How to read Canada
Lifestyle underground
Canadian public evidence skews toward earth-sheltered or underground homes rather than separable hardened bunker assets.
Reading notes
- Prices often reflect rural residential utility, land, and energy-efficiency or lifestyle value.
- Dedicated bunker-only comps should be separated from bermed or earth-sheltered houses when they appear.

- Transferable REStandard real estate. Clean title, transferable like any house.
- Shelter built into a broader property. You buy the property, the shelter comes with it.
- Lifestyle undergroundUnderground or earth-sheltered home. Buyable like any house; hardening is usually below bunker grade.
