Memramcook grades C for hazard risk
Two inputs always count for Memramcook, earthquakes and radon; the third, wildfire, counts only against a town.
Its place: #12 of 60 in New Brunswick and #2,102 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Little of the land around Memramcook has burned: 0% within 5 km, 0.1% within 25 km since 1986
Fires mapped since 1986 around where Memramcook’s residents live, and the fuel next to their homes.
In a typical year 0.002% of the land near Memramcook burns; the typical Canadian town sees 0.000%, and both are low.
The 5 km ring around Memramcook’s homes is clear of burns since 1986, the nearest 6.0 km out.
About as much forest grows next to Memramcook’s homes (61% within 5 km) as across 25 km (65%).

Towns with a flood study on file
Memramcook is one of the 93% of towns in New Brunswick with a flood study on file; across Canada it is 58%.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood is shown here, never graded: a study says where a map exists, not how many of Memramcook’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.”

Ordinary seismic risk in Memramcook: $0.021 per $1,000 of buildings a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
Memramcook’s $0.021 is close to the typical town’s $0.030 (0.7 times as much).
Shaking damage a year per $1,000 of building value
At $0.021, Memramcook is below the typical town in New Brunswick ($0.036); St. Stephen is highest at $0.16.

Test for radon in Memramcook: 20% of area homes were over the guideline
Health Canada’s survey of long-term home tests: the share above the 200 Bq/m³ guideline. · Measured across the Region 1 health region: radon tests
Memramcook’s area, at 20%, is above the 6.6% of the typical Canadian town, so testing is worth more here than most places.
Tested homes over 200 Bq/m³

Get ready for what Memramcook faces
What to do about the hazards Memramcook 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
- 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 Memramcook.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Memramcook without grading them.
- Radon is a survey. Radon figures pool the survey’s home tests by area: postal areas once their boundaries arrive, the 2007 health region around Memramcook until then.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Memramcook’s included.
