where a map exists, not how many of Downtown Commercial Core’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.”

How to read these numbers

What this data can and can’t tell you

  • 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 Downtown Commercial Core.
  • Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Downtown Commercial Core’s included.
  • 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 Downtown Commercial Core.
  • Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Downtown Commercial Core is its health region’s, the survey’s design unit.
