Retrieve the pre-2025 simplified Public Health Unit boundaries

Returns the built-in pre-2025 Ontario Public Health Unit (PHU) boundary layer shipped in inst/extdata/phu_simple_pre2025.rds. This 250 m simplified snapshot preserves the 34-boundary PHU vintage that pre-dates the 2025 boundary changes.

Usage

retrieve_phu_pre2025()

Value

An sf object of 34 simplified pre-2025 PHU boundary MULTIPOLYGONs in WGS 84.

Details

LIO no longer serves this vintage, so the snapshot cannot be refreshed. Use retrieve_phu_simple() for the current bundled PHU boundaries, or retrieve_phu() for the current live LIO layer.

Examples

phu_pre2025 <- retrieve_phu_pre2025()
nrow(phu_pre2025)
#> [1] 34
