Worthington grades B+ for hazard risk
Earthquake risk and radon make Worthington’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #10 of 185 in Manitoba and #940 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The radon share rests on 66 home tests in the survey area, so a few homes move it. The burned-area record misses fires under about 10 ha and most grass and farm fires.

The flood map inventory lists nothing for Worthington
What Canada’s Flood Map Inventory lists for Worthington: who studied flooding and where to see their maps.
NRCan’s inventory is silent on Worthington, so any flood map would be the municipality’s own.
Towns with a flood study on file
No study touches Worthington; in Manitoba, 18% of towns have one, below Canada’s 58%.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Nothing here counts toward Risk; the studies are pointers to the maps their owners keep for Worthington.
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 Worthington faces
Practical steps for Worthington’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?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Wildfire counts one way. For Worthington, 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. 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 Worthington floods.
- 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 Worthington sits in.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Worthington’s census subdivision (a neighbourhood shows its city’s).

How big is the earthquake risk in Worthington?
NRCan’s model expects shaking to cost buildings in Worthington $0.006 a year for every $1,000 of their value, on average over many years.
Does Worthington flood?
The inventory has 0 studies for Worthington, and an empty list isn’t a clean bill: the municipality holds any flood maps.
Is radon a problem in Worthington?
The area’s survey found 12% of 66 tested homes above Health Canada’s guideline, so a three-month test is worth doing in Worthington.
