The national fire record shows next to nothing around Trinity Bay North, 0% of the land within 25 km since 1986 (0.000% a year). Earthquakes matter little: NRCan’s model puts building losses at $0.010 a year per $1,000 of value, against $0.030 for the typical town. In Health Canada’s survey, just 4% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Trinity Bay North grades A for hazard risk; wildfire is low here, so it earns no credit.

Trinity Bay North grades A for hazard risk
Earthquake risk and radon make Trinity Bay North’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
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.

No flood study is listed for Trinity Bay North
What Canada’s Flood Map Inventory lists for Trinity Bay North: who studied flooding and where to see their maps.
The inventory has nothing for Trinity Bay North, but a local or conservation-authority map may still exist.
Towns with a flood study on file
Mapping in Newfoundland and Labrador reaches 59% of towns, beside 58% across Canada, but not Trinity Bay North.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
The grade leaves flood out, since a study area says nothing about how many of Trinity Bay North’s homes are at risk.
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.”

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